The Bilstein 33-321950 SZ Series shock absorber is engineered specifically for motorsports applications where performance and durability are paramount. This race-ready shock features a robust 46mm piston design housed in a durable steel body with a smooth finish for consistent operation under demanding track conditions.

Key Features:

• 46mm monotube piston design for superior heat dissipation and consistent damping performance
• Steel construction with smooth body finish for durability in racing environments
• Standard digressive valve settings utilizing proprietary spring steel valve discs for responsive compression control
• Compatible with coilover conversion kits (sold separately) for adjustable ride height applications
• Non-rebuildable design ideal for racing series with sealed shock absorber requirements
• Available in various lengths to accommodate different suspension geometries

The SZ Series is specifically designed for racers competing in sanctioning bodies that either prohibit or do not require rebuildable shock absorbers. The digressive valving provides firm initial resistance that tapers off as shaft speed increases, delivering excellent body control during cornering while maintaining compliance over rough track surfaces.
