Bilstein 8125 Series 23in Extended Length 15in Collapsed Length 46mm Monotube Shock Absorber

Bilstein is well-known for making solid suspension components, and their B8 8125 series coilovers are a prime example of that expertise. This particular shock absorber, part number 33-225500, is built for custom coilover setups where serious off-road performance is the goal. It's a 46mm monotube shock designed to handle a lot of abuse and provide consistent damping, even when things get rough.

What sets this shock apart is its remote reservoir. This external tank holds extra oil, which helps keep the shock cool under intense use, preventing fade and maintaining consistent performance. The threaded body is a practical touch, allowing for easy ride height adjustments and spring changes, which is crucial when you're dialing in a custom suspension. Inside, you'll find a competition-designed, 3-stage seal pack to keep dirt and debris out, and a 22mm hard-chromed piston rod that's incredibly strong and resistant to damage from rocks and sand. All these components are machined to precise tolerances right here in the USA.

This shock absorber is also owner rebuildable, meaning you can get replacement parts from Bilstein if needed down the road. It's a well-built piece of equipment designed for demanding off-road conditions and custom suspension builds.
