Len Performance Ski Shocks, Ski-Doo MXZ 129 / Renegade 137 / Backcountry 146 / Summit 600 SP 2015–2023 (Left & Right, 54-80001-1LH / RH)

Product details

Len Performance LS8-80001-1LH / -1RH rebuildable ski shocks for Ski-Doo trail and crossover sleds: 2015–2022 MXZ 129 (Sport, TNT, Blizzard, X, X-RS, Iron Dog), 2015–2023 Renegade 137 (Sport, Adrenaline, Enduro, X, X-RS), 2016–2018 Renegade Backcountry 146 and the 2015–2021 Summit 600 SP 146 / Summit 600 Sport. They are direct replacements for the factory front (ski) shocks. Sold each; choose Left or Right, or add one of each for a complete front end. At $566.95 each, it is A2D's value pick for a rebuildable, adjustable reservoir ski shock: clicker adjustment, a reservoir and a serviceable design without the cost of a race-level shock.

The ski shocks set how the front end reacts to trail chop, how hard the skis bite in a corner and how much the sled dives on the brakes. These coil-over reservoir shocks have 5-click compression and 5-click rebound adjustment plus a threaded body with locking preload rings, so the front end can be set for rider weight and trail conditions instead of running fixed factory valving. This -1 version has 10 mm eyelets with axle spacers included to fit the 8 mm mounts, and supersedes the earlier LS8-80001LH / RH (8 mm eyelets only), which are no longer available.

Fitment. Left and right shocks are side-specific because of the reservoir orientation; order the side you need (Len Performance sells the pair as kit LS8-80001-1K). Matching Len Performance track shocks: 54-80001F front track and 54-80001R rear track on the MXZ 129; 54-80000F front track and 54-80003R rear track on the Renegade 137; 54-80000F and 54-80000R on the Renegade Backcountry 146 and Summit 600 SP 146. Platform: Ski-Doo REV-XS (2015–2016 and 900 ACE / 1200 4-TEC models through 2018) and REV Gen4 (2017 and later 850 E-TEC and 600R E-TEC models).

Specifications

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.

Len Performance rebuild kits are available, so the shock can be serviced or re-valved rather than replaced.
