The 5100 Series offers traditional Bilstein technology with applications for lifted trucks, Jeeps and prerunners. They are designed for specific manufactured lift kits utilizing the stock O.E.M. mounting configuration.

5100 Series shocks feature Bilstein's single-tube, high gas pressure design for consistent fade-free performance and long life. Bilstein's patented digressive self-adjusting valving delivers improved damping control and a smooth ride on all road surfaces at any speed.
•Self-adjusting deflecting disc valving
•High-flow piston reduces harshness
•Independent rebound & Compression Tuning
•Larger Working Piston Area for Exact Damping
•Superior Control for Large Diameter Tires

All Bilstein gas pressure struts/inserts and gas pressure shock absorbers operate on the same principle. They are manufactured with the rod pointing down into the strut tube, thereby utilizing the thicker, stouter body portion of the shock absorber to dissipate side loads. Consequently, due to the increased diameter and surface of the pressure tube, the Bilstein gas pressure strut/insert or shock is better suited to take increased side loads when compared with the conventional version.

Additional advantages, based on development strongly influenced by the motorsport industry, include greater stability, better road handling, and accurate steering. This combined with extremely high quality manufacturing and materials, means Bilsteins will last approximately four times as long as Original Equipment.
