Product Details

The Bilstein B8 5125 shock absorber is engineered for custom suspension applications where direct-fit options are unavailable. This high-pressure gas monotube shock delivers superior damping performance and reliability for builders creating custom suspension setups on trucks, off-road vehicles, and specialty applications.

Key Features:

  • High-pressure gas monotube design for consistent performance and fade-free operation
  • 46mm piston with self-adjusting deflective disc valving technology adapts to changing road conditions
  • Industry-standard 5/8-inch hourglass bushings for universal compatibility
  • Available in eye/eye or stem/eye mount configurations to suit various mounting requirements
  • Sold individually by length and valve rate for precise custom fitment
  • Durable construction designed to withstand harsh off-road and heavy-duty use

The B8 5125 series gives suspension builders the flexibility to select the exact shock length and valving characteristics needed for their specific application. Whether you're building a custom lift kit, fabricating a one-off suspension system, or modifying a vehicle without aftermarket support, Bilstein's proven monotube technology ensures optimal handling and ride quality.
