Shock SZ/SL 7in Comp 2 Reb 15

The BILSTEIN Shock SZ/SL 7-inch Compensator with 2 Rebound and 15 valve (MPN 33-321608) is a monotube shock absorber engineered for vehicles requiring precision damping control and consistent performance under demanding conditions. This unit delivers the responsiveness and valving sophistication BILSTEIN is known for in the OEM and motorsports market.

With a compressed length of 13.15 inches and extended length of 20.08 inches, this shock provides a stroke that accommodates moderate suspension travel while maintaining compact packaging. The 1.81-inch outside diameter fits standard shock mounts on compatible platforms. The C2-R15 valve configuration—combining compression damping with a 2-stage rebound circuit tuned for 15-valve response—ensures the shock absorbs impacts efficiently while maintaining controlled rebound without oscillation. Steel construction with zinc plating provides corrosion resistance, critical for durability in variable weather and salt-air environments. At 3.8 pounds, this single unit delivers substantial damping authority without excess weight penalty.

This shock is designed for vehicle owners and technicians seeking OEM-quality or rebuild-specification dampers for suspension systems where precise valving and repeatable performance matter. The SZ/SL series is common in European sport-luxury and performance platforms where tuned suspension geometry demands matched front and rear damping. Replacement or upgrade applications benefit from BILSTEIN's engineering heritage in both street and competition suspension.

Verify fitment by cross-referencing the part number 33-321608 with your vehicle's suspension specifications. Shocks are sold individually; matching pairs are required for proper suspension balance. Installation should be performed by qualified technicians familiar with suspension service and torque specifications.
