Bilstein 33-321929 SZ Series Motorsports Shock Absorber - 46mm

The Bilstein SZ Series shock absorber is a purpose-built motorsports suspension component designed for racing applications where sanctioning body rules prohibit or don't require rebuildable shock construction. Engineered with a robust 46mm monotube piston design, this shock delivers consistent damping performance under the extreme demands of competitive racing.

Key Features:

• 46mm monotube piston design for enhanced heat dissipation and consistent performance
• Durable steel body construction with smooth finish for reliable operation
• Standard digressive valve settings utilizing proprietary spring steel valve discs
• Tuned damping curves optimized for motorsports applications
• Coilover conversion capability with separately available conversion kit
• Non-rebuildable sealed design compliant with many racing class regulations

Bilstein's SZ Series shocks are available in multiple lengths and valve configurations to suit a wide range of racing chassis and suspension geometries. The digressive valve design provides firm initial damping control that transitions to a softer rate as shaft velocity increases, delivering excellent body control while maintaining tire contact over rough surfaces. Ideal for club racers, autocross competitors, and sanctioned racing series with specific shock absorber requirements.
