UHMW Poly Rear Idler for Snowmobiles

Upgrade your snowmobile's performance with our premium UHMW Poly Rear Idler, engineered for durability and efficiency in the toughest winter conditions at an affordable price over billet options. Crafted from ultra-high-molecular-weight polyethylene (UHMW-PE), this rear idler offers exceptional strength, low friction, and superior resistance to wear, ensuring smooth track operation and extended lifespan.

Key Features:

• High-Durability UHMW-PE Construction: Resists abrasion and impact, outperforming traditional materials in harsh snow and ice environments.
• Low-Friction Design: Reduces drag on the track, improving fuel efficiency and enhancing acceleration for a smoother ride.
• Cold-Weather Resilience: Maintains flexibility and performance in sub-zero temperatures, preventing cracking or deformation.
• Precision Fit: Designed to seamlessly integrate with most snowmobile models, ensuring easy installation and reliable operation.
• Lightweight Performance: Lighter than metal alternatives, reducing overall sled weight for better handling and speed.

Benefits:

• Enhances track longevity by minimizing wear and tear.
• Improves ride quality with reduced vibration and noise.
• Built to withstand extreme conditions, from deep powder to hard-packed trails.

Rear Idler Axle Compatibility Guide:

Our UHMW Poly Rear Idler wheels are available exclusively in a 9-inch size. To ensure a perfect fit with your snowmobile, select the appropriate axle by calculating the offset based on your stock wheel size. Follow these steps to determine the correct axle offset:

1. Measure the diameter of your stock idler wheel.
2. Subtract the stock wheel size from the 9-inch replacement wheel size.
3. Divide the difference by 2 to find the required offset (split evenly between upward and forward adjustments).

Examples:

• For a 7.25-inch stock Polaris wheel:
  9" - 7.25" = 1.75"
  1.75" ÷ 2 = 1-inch offset axle (1" upward and 1" forward).

• For an 8-inch stock Ski Doo wheel:
  9" - 8" = 1"
  1" ÷ 2 = 0.5-inch offset axle (0.5" upward and 0.5" forward).

Perfect for avid snowmobilers and competitive riders, the UHMW Poly Rear Idler delivers unmatched reliability and performance. Conquer the trails with confidence this winter!

6005 wheel bearing (upper idler wheel)

The bearings for the lynx upper idlers do not fit.

TKI has produced a bushing for the bearing so it will fit.

IF YOU HAVE A LYNX, MAKE SURE YOU SELECT THAT OPTION.

6205 wheel bearing (offset axle)

6304 wheel bearing (stock axle)

Changes in OEM rails have made the axle window less durable and with aggressive riding they are starting to fail and deform.

Our made in the USA Billet Rail brace stiffener mounts over the OEM rail and helps prevent axle window deformation and stiffens the back of the rail to prevent rail bending.

THE TKI CNC RAIL BRACE STIFFENER IS DESIGNED FOR USE WITH TKI CNC AXLES ONLY.  OEM WHEELS CAN BE ONLY USED WITH A TKI CNC STRAIGHT AXLE WITH 20MM BEARINGS. 

****NOT COMPATIBLE WITH LYNX RAILS
