Description

Your snowmobile's primary clutch performance hinges on spring quality—a worn or undersized spring will cost you engagement consistency and peak RPM efficiency. The SLP 40-73 Primary Spring delivers precision engagement tuning through shot-peened chrome-silicone construction, eliminating the power loss and erratic feel that comes with degraded OEM springs. Whether you're chasing consistent track performance or reliable trail riding, this direct bolt-on upgrade restores the responsive drive feel your sled demands.

  • Chrome-silicone wire construction
  • Shot-peened for durability
  • Optimized drive engagement
  • Peak RPM tuning
  • Resists sagging, breakage
  • Bolt-on installation
  • MPN: 40-73
