STM Gen 1 Tuner Opposite Rotation Secondary Can-Am Long Post

Calculated at Checkout


This is for machines with the clutches on the Right side of the machine only (under your right foot when sitting on the machine). 
All billet construction is capable of using compression springs with different spring rate options. We have many helix angles available (see list above). We can also provide custom helix angles if you desire, for an additional fee.
We also offer the option of a 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

Choose a helix angle - The most popular helix is the 40/45°. It’s a good all-around helix. We found it worked the best for the average to aggressive trail rider.

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. If you are installing this with a stock primary clutch or the new STM Rage Gen 2 with the smaller 1-way or 2-way bearing-choose 3 shims. If you are installing this with an older STM primary clutch with the larger 2-way bearing-choose 5 shims. 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 spring– The most popular spring for the stock Outlander 400 & 450 is the PS7 yellow. This spring works well for most average to aggressive trail riders.

Comes with a belt removal tool and bolt for installation.

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