Product Details

Bilstein’s B8 5100 line is built for lifted truck and SUV suspension setups that need a direct-fit shock absorber with application-specific tuning. This front shock uses a monotube layout to help maintain fade-resistant performance, while the digressive piston responds to road inputs with controlled damping. For buyers searching for a Bilstein shock absorber for a lifted Ford Ranger or Mazda B2300/B3000/B2500/B4000 front suspension, 24-187107 is the listed fitment-specific option.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Installation Notes

Verify the vehicle has the listed 6" a-arm and spindle style lift before ordering. Confirm mount style, collapsed length, and extended length against the existing shock and suspension travel.
