Bilstein B8 5125 Shock Absorber 17.01 Eye/Eye Zinc-Plated Monotube

The Bilstein B8 5125 is built for custom suspension builders who need a high-quality monotube shock where no direct Bilstein application exists. This is a raw, spec-to-spec tool: you select the length, valve rate, and mount configuration to match your build rather than relying on a catalog fitment.

This specific unit runs a 17.01-inch collapsed length and extends to 28 inches, giving you 10.99 inches of stroke travel. The 46mm monotube piston uses self-adjusting deflective disc valving with compression measured at 595 and rebound at 1810 (both at 52 m/s) — real numbers that tell a custom builder exactly what they're working with. Mount configuration is eye/eye with 5/8-inch hourglass bushings on both ends, and the smooth body zinc-plated finish resists corrosion without a reservoir adding bulk. A black bellows boot is included.

We recommend this shock to builders running lifted applications or non-standard suspension geometries where off-the-shelf shocks won't cut it. The high gas pressure monotube design delivers consistent, fade-free damping under load — no foaming, no fade. The 14mm shaft diameter adds durability where flex cycles are high.

Note the 90-day limited warranty. This is a purpose-built component, not a plug-and-play replacement — verify your collapsed and extended length requirements before ordering.
