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.
