Bilstein 8125 Series 19in Extended Length 13in Collapsed Length 46mm Monotube Shock Absorber

Bilstein is well-known for making solid suspension components, and their B8 8125 series coilovers are built for demanding off-road use. This particular shock absorber, part number 33-225487, is a 46mm monotube design with an extended length of 19 inches and a collapsed length of 13 inches. It's intended for custom coilover setups where you need a specific amount of travel and the ability to fine-tune ride height.

What sets these apart for tough conditions is the incorporated remote reservoir. This reservoir holds extra fluid, which helps keep temperatures down and prevents fade, even when you're pushing hard off-road. The body is threaded, making it easy to adjust ride height and swap out dual-rate springs. Bilstein also includes a competition-designed, 3-stage seal pack to keep dirt and debris out, and the 22mm hard chromed piston rod offers excellent strength against impacts and abrasion.

These coilovers are designed to be rebuilt by the owner, and replacement parts are available from Bilstein. All components are machined to precise tolerances and made in the USA. If you're building a custom off-road suspension and need a robust, adjustable shock absorber, this Bilstein 8125 series unit is a strong option.
