A stock primary clutch on the Polaris RZR XP Turbo S wears from the first ride, and as the rollers, pins and towers go, so do throttle response and belt life. Instead of rebuilding a tired stock clutch, this Billet Primary Clutch Assembly replaces it with a stronger, tighter-tolerance unit that keeps performing on ride 400 like it did on ride four.
Highlights
- Complete billet aluminum construction
- Bigger towers and a wider spider handle more torque than stock
- Chromoly steel spider rollers and pins, the parts that wear first on stock
- Tighter tolerances for better durability and longer belt life
- Works with your OEM clutch spring, secondary clutch and clutch arms
- 2-way bearing: no engine braking
- 3-year manufacturer warranty
Arrives Assembled
The clutch comes fully assembled. Move your OEM spring and arms over, install it on the engine and go. That's a lot quicker than chasing worn parts in a stock clutch one piece at a time.
Built Stronger Than Stock
Machined from billet aluminum, with larger towers and a beefier spider, the assembly is much stronger than the cast factory part. The rollers and pins, usually the first parts to wear in a stock clutch, are made from chromoly steel. Hundreds of miles of hard riding in testing showed it doesn't break down or burn belts the way a worn OEM clutch does.
Choose Your Year
Two versions are offered: 2018-2020 and 2021. Pick the one that matches your model year at checkout.
Upgrade vs. Rebuild
A rebuild replaces worn parts with more stock parts that wear the same way. A billet assembly fixes the root cause with stronger materials and tighter tolerances, and it carries a 3-year warranty, so it's often the better value if your clutch is due for work anyway.
