The Bilstein B6 4600 rear shock is a 46mm monotube gas-pressure damper built for the 1982 Dodge D50 Custom 4WD. The manufacturer describes the B6 as a bolt-on upgrade for stock suspension, tuned firmer than OE, that sharpens control on your existing springs at original ride height. For a D50 owner who doesn't want to lift or lower the truck, that means better damping control on rough trails and loaded hauling without changing the suspension geometry. The manufacturer also points to a 63% larger working piston for sharper damping, and says each unit is made in Germany and endurance-, salt-spray-, and scratch-tested before shipping.
Choose this over a stock replacement when you want the same mounting and ride height with firmer, more consistent damping. Because the B6 is built to OE dimensions, it bolts in where the original shock sat. You can also replace only the rear pair if you're upgrading in stages. Fitment listings for this part vary by year, trim, and drive type, so confirm the 1982 D50 Custom 4WD application with the manufacturer by VIN before ordering.

The manufacturer describes the B6 as a bolt-in replacement that requires no modifications, installing like the original shock at stock height. Because it can be fitted to the rear axle alone, this is a straightforward single-axle job rather than a full suspension rebuild. Check the manufacturer's installation instructions for torque specifications and mounting order before you start, and keep the factory springs in place as the manufacturer's design intends.
