What makes the monotube design better than a twin-tube shock?

The monotube design uses a single tube with a floating piston to separate oil and gas. This helps dissipate heat more effectively, preventing the shock from losing performance (fading) during heavy use or on rough terrain. It also allows for more precise valving adjustments.

Does this shock absorber come with mounting hardware?

This shock absorber comes equipped with industry standard 5/8 inch hour glass bushings for mounting. It is designed for custom applications, so you may need to verify compatibility with your specific suspension setup.

What is the purpose of the digressive valving?

The patented digressive valving allows the shock absorber to instantly react to changes in road or trail conditions. This means it can adjust its damping force very quickly, providing better control and a more stable ride whether you're on smooth pavement or uneven surfaces.

About this part

Product Details

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.
