This is a large finned style billet secondary that creates added cooling in the stock belt housing. It is all billet construction and capable of using compression springs with different spring rate options available. We have many helix angles see menu for available options. We can also provide custom helix angles to your desire for additional fees.

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.
Choose a helix angle - The most popular helix is the 45º. It is a good all-around helix. We found that is worked the best for the average to aggressive trail rider
