We have designed the 2-Step Launch Control to work with stock clutching, however, higher RPM engagement is achieved by upgrading your clutching to either our Shift-Tek Silver Spring or our Shift-Tek Essential Clutch Kit that includes the high engagement spring and notched weights.

Furthermore, if you already have upgraded clutching (STM for example) you only need to purchase the programming at the higher RPM Engagement.
