Len Performance Rear Shock (LU4-50000)

Len Performance Reservoir Shocks are engineered with the rider in mind and come ready to mount out of the box with preload adjustability. Utility machine shocks feature 5-click compression and 5-click rebound adjustments, while sport machine shocks are equipped with 3-step high-speed, 8-step low-speed compression, and 8-step rebound adjustments. This wide range of tunability allows riders to fine-tune their suspension for any terrain or riding style. The aluminum reservoirs feature a finned cooling system to reduce heat build-up, ensuring consistent performance and longer shock life under the harshest conditions. Every component is crafted from high-grade materials, including an aluminum head, with all aluminum parts anodized for superior durability and corrosion resistance. With rider experience as the top priority, Len Performance also provides a nationwide service center network to keep shocks performing at their best and riders on the trail longer.
