These performance struts are designed to deliver a lower ride height without sacrificing ride quality giving your vehicle a sleek stance and sharper handling dynamics. From tight turns to daily driving the M1's monotube design and digressive valving react instantly to surface changes for a stable composed ride.

Self-adjusting deflective-disc valving ensures that rebound and compression stay balanced even on unpredictable surfaces. The ride height is fully adjustable using the notched body design allowing precise perch placement for dialing in the perfect drop. An 18mm chromed and polished rod and vulcanized natural rubber bushings add long-term durability and vibration control. Clean Looks. Confident Ride.
