LEN PERFORMANCE LS4-11000F Front Track Shock for Select Arctic Cat Snowmobiles

The LEN PERFORMANCE LS4-11000F Front Track Shock is designed for select Arctic Cat snowmobile applications. It features compression and rebound adjustment for tuning suspension performance to trail and mountain riding conditions. Five-click compression adjustment allows settings to be changed easily, while the threaded body provides precise preload adjustability on springed shocks.

Its hardened Chromoly shaft is built to support overall strength and seal longevity, while the powder-coated spring helps reduce corrosion and maintain durability in harsh conditions. The eyelets use a forged aluminum head with premium steel and NBR bushings.
