Product Description

The Bilstein 33-230351 is a universal B8 5125 Series monotube shock absorber engineered for custom suspension applications where vehicle-specific parts are unavailable. Its high-gas pressure monotube design and self-adjusting deflective disc valving provide consistent, responsive damping performance across a wide array of conditions, making it a reliable upgrade for lifted trucks, bespoke suspension builds, and aftermarket projects.

Finished with a corrosion-resistant zinc-plated smooth body and supplied with a black protective bellows boot, this shock is built to withstand rugged use and variable terrain. The stem-to-eye mounting configuration and approx. 10.28" of travel offer flexibility in custom setups, though vehicle-specific adapters or mount hardware may be required for exact fitment. Sold individually, the 33-230351 shock is ideal for suspension builders and automotive enthusiasts crafting lifted or modified suspension systems.
