Bilstein SZ Series 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 Series shock absorber. Assembly requires special equipment and is not considered "racer rebuildable." SZ Series dry kits are geared towards shock absorber tuners looking for a premium non-rebuildable design that provides custom tuning capability.
