Shock SZ/SL 9in Comp 3 Reb 4

The Shock SZ/SL 9in Comp 3 Reb 4 from BILSTEIN is a premium monotube shock absorber engineered for vehicles requiring precision suspension control and consistent damping performance. Designed for tactical and high-performance applications, this shock excels in environments where reliability under variable load conditions is critical. Whether you're outfitting a duty vehicle, off-road platform, or performance build, this monotube design delivers the consistent response needed when equipment weight and deployment scenarios demand predictable suspension behavior.

Built with BILSTEIN's proven monotube architecture, the Shock SZ/SL 9in Comp 3 Reb 4 features a digressive valve configuration that provides three stages of compression damping and four stages of rebound control. This multi-stage valve technology adapts damping force across the suspension stroke, offering firm initial response to bump inputs while maintaining compliance during larger compressions. The steel body with zinc plating resists corrosion in harsh field conditions, while the 1.81-inch outer diameter ensures compatibility with standard mounting hardware. Compressed length reaches 14.88 inches with full extension to 23.52 inches, providing balanced travel for both load-carrying capacity and articulation.

This shock assembly is ideal for vehicle operators, fleet managers, and suspension specialists seeking factory-quality replacements or performance upgrades for commercial and tactical platforms. The digressive valve design makes it particularly effective on vehicles operating under variable payload conditions—trucks, SUVs, and service vehicles benefit from the progressive damping curve that prevents bottoming while resisting fade during extended use. Installation is straightforward for technicians familiar with suspension work; confirm mounting eye configuration and vehicle-specific bushing requirements before ordering to ensure correct fitment.
