STM Tuner Secondary Polaris Gen1 (No Spring, Helix - With Engine Brake)

STM Tuner Secondary Polaris Gen1 (No Spring, Helix - With Engine Brake)


All billet construction capable of using compression springs with adjustable spring rate options. We have many helix angles, see below. We can also provide custom multiple helix angles to your desire for additional fees.

The dual roller option creates a very consistent smooth up shift and backshift. The encapsulated helix design keeps the driven from unloading, opening and going into high gear during downshifting, breaking and jumping. The use of the helix body to support the moveable sheave instead of towers keeps the whole assembly concentric and centered without twisting while under load. This is a tremendous upgrade over the stock driven.

Can be used along with the stock primary or the STM Rage dual speed primary.

When ordering use this guide to help you pick options  

Choose a model – Let us know what you have RZR pre 2010, RZR 2011-2013, or XP

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 2011-2013 choose 3 shims,  XP choose 2 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 45deg. It’s a good all-around helix we found worked the best for the 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.

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

KEEP IN MIND WE CAN ONLY GET YOU CLOSE WITH SET UP every ones riding style is different so it’s up to the customer to do the fine tuning!
