Whether you're running an OEM, TAPP, or STM primary clutch, the STM Tuner Secondary is a must-have addition to get the absolute most out of any power level. STM Tuner Secondaries are all-billet construction and feature a finned design that creates more airflow within the clutch housing to help lower belt 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.
