⚙️ LOOKING TO SHED ROTATIONAL WEIGHT? Check out our Lightweight Secondary Clutch Helix (SKU: 05-TSS-6C)—precision CNC-pocketed to reduce rotating mass by nearly 20%!

SKU: 05-TSS-6

Primary Application: All Polaris Patriot 9R snowmobiles (Trail, Crossover, and Mountain models) equipped with TSS-6 secondary clutches.

Maximize track speed, eliminate power-robbing belt slip, and unleash the full potential of your high-revving 899cc engine with the Bikeman Performance Custom Secondary Clutch Helix for Polaris Patriot 9R platforms. Engineered for both high-traction low-altitude trail setups and steep backcountry powder climbs, this custom-machined helix optimizes secondary shift geometry to transfer raw engine power directly to the track.

Calibrated specifically to complement the ultra-lightweight rotating assembly and quick throttle response of the Patriot 9R engine, this helix profile delivers aggressive sheave side-pressure to prevent belt glazing and RPM bogging under heavy load. The result is instantaneous backshifting when chopping the throttle in tight technical trees or trail corners, paired with hard-pulling, sustained shift RPM across wide-open pulls.

Key Performance Features

  • Universal 9R Performance Calibration: Optimized ramp geometry engineered to maximize acceleration and track speed across both mountain deep-snow and trail/crossover setups.
  • Instant Throttle Backshift: Forces rapid secondary downshifting during quick on/off throttle transitions, keeping the high-revving 9R engine locked directly in its peak powerband.
  • Sustained Target Shift RPM: Prevents RPM drop and engine bogging under high-resistance track loads on steep mountain ascents and dense trail snow.
  • Eliminates Belt Slippage & Excess Heat: Delivers positive drive belt squeeze throughout the full shift cycle, drastically reducing clutch operating temperatures and extending drive belt life.
  • Billet Aluminum Construction: CNC-machined from high-strength billet aluminum to withstand extreme thermal expansion, continuous twisting forces, and severe riding conditions.

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 2021. These larger factory rollers are NOT compatible with this helix profile. If your 9R is equipped with the larger factory rollers, you must install our Small Secondary Clutch Rollers (SKU: TP-460079K) for proper fitment and operation.

Vehicle Fitment & Compatibility
