Product details
Len Performance LS8-50002 rebuildable ski shock for the Polaris AXYS 600 / 800 Pro RMK 155 / 163 / 174 (including Pro RMK LE) 2016–2018 and the AXYS 800 / 850 SKS 146 / 155, 2016–2021. One part number fits either side. At $522.95 each, it is A2D's value pick for a rebuildable, adjustable reservoir mountain ski shock: clicker adjustment, a reservoir and a serviceable design without the cost of a race-level shock.
On the AXYS RMK and SKS the ski shocks control how the front end settles on a sidehill and how it takes re-entries and stump hits in the trees. This coil-over reservoir shock has 5-click compression and 5-click rebound adjustment and a threaded body with locking preload rings, so ski pressure can be set for rider weight and snow conditions instead of running fixed factory valving.
Fitment. Sold each; order two for a pair (Len Performance sells the pair as kit LS8-50002K). Matching Len Performance track shocks for the SKS 146 skid are the 54-50000F front track shock and 54-50000R rear track shock. Chassis: Polaris AXYS.

Ordering and installation. Sold each. Ships from stock at our Anchorage shop, or from our distributor's Boise, Idaho warehouse when not on the shelf. In-store pickup is available at checkout. Installation and shock setup are available at A2D Motorsports; call (907) 306-3062 to schedule. Len Performance rebuild kits are available, so the shock can be serviced or re-valved rather than replaced.
