Description

All billet construction capable of using compression springs with different spring rate options. We have many helix angles see menu below. We can also provide custom helix angles to your desire for additional fees.

We also offer the option of a encapsulated helix design that keeps the driven from unloading, opening and going into high gear during breaking and jumping which some racers require.

Can be used along with the stock primary or the STM primary. Best results are acquired when running both the STM primary and STM tuner together. 

Comes with a belt removal tool and uses stock bolt for installation.

KEEP IN MIND WE CAN ONLY GET YOU CLOSE WITH SET UP. Everyone’s riding style is different so it’s up to the customer to do the fine tuning!
