Product Description

The Bilstein 33-230405 is a universal B8 5125 Series monotube shock absorber engineered for custom, lifted, and aftermarket suspension applications where direct vehicle-specific parts aren't available. Its high-gas pressure monotube construction with velocity-sensitive valving delivers consistent and reliable damping performance across a range of conditions - providing improved control compared to many standard shocks. The unit's zinc-plated smooth body enhances corrosion resistance for demanding environments.

Featuring an eye-to-eye mount configuration with standard 5/8" bushings and approximately 12.25" of travel, this shock offers flexibility for a variety of custom suspension geometries. The included protective black bellows boot helps guard the shaft from road or trail debris. Proper fitment requires matching the shock's dimensions and mount type to your specific setup or using suitable adapters. This makes the 33-230405 a strong choice for suspension builders and enthusiasts upgrading damping performance in lifted or custom vehicle builds.
