SKU: 05-TP155-222

Primary Application: Polaris Patriot 850, 9R, and Patriot Boost short track, trail, and crossover snowmobiles equipped with TSS-06 secondary clutches.

Elevate secondary clutch responsiveness and maintain your target shift RPM with the Bikeman Performance 155-222 Secondary Clutch Spring for Polaris Patriot snowmobiles. Developed through extensive R&D and field testing on high-speed trail systems, this spring delivers precise side-pressure against secondary sheaves to optimize belt squeeze, eliminate slippage, and sharpen backshifting.

Manufactured from premium, high-tensile spring steel, it resists heat sag and rate degradation through extreme operational stress. Featuring a 155 lb initial load and a 222 lb finish load, this spring rate profile provides the exact force curve required for crisp, linear shift-out and instantaneous backshift response when working aggressive trail corners and hard acceleration runs.

Key Performance Features

• Trail & Crossover Patriot Calibration: Specially engineered to complement the horsepower curve and clutching needs of short-track, trail, and crossover Patriot 850, 9R, and Boost models.
• 155-222 Spring Rate Profile: 155 lb initial load delivers targeted initial preload, while the 222 lb finish load maximizes belt grip and accelerates backshifting coming out of trail corners.
