Polaris Sportsman 800 Billet STM Secondary Clutch 05'-14' - STM Powersports

STM Gen 2 billet tuner secondary is a 3 roller secondary that offers an extremely smooth up shift with a very quick back shift. This secondary is tune-able with many helix and spring options available.  

The NEW TRIPLE roller option with a 1.25" diameter roller creates a very consistent smooth up shift and back shift with improved roller wear. This latest design creates a huge improvement in engine braking compared to our dual roller tuner. All billet construction capable of using compression springs with different spring rate options. We have many helix angles-see menu above. We can also provide custom helix angles if you desire for an additional fee.

We also offer the option of an 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. 

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