EVP Shift-Tek Clutch Kits are well known for their adjustability and versatility technology, both of which play a key role to winning success. Clutching changes are necessary to keep the power in the proper RPM range and with our innovative billet helix design, adjusting the RPMS is a very simple 5-minute job for the racer or enthusiast.

All Shift-Tek kits include our proprietary high-engagement primary spring and torsion secondary spring, our custom geometry weights which improve the overall shift, making them quicker to react and deliver the power. Additionally, as heavier, more aggressive weights are added for high HP applications, generally the engagement RPM will drop which is solved with our primary spring. The billet helix is custom tailored specifically for the 2021RR power level and riding style. Due to the unique design features and adjustability built into each Shift-Tek clutch kit, getting it dialed in for different riding conditions (trail and sand) is a simple task.

Kits Include:

  • Primary Spring
  • Secondary Spring
  • 6 Arm Weights
  • Billet Adjustable Helix with Billet Bearing Housing
  • Non-Marring tip for the OEM belt changing tool
  • Billet Sheave Holder to adjust the Billet Helix Cap
  • Detailed instructions for proper setup and riding styles
