Description
A primary spring directly controls when your snowmobile’s CVT engages and how it performs across the RPM band—getting it right means the difference between sluggish acceleration and crisp, predictable power delivery. The SLP 40-67 uses premium chrome-silicone wire with shot-peening to eliminate the sagging and fatigue that plague stock springs, giving you consistent engagement characteristics mile after mile. If you’re tuning your drive system for peak performance or simply tired of replacing worn springs, this is the upgrade that actually delivers measurable results.
