 Product Description

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

 

Product Description

The NEW TRIPLE roller option with a 1.25" diameter roller creates a very consistent smooth upshift and backshift 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. 

When ordering use this guide to help you pick options    

Number of shims – The amount of shims we install will determine your belt deflection or how tight the belt will be between your primary and driven clutch. Keep in mind we are setting the deflection for a stock belt, for an RZR pre-2010 choose 1 shim, RZR 2011-2015 choose 3 shims, XP choose 3 shims. Keep in mind the more shims you add the looser the belt-less shims tighter belt. NOTE: You want to have your belt as tight as possible without the bike creeping forward while in gear at idle.

Choose a helix angle - The most popular helix is the 45°. It’s a good all-around helix we've foundthat works the best for average to aggressive trail rider.

Choose a spring– The most popular spring is the PS13 gold. This spring works well for most average to aggressive trail riders. If you have a turbo choose the KSS12 blue spring. 

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

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!
