BIL Motorsport Series Shocks

Bilstein SZ dry kits are partially assembled (no valving, oil or gas), smooth body monotube shock absorbers that are intended for motorsports applications. These kits allow shock absorber tuners the versatility to build to their unique needs using the primary components of the SZ shock absorber. Assembly requires special equipment and is not considered "racer rebuildable." SZ dry kits are geared towards shock absorber tuners looking for a premium non-rebuildable design that provides custom tuning capability. Bilstein SZ shock absorbers feature a 46mm piston, steel construction and smooth body designed for motorsports applications. These shock absorbers are available in a variety of lengths and standard digressive valve settings that utilize proprietary spring steel valve discs and can be converted to a coilover design (kit sold separately). They are also available as dry kits (partially assembled wtih no valving or gas) that are geared towards giving tuners the versatility to build to their unique needs. SZ shock absorbers are ideal for racers whose sanctioning rules do not allow or require rebuild capability. SZ -Shock Absorber.
