Product Description

The Bilstein 33-104652 is a high-performance **B8 5125 Series rear shock absorber** engineered for lifted classic Chevrolet and GMC C/K heavy-duty pickups from **1969 through 1986**. Its high-pressure monotube design with a 46 mm piston and self-adjusting deflective disc valving delivers consistent, fade-free damping performance, ideal for pickup trucks modified with rear lift kits. The zinc-plated finish and protective boot help resist corrosion and extend durability in rugged driving conditions.

Designed to replace and improve upon stock shocks on lifted suspensions, this shock enhances ride comfort, vehicle control, and handling - whether driving on pavement or uneven terrain. The eye-to-eye mounts with standard 5/8" bushings make installation straightforward. Sold individually, it's recommended to use two shocks per axle for balanced performance. The 33-104652 is a strong choice for classic Chevy and GMC truck enthusiasts building lifted or custom suspension systems.
