The Ultra Ride Adjustable Shocks feature deflective disc valving which increases compression sensitivity, creating the ultimate street rod valving for non coil-over suspensions. The aluminum shock body is smooth, sleek and has a show appearance achieved through state-of-the-art machining. Each Ultra Ride shock features a 18-position rebound valving adjuster to control different suspension styles. The 5/8'' centerless ground, hard chrome plated, solid piston rod eliminated piston rod flex and increases valving consistency. The three-step sealing uses advanced aerospace material to eliminate the possibility of leaking and a secondary wiper seal stops road grime from getting to the seals. Each shock is 100% dyno tested and serialized to ensure consistency in production and performance.
