STM Tuner Secondary for Polaris Pro-XP and Turbo R and Pro S
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. 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.
Features:
- Comes with bolt for installation
