This is a FINNED style  secondary that allows for more air movement inside the clutch housing, it helps keep the clutches, housing and belts cooler. You will need to cut the cross section part of the clutch housing duct to clear the adjustment nut on the secondary clutch to run this secondary.

This is an all billet construction that is capable of using compression springs. We have different spring rate options available (see menu above). We have many helix angles available (see menu for options). We can also provide custom helix angles if you desire for an additional fee. 

What's Included? 

  • STM Tuner Secondary
  • STM Helix & Secondary Spring
  • STM Secondary Bolt for installation

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.

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

Build time on STM Clutches that are out of stock is roughly 2-3 weeks.
