RPM P90X Secondary Butter Shift Washers

Eliminate harsh shifting and unwanted clutch chatter! The RPM SXS P90X Secondary Clutch "Butter Shift" Washer Kit is engineered specifically across P90X-equipped Polaris platforms to deliver buttery-smooth shift transitions and optimize overall power delivery.

This kit features two precision-stacked friction washers installed directly inside the secondary clutch helix. By creating a slick, ultra-low-friction pivot surface for the secondary spring, these washers allow the spring to compress and rotate freely without binding or twisting against the helix face.

This simple yet highly effective upgrade drastically reduces internal spring friction, eliminates annoying harmonic clutch noise, and ensures maximum, consistent belt clamping force—helping prevent belt slippage when higher spring tension is demanded on high-horsepower setups!

Features:

  • "Butter-Smooth" Shifting: Allows the secondary clutch spring to rotate cleanly without binding during aggressive shift cycles.

  • Reduces Harmonic Noise: Minimizes spring chatter, resonance, and clutch harmonic vibration.

  • Prevents Belt Slippage: Maintains consistent spring force and belt bite under heavy load and sudden throttle hits.

  • Heavy-Duty Low-Friction Material: Built to withstand intense clutch temperatures, heavy rotational stress, and belt dust.

  • Direct Drop-In Upgrade: Installs cleanly inside the P90X secondary clutch helix during routine maintenance, tuning, or spring swaps.

  • (2) RPM SXS Precision P90X Secondary Clutch "Butter Shift" Helix Washers
