4-Inch Lift Kit with N3 Shocks, fitment-checked
Rough Country 350.20 is a 4-inch lift kit for 1975-1977 Dodge Ramcharger and Plymouth Trailduster 4WD models. It uses replacement front and rear leaf springs plus N3 shock pairs, and fits only trucks with the Dana 44 front axle. Models with the Cummins diesel engine are excluded.
This 4-inch lift kit for the 1975-1977 Dodge Ramcharger and Plymouth Trailduster 4WD builds height with replacement front and rear leaf springs instead of blocks, so the factory rear block comes out during the install. The front side adds a 3 bolt Dana 44 steering block to keep steering geometry in line, and N3 shock pairs cover both ends. U-bolts, a spring bushing and sleeve kit, and an installation hardware kit fill out the rest of the box. Budget 6 - 8 hours of wrench time. Confirm you have the Dana 44 front axle before ordering. Shipping weight: 265 lb.
