Product Details

The Bilstein B8 5125 shock absorber is engineered for custom suspension applications where direct-fit options aren't available. This high-pressure gas monotube shock delivers exceptional performance and durability for builders creating unique suspension setups on trucks, off-road vehicles, and specialty applications.

Key Features:

  • 46mm monotube design with high gas pressure for superior damping control and fade resistance
  • Self-adjusting deflective disc valving automatically adapts to changing road conditions
  • Available in multiple lengths and valve rates to accommodate diverse custom applications
  • Industry-standard 5/8" hourglass bushings for universal compatibility
  • Eye/eye and stem/eye mount configurations available for maximum mounting flexibility
  • Zinc-plated steel body with black enamel finish for corrosion resistance

Bilstein's monotube technology places the piston and oil in a single pressure tube, separating them from the high-pressure nitrogen gas with a floating dividing piston. This design provides consistent performance across all temperature ranges and prevents aeration under demanding conditions. The B8 5125 series is the go-to choice for professional suspension builders, fabricators, and enthusiasts who demand precise control over their custom suspension geometry.

This shock absorber is sold individually and requires selection of appropriate length and valving for your specific application. Bilstein's reputation for quality and performance makes the B8 5125 series a trusted solution for everything from custom truck builds to race vehicles.
