Shock Features: Len Performance reservoir snowmobile shocks are designed and built with the focus on the rider. Their shocks are ready to mount out of the box with preload adjustability and feature 5 click compression and rebound adjustments for front ski shocks and 5 click compression adjustment on all track shocks. These range of adjustments help the rider easily fine tune their suspension to whatever their needs may be. Their aluminum reservoirs feature a finned cooling system which helps prevent performance robing temperatures and increases longevity and performance under the harshest conditions. They use only high-grade materials including aluminum head and anodize all aluminum components for increased durability and corrosion resistance. With their focus on rider experience we have a network of rebuilders to help keep you on the trail.
