STM Tuner Secondary Clutch for 2022+ Polaris RZR Pro R

The EVP calibrated STM Tuner Maxxx Secondary is a must-have upgrade to get the absolute most out of any Pro R running a naturally aspirated tune or EVP's P54-330, P54-400, & P54-500 horsepower levels and avoid OEM clutch failure all together.
All new features of the Maxxx include larger rollers and helix, allowing more surface area for the roller to ride on, which reduces pressure and results in less wear and tear. All-billet construction with a finned design that creates more airflow within the clutch housing to help lower belt temperatures and all-around clutch temperatures. Additional features include significantly enhanced belt grip, STM's triple roller design for consistent up/back shifts that are smoother and faster, and improved engine braking, among others.
All EVP STM Tuners come fully assembled and include a secondary spring and helix spec'd to EVP's custom calibrations, as well as hardware kit for installation (additional spring rates and helix angles are available directly through STM).
For best results, EVP recommends running the STM Tuner Secondary Clutch with our variety of EVP-Spec TAPP Primary Clutch Calibrations, AVAILABLE HERE .
