⚙️ LOOKING TO SHED ROTATIONAL WEIGHT? Check out our Lightweight Secondary Clutch Helix (SKU: 05-TSS-4C)—precision CNC-pocketed to reduce rotating mass by nearly 20%!

SKU: 05-TSS-4

Primary Application: Polaris Patriot 850 short track, trail, and crossover snowmobiles equipped with TSS-04 secondary clutches.

Maximize trail acceleration, eliminate power-robbing belt slippage, and increase top-end lake speed on your Polaris Patriot 850 with the Bikeman Performance Custom Secondary Clutch Helix. Purpose-built for aggressive trail riding and high-speed lake runs, this precision-machined helix optimizes secondary clutch shift geometry to convert 850 engine horsepower into maximum forward track momentum.

Stock secondary helix ramps compromise between comfort and broad utility, leaving acceleration and backshift response on the table. Our proprietary ramp profile loads the secondary sheaves aggressively to maintain firm side-pressure against the drive belt, preventing belt slip and heat build-up under hard acceleration. Expect razor-sharp backshifting when chopping the throttle into tight corners and relentless, hard-pulling upshift acceleration across open lakes and long trail straights.

Key Performance Features

  • Aggressive Trail Shift Geometry: Proprietary ramp angle profile loads the secondary clutch harder to maximize belt pinch and forward acceleration.
  • Instant Corner-to-Corner Backshift: Forces immediate secondary downshifting when letting off the throttle, providing instant throttle snap and power delivery on corner exits.
  • Increased Mid-Range & Top-End Speed: Allows the secondary clutch to shift out completely without belt slippage, delivering significant speed gains on wide-open pulls.
  • Reduced Clutch Heat & Belt Glazing: Consistent belt pinch eliminates power-wasting friction, drastically lowering secondary operating temperatures and extending drive belt life.
  • CNC Billet Aluminum Construction: Precision-machined from aircraft-grade billet aluminum to deliver extreme dimensional stability and long-term durability under heavy trail abuse.

Critical Fitment & Roller Compatibility Note

⚠️ IMPORTANT OEM CLUTCH ROLLER FITMENT NOTE: This helix requires small secondary clutch rollers for bind-free operation.

Polaris introduced a larger OEM secondary roller on select models beginning in the 2021 model year. These larger factory rollers are NOT compatible with this helix profile. If your Patriot 850 is equipped with the larger factory rollers, you must install our Small Secondary Clutch Rollers (SKU: TP-460079K) for proper fitment and operation.
