Len Performance was developed in the heart of the American Midwest by riders that are passionate about the powersports industry and the machines they ride. We set off to develop a line of high performance shocks that we could rely on whether we were on the trails in Minnesota or in the backcountry of Wyoming. We knew what we wanted, a rebuildable reservoir shock that is tunable, adjustable but also user friendly.

Len Snowmobile Ski Shocks feature a user friendly intuitive design and come standard with a 5 click rebound adjustment for increased adaptability to any riders experience level in any condition!
The springs are powder coated to reduce corrosion, increase durability and ensure continued strength. The hardened chromoly shaft increases overall strength and seal longevity. Serviceable design increases the lifespan of our shocks and ensures consistent performance for many years to come.
Annodized aluminum finned reservoir offers added surface area for superior cooling, while also increasing strength. Len Shocks all come standard with a 5 stage compression adjustment. User friendly intuitive design features 5 click compression adjustments for seamless adaptation.
All springed shocks feature a threaded body for ultimate preload adjustability. Anodized dual ring locking adjusters make it easy to adjust your preload but ensure they stay set once you have them adjusted to your preferred settings.
