Moose Offroad Polaris Primary Clutch Spring
The Moose Offroad Polaris Primary Clutch Spring is a high‑performance replacement spring designed to fine‑tune engine engagement, RPM behavior, and clutching characteristics on select Polaris ATVs and UTVs. Made from heavy‑duty spring steel and engineered to match Polaris‑specified spring rates, this spring installs in the primary clutch where it controls when the clutch begins to engage and how quickly it ramps up, giving riders more predictable throttle response and better low‑end pull or top‑end efficiency depending on the selected rate.
Each spring in the Moose Offroad Polaris line carries a distinct color‑coded rate (such as 42/180, 42/220, 75/155, etc.), allowing users to “tune with a spring” for conditions like mud, dunes, or trail riding. The spring fits OEM‑style primary clutch assemblies so it can be swapped in with standard clutch‑puller tools, making it an easy upgrade for riders who want to firm up engagement, raise stall speed, or better match a modified clutch or heavier belt.
