Product Description

The Bilstein 33-225616 is a rugged universal coilover shock absorber from Bilstein’s B8 8125 Series, engineered for custom suspension builds, high-performance off-road use, and aftermarket applications where direct vehicle-specific shocks aren’t available. Featuring a robust 60 mm monotube body with a zinc-plated threaded design, this coilover allows for easy ride height adjustments and dual-rate spring compatibility, making it ideal for suspension builders and enthusiasts who want to fine-tune ride quality and performance.

Equipped with a remote reservoir and high-temperature hose, the 33-225616 offers improved heat dissipation and fade-free damping in demanding conditions. A competition-designed 3-stage seal pack and a 22 mm case-hardened piston rod provide durability and strength for rugged terrain. The owner-rebuildable design allows long-term serviceability, and the threaded body accommodates industry-standard 3.0″ ID coil springs for flexible setup options. Because this part is universal, proper installation requires matching the shock’s dimensions and mounts to your specific suspension geometry or using appropriate adapters and hardware.
