Shock SZ/SL 7in Comp 4 Reb 4

The Shock SZ/SL 7in Comp 4 Reb 4 by BILSTEIN is a professional-grade monotube shock absorber engineered for demanding off-road and performance driving applications. This 7-inch compensator shock delivers precision damping control through its advanced digressive valve design, making it the ideal choice for truck owners, off-road enthusiasts, and suspension tuners seeking responsive handling and superior ride quality in challenging terrain and varied driving conditions.

Built with BILSTEIN's proven monotube construction, the Shock SZ/SL 7in Comp 4 Reb 4 features a robust steel body with zinc plating for corrosion resistance and extended service life. The digressive C4-R4 valve configuration adapts damping force across the shock's travel range, providing firm initial response that softens under sustained compression—essential for maintaining traction during wheel articulation while preventing harshness over bumps. At 1.81 inches OD with 13.15-inch compressed and 20.08-inch extended lengths, this shock integrates seamlessly into properly-designed suspension systems while delivering controlled energy absorption and rebound characteristics that enhance both comfort and control.

Installation as a single unit (each) requires mounting compatibility with your vehicle's existing suspension geometry and spring rates. This shock performs exceptionally well in lifted suspension setups, trail-rated platforms, and performance applications where factory damping falls short. Proper installation by a qualified suspension technician ensures correct preload, valving response, and longevity. The 3.8-pound weight and compact footprint make handling and fitment straightforward for experienced installers working on light trucks, SUVs, and performance vehicles demanding reliability under extreme conditions.
