Bilstein 5100 Series 77-86 Chevrolet K30 / K30 Pickup Rear 46mm Monotube Shock Absorber

Bilstein is well-known for making solid suspension components, and their 5100 Series shocks are a popular choice for many trucks. This particular shock absorber is designed for the rear of a range of Chevrolet and GMC heavy-duty pickups, including models like the 1977-1986 Chevrolet K30 and the 1969-1974 GMC K35/K3500 Pickup. It's built to handle custom suspension setups and offers a significant upgrade over stock, especially if you're looking for more consistent damping.

What makes this shock stand out is its 46mm monotube design. This construction helps keep the damping fluid cool and prevents the shock from losing effectiveness, or 'fading,' even under tough conditions or heavy use. It also features Bilstein's patented digressive valving, which means it can instantly adjust to changes in the road or trail surface, giving you improved control. The body is zinc-plated steel for durability, and it comes with standard 5/8 inch bushings for mounting.
