05-TSS-1 Mountain Helix for Polaris Patriot 850 // SKU: 05-TSS-1

Maximize track speed, eliminate deep powder RPM drag, and hold your engine in peak powerband on steep climbs with the Bikeman Performance 05-TSS-1 Mountain Helix for Polaris Patriot 850 snowmobiles. Stock secondary helix profiles are cut as a general compromise, often causing the secondary clutch to shift out too quickly in heavy, wet snow or steep mountain terrain—resulting in powerband bog, excessive belt heat, and lost track speed.

Precision CNC-cut in-house, the 05-TSS-1 features a custom-engineered multi-angle ramp profile designed specifically for high elevation, deep snow resistance, and aggressive mountain riding. By keeping optimal side-pressure on the drive belt, this helix provides instant backshift when on and off the throttle while tree riding or sidehilling, ensuring immediate power delivery without trenching or slipping.

Key Performance Features

  • Mountain-Specific Ramp Profile: Engineered for deep powder, steep technical climbs, and high-load track resistance on long-track mountain machines.

  • Lightning-Fast Deep Snow Backshift: Instantly downshifts when modulating the throttle in technical terrain, putting peak shift RPM back on tap without hesitation.

  • Prevents Track Speed Drop & Bog: Holds proper secondary sheave pressure to prevent premature upshifting, keeping the Patriot 850 engine locked in its ideal horsepower RPM range.

  • Dramatically Reduces Belt Heat: Eliminates power-robbing belt slippage under heavy snow load, keeping clutch sheaves cool and extending drive belt life.

  • Stage 2 Mountain Component: The exact custom mountain helix included in Bikeman’s All Elevation / Mountain Stage 2 SNYPR Clutch Kits.
