* This Rear Shock is a direct stock replacement for this application.

* OEM standard shocks, even with the latest improvements in shaft scraper technologies, shock performance erodes when ice/water get past the scraper/seals into the shock oil.

* Replacing your OEM shocks per-season will allow you to stay out and ride with optimal performance from your shocks instead of having to replace your shocks mid-season.
