- Verdict: the best ProForm treadmill maintenance kit
The best ProForm treadmill maintenance kit for most owners is the TreadLife Fitness Treadmill Maintenance Kit, with five lubricant applications, a folding applicator and directions.
That mix suits owners who keep the treadmill in regular use. Five sessions cover a longer stretch of routine care, while the folding wand is easier to store in a home gym or garage.
Choose Hydra if you want a 16 in applicator. Its single 2 fluid oz bottle keeps things simple for a focused belt-lubrication task.
Choose Slick-Stick for individual packets, which let you set aside one dose at a time without measuring from a bottle.
Choose Icon Health & Fitness when you need a confirmed motor brush replacement. That part is for a specific repair, not for routine belt care.
ProForm maintenance usually involves more than one task. Belt lubrication helps reduce friction between the belt and deck, while cleaning removes dirt and dust that collect under the belt.
Some machines may need a model-specific replacement part. A motor brush, for example, is separate from lubricant and must match the exact model.
It helps to sort your needs before you buy. If the belt feels dry or noisy, lubrication is the likely starting point, and if the motor shows a fault, check the part number first.
Applicator length is another practical detail. A longer wand reaches farther under the belt, while a shorter wand may be easier to control on tighter machines.
Use our guide on How To Maintain Your Treadmill? for a broader routine covering cleaning, inspection and lubrication as one simple schedule.
If you want to compare more general belt-care options, see our Best Treadmill Maintenance Kit roundup for light, moderate or heavy use.
Always check your ProForm manual before you apply a product. It sets the amount, timing and basic steps for your exact machine.
A small amount of care at regular intervals usually works better than waiting for a problem. It also makes changes in belt movement easier to notice early.
Keep the machine unplugged during basic maintenance. Set up a clean area with good light so you can see the belt edges and track alignment.
Store lubricant away from heat and out of reach of children and pets. Even a non-toxic formula needs normal household care and tidy storage.
Match the product to the task, and you will get more from the purchase. Belt care, cleaning and motor parts each solve a different problem.

The best ProForm treadmill maintenance kit options
The best choice depends on whether you need recurring belt lubrication, a long applicator, measured packets or a specific motor part. The five options below are listed from the highest score to the lowest.
Our score weighs specs, features and buyer feedback against what you're shopping for. We compared the stated lubricant supply, applicator reach, included parts and ProForm-related compatibility.
Hydra TreadLube Treadmill Walking Belt Lubricating Kit: Best for long applicator reach
- 2 fluid oz of silicone lubricant
- 16 in applicator
- Non-toxic formula
- Works with most treadmill models
The 16 in applicator gives you useful reach under a treadmill belt, while the 2 fluid oz bottle keeps the kit focused on belt lubrication.
Pros
- 16 in applicator
- High-viscosity silicone
- Made in USA
Cons
- One bottle
- Not a motor replacement part
Hydra TreadLube is the best fit when you want a dedicated belt lubricant with a long applicator and a compact bottle. The kit contains 2 fluid oz of 100% silicone lubricant and a 16 in applicator, giving you reach under the belt without needing a wide supply of separate packets.
Hydra Fitness Exchange describes the formula as non-toxic and heat-resistant. The product is made in the United States, and its high-viscosity silicone is intended to reduce friction between the treadmill belt and deck.
The 16 in applicator is useful when the belt sits far enough from the edge that a short tool would be awkward. Apply only the amount recommended for your machine, then follow the treadmill's instructions for running the belt after lubrication.
This kit works with most treadmill models, but that broad compatibility does not replace checking your ProForm manual. It is a belt-care choice, not a repair kit for a motor, roller or electronics.
Choose Hydra when applicator reach and a single bottle matter most. It is less suited to owners who want several pre-measured maintenance sessions in one package.
TreadLife Fitness Treadmill Maintenance Kit: Best for scheduled belt care
- Five lubricant applications
- Extra-wide 22 in TruLube applicator wand
- Folding applicator
- Directions included
Five lubricant applications make this the strongest fit for owners planning regular belt care. The folding 22 in wand reaches farther under the belt than shorter applicators.
Pros
- Five applications
- 22 in applicator
- Directions included
Cons
- More supplies than occasional users need
- Belt lubrication only
TreadLife Fitness Treadmill Maintenance Kit is the best ProForm treadmill maintenance kit for owners who want to plan regular belt care. It includes five lubricant applications, a folding applicator and directions, so one purchase supports multiple maintenance sessions.
The extra-wide 22 in TruLube applicator wand is the key advantage. It reaches farther under the belt and spreads the 100% silicone lubricant across a wider area, which can make routine application easier on a large home treadmill.
TreadLife recommends about three months or 130 miles under normal use, with more frequent checks for heavier use. Its directions say to apply about ½ oz to the wand, slide it under the belt, and run the treadmill for 3 to 5 minutes to spread the lubricant.
The five-use supply favors owners who keep a regular care schedule. It may be more than you need if your ProForm manual calls for infrequent lubrication or if you are maintaining a treadmill only once before selling it.
Choose this kit for recurring belt maintenance and maximum applicator reach. It does not replace a model-specific motor part.
TreadLife Fitness Slick-Stick Treadmill Maintenance Kit: Best for mess-free packet use
- Five lubricant packets
- 15 in applicator wand
- Step-by-step instructions
- Non-toxic, odorless silicone formula
Individual packets make the amount easier to separate by maintenance session. The 15 in wand is long enough for routine belt application on many home treadmills.
Pros
- Five individual packets
- 15 in wand
- Odorless formula
Cons
- Shorter wand than the 22 in kit
- Packet format may be less convenient to store
Slick-Stick is the best option for owners who prefer individual lubricant packets instead of one bottle. The kit includes five packets, a 15 in applicator wand and step-by-step instructions.
Each packet helps separate the lubricant supply by maintenance session. That can make storage simple and reduce the need to measure from a larger container, although packet storage takes a different approach than a folding wand and bottle.
TreadLife Fitness describes the formula as non-toxic and odorless. The silicone lubricant is intended for treadmill belts and decks, including routine care for home gym equipment and walking pads.
The 15 in wand is shorter than the 22 in applicators in the two TreadLife alternatives below. It still gives useful reach for many home machines, but you should compare the access area under your ProForm belt before choosing based on wand length alone.
Choose Slick-Stick when measured packets and a 15 in wand fit your routine. Pick a longer applicator if reaching the center of your belt is your main concern.
Icon Health & Fitness: Best for a confirmed motor brush match
- Motor brush kit part 405705
- Works with ProForm 6.0 RT PFTL391150
- Includes one coil spring and two metal springs
- 0.7 x 0.43 in dimensions
This is a replacement part rather than a belt lubricant kit. It fits owners who have confirmed a compatible ProForm model and need the 405705 motor brush kit.
Pros
- Specific ProForm compatibility
- Part number included
- Replacement springs included
Cons
- Not a belt lubricant
- Compatibility must match your model
Icon Health & Fitness is the best choice here when your ProForm treadmill needs the 405705 motor brush kit. This is not a belt lubricant.
It is a model-specific replacement part for machines including the ProForm 6.0 RT with model numbers PFTL391150 and PFTL391151.
The kit includes one coil spring and two metal springs. Its stated dimensions are 0.7 in deep by 0.43 in wide, and the product information identifies the compatible motor brush kit part as 405705.
The compatibility list also includes several ProForm, Crosswalk, Performance 300i and Weslo models. Because motor parts must match the machine, find your exact model name and number before ordering.
A lubricant kit cannot solve every treadmill problem. If the motor brush is worn and your model matches the stated compatibility, this part addresses a different maintenance need from belt lubrication.
Choose Icon Health & Fitness only after confirming the model and part number. It is the wrong pick for routine belt lubrication.
TreadLife Fitness Treadmill Lubrication Kit: Best for broad model coverage
- Three 0.5 oz lubricant applications
- 22 in applicator wand
- Instructions with pictures
- Compatible with Pro-Form and many other treadmill brands
The 22 in wand gives this kit strong reach, while three measured applications suit owners who want a smaller supply for routine care.
Pros
- 22 in wand
- Three measured applications
- Picture-based instructions
Cons
- Fewer applications than the five-use kits
- No motor replacement part
TreadLife Fitness Treadmill Lubrication Kit is the best fit when you want a long wand and a smaller three-session supply. It includes three 0.5 oz lubricant applications, a 22 in applicator wand and instructions with pictures.
The 22 in wand offers the same stated reach as the larger five-application TreadLife kit. That makes it useful for owners who want to spread lubricant under the belt without lifting the treadmill.
TreadLife lists Pro-Form among the compatible treadmill brands, along with NordicTrack, Horizon, Sole, Weslo, Icon Health & Fitness and other brands. The lubricant is 100% silicone, and the instructions are designed to show each step.
Three applications suit a lighter maintenance schedule or a first-time owner who wants a limited supply. If you already know you will lubricate every three months or every 130 miles, the five-application kit offers more sessions.
Choose this kit for broad brand coverage, picture-based directions and a 22 in wand. Choose the five-application version if long-term supply matters more.
Which ProForm treadmill maintenance kit should you choose?
Choose the TreadLife Fitness Treadmill Maintenance Kit if you want the strongest all-around option for recurring belt lubrication. Its five applications and 22 in wand give it the best balance of supply and reach in this group.
Choose Hydra TreadLube if you prefer a bottle with a 16 in applicator and want a compact kit for general treadmill use. Its 100% silicone formula and stated broad compatibility make it a practical belt-care option, but it does not include several maintenance sessions.
Choose Slick-Stick if separate packets keep your care routine simpler. Its 15 in wand is shorter than the 22 in alternatives, so measure the access area under your belt if reach is important.
Choose the TreadLife three-application kit when you want picture-based instructions, three measured applications and a long wand. It is a better match for occasional care than for a heavy-use schedule.
Choose Icon Health & Fitness only for a confirmed motor brush match. A motor brush replacement addresses a different problem from belt lubrication, and the 405705 part should be matched to your exact ProForm model.
How do you use a ProForm treadmill maintenance kit?
Use a ProForm treadmill maintenance kit by turning off and unplugging the machine, checking the manual, applying the recommended amount under the belt, and running the treadmill as directed. Keep lubricant on the belt and deck area only, and avoid applying it to electrical parts.
First, clear dust and debris from around the machine. For a broader upkeep plan, see commercial treadmill maintenance.
A clean surface makes it easier to inspect the belt and reduces the chance of pushing dirt farther under the belt during lubrication.
Next, loosen or lift the belt only as the ProForm instructions allow. Slide the applicator under the belt, apply the stated amount evenly, and avoid over-application.
The TreadLife five-application kit gives a specific routine of about ½ oz on the wand followed by 3 to 5 minutes of belt movement. Other ProForm models may use a different amount or schedule, so the owner manual remains the final guide.
Afterward, wipe away excess lubricant from exposed surfaces. Run the treadmill at a low speed first and check that the belt tracks normally before returning to a full workout.
For a model-specific example, read How to Maintain a ProForm XT 70 Treadmill. You can also learn more about timing in How Often Do Treadmills Need Maintenance?.
What should you check before buying a ProForm treadmill maintenance kit?
Check the maintenance task first, then compare silicone type, applicator reach, number of applications and exact model compatibility. A belt lubricant kit is not interchangeable with a motor brush replacement.
For belt care, look for a treadmill-specific silicone lubricant and an applicator long enough to reach under the belt. The 22 in options offer the longest reach here, while Hydra's 16 in and Slick-Stick's 15 in wands may suit tighter machines or owners who prefer smaller tools.
For recurring maintenance, compare the number of applications. The TreadLife maintenance kit and Slick-Stick each provide five sessions, while the TreadLife lubrication kit provides three and Hydra provides one 2 fluid oz bottle.
For a repair, identify the exact ProForm model and part number. Icon Health & Fitness names the 405705 motor brush kit for the ProForm 6.0 RT and other specified models, but the compatibility list must match your machine.
Don't choose by brand name alone. ProForm has many treadmill models, and a part or maintenance instruction for one machine may not apply to another.
Are ProForm treadmill maintenance kits useful for older machines?
Yes, a ProForm treadmill maintenance kit can help with routine belt care on an older machine. It cannot repair every age-related fault.
Lubrication may support smoother belt movement on a machine that is still sound. It can reduce friction between the belt and deck, which may make daily walks feel more even.
It will not fix a worn belt, a damaged deck or a failing motor. Those parts need their own diagnosis and, in many cases, a separate replacement.
Older treadmills need a closer inspection before you apply lubricant. Look at the belt surface, the edges and the area around the rollers with the machine switched off.
Look for belt damage, fraying, unusual tracking, burning smells or motor problems. Any of those signs should pause routine care until the cause is clear.
Stop using the machine if the issue suggests a safety fault. A belt that slips, grabs or shifts sideways is not something to push through with more lubricant.
Worn brushes, belts, rollers or electronics need separate diagnosis. Each part has a different job, so a general maintenance kit cannot cover every age-related change.
Use a compatible motor brush only when the model and part number match. A close match is not enough for an electrical part that must fit the motor correctly.
The Icon Health & Fitness kit lists part 405705 for the ProForm 6.0 RT and other named models. Check the model name and number in your manual or on the frame label before ordering.
For older machines, start with cleaning and inspection rather than lubricant alone. Removing dust and debris can reveal cracks, loose parts or belt wear.
Keep the inspection simple and repeat it at normal care intervals. A quick look at belt tracking and surface condition tells you more than guessing from sound alone.
If the belt moves smoothly and shows no damage, routine lubrication may be a sensible next step. Use only the amount your manual recommends and run the belt as directed.
If the belt is cracked, frayed or badly tracked, replacement is a better path than lubrication. Adding lubricant to a damaged belt can make tracking worse and waste the product.
Worn or noisy rollers can affect belt movement even when the lubricant supply is fresh. Electrical faults, burning smells or sparking point to a qualified technician rather than a home lubricant kit.
If you are buying a treadmill for an older adult, our guide to the Best Treadmill For Seniors covers access and daily use. Step height, handrail access and a stable walking surface matter for safe daily steps.
A well-maintained older treadmill can still serve light and steady use. The key is honest inspection, correct parts and no rushed fixes.
Verdict: the best ProForm treadmill maintenance kit
The TreadLife Fitness Treadmill Maintenance Kit is the best ProForm treadmill maintenance kit for most owners because it combines five applications with the longest 22 in folding applicator in this group.
That balance of supply and reach makes it the easiest pick for regular home care. Five sessions support a planned schedule, and the wide wand spreads lubricant farther under the belt.
Choose Hydra for a smaller bottle and 16 in wand. It suits owners who want a compact kit for general treadmill use rather than a multi-session supply.
Choose Slick-Stick for individual packets. Separate packets can simplify storage and help you keep each maintenance session measured and tidy.
Choose Icon Health & Fitness for a confirmed 405705 motor brush replacement. That kit solves a repair task, while lubricant kits care for the belt and deck.
Start with the maintenance task, match the product to your ProForm model, and follow the machine manual for application amount and timing.
If the belt is dry, start with lubrication and cleaning. If the motor needs a brush, confirm the exact part number first and order only that part.
Keep a simple record of when you lubricate the belt. A note on the calendar makes it easier to stick to the schedule in your manual.
Store the applicator and lubricant in a dry place after each use. A clean, dry storage spot helps keep the wand ready for the next session.

Frequently asked questions
What is the best ProForm treadmill maintenance kit?
The TreadLife Fitness Treadmill Maintenance Kit is the best ProForm treadmill maintenance kit for most owners who need routine belt lubrication. It includes five lubricant applications, a folding extra-wide 22 in applicator wand and directions.
Confirm your ProForm manual's lubrication instructions before applying any product.
Can I use a universal treadmill lubricant on a ProForm treadmill?
Yes, a silicone lubricant designed for treadmills can suit many ProForm machines, but compatibility depends on the treadmill's maintenance instructions. Hydra says its 100% silicone formula works with most treadmill models, while TreadLife lists Pro-Form among the compatible brands for its lubrication kit.
How often should I lubricate a ProForm treadmill?
TreadLife recommends lubricating under normal use every three months or every 130 miles for its maintenance kit. Your ProForm manual may give a different schedule, so use the machine-specific instructions first and check the belt if you notice unusual friction or noise.
Does a treadmill maintenance kit replace a ProForm motor brush?
No. Lubricant kits care for the walking belt and deck, while a motor brush is a separate replacement part.
The Icon Health & Fitness 405705 kit is designed for specific models such as the ProForm 6.0 RT PFTL391150, so match the model and part number before ordering.
