Bilstein 8125 Series 27in Extended Length 17in Collapsed Length 46mm Monotube Shock Absorber

If you're building a custom off-road suspension, you need components that can handle the abuse. This Bilstein B8 8125 series shock absorber is designed for those serious custom applications where extreme conditions are the norm. It features a 46mm monotube design, known for its consistent performance and ability to manage heat effectively, especially when paired with its remote reservoir.

The remote reservoir is key here; it holds extra fluid, which helps keep temperatures down during long, hard runs. This means you get fade-free damping even when the shocks are working overtime. The shock body itself is zinc-coated and threaded, allowing for easy ride height adjustments and spring swaps, which is a big help when fine-tuning your suspension. For durability, it sports a 22mm hard-chromed piston rod that resists damage from sand and rock chips, and a competition-designed, 3-stage seal pack to keep contaminants out in harsh environments. Everything is machined to tight tolerances and made in the USA.

This shock absorber is owner rebuildable, and replacement parts are available from Bilstein, so you can keep it running for a long time. It's a well-built piece designed for custom builds where reliability and performance are paramount.
