Bilstein M 7100 shock absorbers are filled with the technology perfected over 3 decades of off-road dominance. Bilstein's monotube gas pressure design maximizes heat dissipation for increased shock life, and decreases oil foaming to prevent performance loss while under extreme working conditions. Available for lifted truck, custom truck, rock crawling and off-road racing applications.

Bilstein SZ Series shock absorbers are designed for, but not limited to, Modified and Late Models. The 46mm monotube steel body design allows for conversion to coilover applications, when necessary. It is a sealed unit that you can expect Bilstein's famous consistent, fade-free performance from. The body is plated for extreme durability and rapid heat dissipation. There are 26 standard digressive valvings, as well as custom valving available.

H&R 60mm I.D. (inside diameter) Race Springs, Free Length: 180mm. Race Springs are for off-road use only, they are made of extremly solid steel, which leads to a reduction of weight and more travel for a given spring rate than competitive springs made of usual spring steel.

H&R 2.5" I.D. (inside diameter) Race Springs, Free Length: 10". Race Springs are for off-road use only, they are made of extremly solid steel, which leads to a reduction of weight and more travel for a given spring rate than competitive springs made of usual spring steel.
