Bilstein B8 5125 Shock Absorber, 17.11 Collapsed, Eye/Stem, Zinc Plated

The Bilstein B8 5125 is built for custom suspension builders who need a high-quality monotube shock without being locked into a direct-fit catalog option. This is the unit we recommend when you're running a non-standard setup and need a shock you can size and tune to your specific build.

The 46mm monotube design runs high gas pressure and uses self-adjusting deflective disc valving — that's what gives this shock its responsive feel across changing surface conditions. With a 17.11" collapsed length, 28.36" extended length, and 11.25" of stroke travel, this specific configuration covers a meaningful range of custom lift and geometry scenarios. The stem-to-eye mount configuration, 5/8" hour glass bushings, and 14mm shaft are all industry-standard dimensions that make integration straightforward for experienced builders.

Compression is rated at 755 and rebound at 3,775 (both at 52 m/s). The smooth body, non-coilover design keeps it clean for builds where a coilover isn't the right call. Zinc plated finish and a black bellows boot are included. A limited 90-day warranty is included from Bilstein.

We stock this as part of our custom suspension builder inventory — it's a serious component for serious builds, not a plug-and-play replacement.
