⚙️ LOOKING FOR THE LIGHTWEIGHT VERSION? Check out our Lightweight Custom Long Track / Mountain Helix (SKU: 05-TSS-1C) to shed nearly 18% of rotational mass for faster throttle pickup!
SKU: 05-TSS-1
Primary Application: Polaris RMK, PRO-RMK, Khaos, SKS, and Switchback Assault models equipped with 2.0" or deeper lug tracks.
Maximize track speed, eliminate deep powder RPM drag, and hold your engine in its peak powerband on steep climbs with the Bikeman Performance Custom Long Track / Mountain Helix for Polaris Patriot 850 snowmobiles. Stock secondary helix profiles cause the secondary clutch to shift out too quickly in heavy snow or steep mountain terrain—resulting in powerband bog, excessive belt heat, and lost track speed.
Precision CNC-cut in-house, this helix features a multi-angle ramp profile designed specifically for long-track drag, high elevation, and deep powder track resistance. By keeping optimal side-pressure on the drive belt, it provides instant backshift when modulating the throttle while boondocking or sidehilling, ensuring immediate power delivery without trenching or slipping.
Key Performance Features
- Mountain & Deep Powder Ramp Profile: Engineered for heavy track resistance, steep technical climbs, and high-load long-track setups (2.0"+ lugs).
- Lightning-Fast Powder Backshift: Instantly downshifts when cycling the throttle in technical terrain, putting peak shift RPM back on tap without lag.
- Prevents Track Speed Drop & Bog: Holds proper secondary sheave pressure to prevent premature upshifting, keeping the Patriot 850 engine locked in its ideal horsepower 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 Kit Component: The exact custom mountain helix included in the Bikeman Stage 2 Long Track / Mountain Clutch Kit (SKU: 06-37-302).
Product Specifications & Fitment Rules
- SKU: 05-TSS-1
- Engine Fitment: Polaris Patriot 850 (AXYS & Matryx Chassis)
- Compatible Sled Models: Fits all Polaris RMK, PRO-RMK, Khaos, SKS 146 / 155, and Switchback Assault models equipped with 2.0" or deeper lug tracks.
- CRITICAL LUG DEPTH RULE: ANY Polaris Patriot 850 running a 2.0" or deeper lug track MUST use this helix regardless of riding elevation or chassis name. Sleds running tracks under 1.75" lug depth MUST use the Custom Short Track Helix (SKU: 05-TSS-4).
- Clutch Compatibility: Fits TSS-04 style secondary driven clutches. (Note: 2021+ models equipped with updated secondary clutch rollers require Bikeman Small Secondary Rollers for proper dual-cut clearance).
