Bilstein G Series Shock Absorbers are designed for, but not limited to, Stock Cars, IMCA/UMP Modified, Midgets, Mini-Sprints, Modified Lites and Dwarf Cars. The 36mm monotube steel body design allows for conversion to coilover applications, when necessary and is available in 6" and 7" stroke lengths. It is a sealed unit that you can expect Bilstein's famous consistent, fade-free performance from. The design allows for low rod pressure, reducing the gas spring effect, and making it much easier to tune spring/valving rates. It's a lightweight shock that won't weigh heavily on your wallet!
