Shock SZ/SL 7in Comp 4 Reb 15

The BILSTEIN Shock SZ/SL 7in Comp 4 Reb 15 is a monotube shock absorber engineered for demanding off-road and heavy-duty vehicle applications. This 7-inch compensator shock combines precision damping control with robust construction, delivering responsive handling over rough terrain and extended suspension travel. The C4-R15 valve configuration provides four-stage compression and fifteen-stage rebound adjustment, allowing fine-tuning of suspension behavior across varied driving conditions.

With a compressed length of 13.15 inches and extended length of 20.08 inches, this shock delivers 6.93 inches of usable stroke—critical for vehicles tackling rocky trails, water crossings, and high-speed desert running. The 1.81-inch outer diameter fits standard mounting locations on mid-size and full-size trucks and SUVs. Steel construction with zinc plating resists corrosion from mud, salt spray, and moisture exposure typical of backcountry environments. The monotube design isolates the piston rod from the main fluid chamber, reducing heat buildup during extended off-road use and improving consistency over multiple cycles.

This shock suits owners of lifted trucks, rock crawlers, and expedition vehicles who prioritize suspension responsiveness and adjustability over longer travel distances. The four-stage compression and fifteen-stage rebound settings enable users to dial in behavior for both smooth highway driving and aggressive terrain without swapping components. Each shock is sold individually, requiring purchase of four units for complete suspension system replacement.

BILSTEIN's SZ series shocks are recognized in the aftermarket suspension industry for monotube reliability and field-proven durability in high-performance off-road platforms. The combination of adjustable damping and corrosion-resistant construction makes this shock a core component for vehicle owners seeking precision and longevity.
