LEN PERFORMANCE LS8-50000 Ski Shock for Select Polaris Models

The LEN PERFORMANCE LS8-50000 ski shock is designed for select Polaris snowmobile applications, including specified Switchback, Voyageur, Rush Pro-S, and Switchback XCR models from 2016 through 2019. Its adjustable design helps riders fine-tune suspension performance for changing trail and mountain conditions.

The shock features five-click compression adjustment for convenient setting changes on the trail or mountain. Anodized dual-ring locking adjusters provide preload adjustability while helping maintain the selected setting. The hardened Chromoly shaft is designed to increase overall strength and seal longevity, while the forged aluminum eyelet head uses premium steel and NBR bushings.

All ski shocks feature compression and rebound adjustment. Spring-equipped shocks use a threaded body for preload adjustment, and the springs are powder coated to help reduce corrosion and support durability in demanding conditions. LEN PERFORMANCE also offers rebuild kits and replacement parts for servicing and custom valving. This shock is sold individually.

Fitment includes the 2017 Polaris 600 Switchback SP 144-inch, 2017 Polaris 800 Switchback Adventure 137-inch, 2017 Polaris 600 Voyageur 144-inch, 2016 Polaris 800 Switchback Adventure 137-inch, 2018 Polaris 600 Switchback SP 144-inch, 2018 Polaris 800 Switchback Adventure 137-inch, 2019 Polaris 850 Rush Pro-S 120-inch, 2019 Polaris 850 Switchback Pro-S 137-inch, 2019 Polaris 850 Switchback XCR 136-inch, and 2019 Polaris 800 Rush Pro-S 120-inch models.
