Polaris TSS-04 Secondary Clutch Spring Roller Bearing // SKU: 05-RB-301

Eliminate spring torsional binding and unlock smooth, consistent clutch shifting with the Bikeman Performance Polaris TSS-04 Secondary Roller Bearing. As a TEAM TSS-04 secondary clutch shifts out toward its maximum overdrive ratio, the internal secondary spring is forced to twist as it compresses. Without a low-friction bearing, this torsional force causes the spring coils to bind against the clutch cup—robbing horsepower, causing erratic RPM fluctuation, and degrading backshift response.

This high-precision thrust roller bearing sits directly under the secondary clutch spring, allowing the spring to rotate freely throughout its entire compression cycle. The result is seamless full-shift performance, smoother throttle transitions, and reliable, instant backshifting when working technical terrain.

Key Performance Features

• Prevents Spring Coil Binding: Allows the secondary spring to twist freely during full shift-up, completely eliminating internal coil friction and binding against the clutch cup.

• Smoother Shift-Out & Backshifting: Maintains consistent belt side-pressure for smooth, linear shift-up and rapid, predictable backshifting during on/off throttle riding.

• Holds Target Shift RPM: Eliminates erratic RPM drops and top-end power fading caused by twisted, bound secondary springs.

• Extends Clutch Component Life: Reduces heat, torsional stress, and premature fatigue on your secondary clutch spring and sliding sheaves.
