Shock SZ/SL 7in Comp 4 Reb 10

The BILSTEIN Shock SZ/SL 7-inch Compensator 4 Rebound 10 (part number 33-321752) is a premium monotube shock absorber engineered for off-road suspension systems requiring controlled damping and responsive rebound characteristics. This zinc-plated steel unit delivers the precision control demanded by vehicles operating on uneven terrain, whether for trail recovery, overlanding, or aggressive off-road driving where suspension compliance directly impacts traction and vehicle control.

The shock's monotube design houses a high-pressure gas chamber that maintains consistent damping force across the full range of suspension travel. Compressed length measures 13.15 inches, extending to 20.08 inches at full extension—a 6.93-inch stroke ideal for mid-range suspension lifts and standard travel applications. The 1.81-inch outer diameter accommodates standard shock mounts on aftermarket and OEM suspension brackets. The C4-R10 valve configuration denotes Compression-4 and Rebound-10 characteristics, delivering firm compression damping to support vehicle load while allowing controlled energy release during rebound—critical for maintaining tire contact during rapid terrain transitions and repeated articulation cycles.

This shock suits builders upgrading light-duty and mid-range truck suspensions, Jeep platforms, and recreational four-wheel-drive vehicles seeking predictable damping without excessive stiffness that compromises ride quality on mixed terrain. The zinc plating provides corrosion resistance in dusty, wet, or salt-air environments where unprotected steel would deteriorate. BILSTEIN's reputation in the performance suspension market is built on consistent valve calibration and gas-spring engineering that resists fade during extended trail use or repeated shock cycling.

Proper shock selection requires matching stroke length, mounting diameter, and damping rates to your vehicle's suspension geometry and intended use. This model is sold individually; most installations require a set of four shocks. Verify compatibility with your suspension system's attachment points and travel requirements before ordering.
