Shock Front GM Metric 4 Comp / 8 Reb

The BILSTEIN Shock Front GM Metric 4 Compensator / 8 Rebound monotube shock absorber is engineered for front-end suspension control on GM A-Body, F-Body, and G-Body platforms. This single shock unit delivers the precise damping characteristics required for responsive handling and consistent ride quality across a range of driving conditions, from street use to spirited driving scenarios.

The monotube design with C4-R8 valve technology provides tuned compression and rebound rates—4 clicks of compression adjustment and 8 clicks of rebound adjustment—allowing fine-tuning of suspension behavior without requiring complete replacement. The steel construction with black paint finish resists corrosion and integrates seamlessly with OEM or performance suspension setups. At 3.18 lbs and measuring 22.15 inches in length, this shock fits the dimensional envelope required for proper suspension geometry and clearance on metric-thread applications across these GM platforms.

This shock is ideal for owners of classic and muscle GM vehicles seeking direct replacement or performance upgrade capability. The adjustable valve stack allows users to optimize damping for load conditions, whether maintaining stock comfort or pushing toward firmer response for improved cornering stability. Each unit sold individually—verify pairing requirements for complete suspension systems and compatibility with existing control arm and mounting hardware on your specific model year and body configuration.

BILSTEIN is recognized for precision shock engineering and durability in both OEM supply and the aftermarket performance segment. The monotube architecture and valve-adjustable design reflect the brand's commitment to tunable suspension solutions rather than fixed-performance alternatives, making this shock suitable for builders who prioritize damping control and long-term reliability across varied driving scenarios.
