About this kit

4-Inch Lift Kit with N3 Shocks, fitment-checked

Rough Country 355.20 is a 4-inch lift kit for the 1978-1993 Dodge Ramcharger 4WD and the 1978-1981 Plymouth Trailduster 4WD. It is a leaf-spring kit front and rear, packaged with two N3 shock pairs. It fits only trucks running the Dana 44 front axle, and it does not fit models with the Cummins diesel engine.

This 4-inch lift kit for the 1978-1993 Dodge Ramcharger 4WD and 1978-1981 Plymouth Trailduster 4WD replaces the springs at both ends rather than stacking on top of the factory setup: front and rear lifted leaf springs, a Dana 44 three-bolt steering block, U-bolts, a spring bushing and sleeve kit, an installation kit, and two N3 shock pairs. The new rear springs take the place of the factory block. Confirm you have the Dana 44 front axle and no Cummins diesel before ordering. Rough Country lists installation at 6 - 8 hours. Shipping weight: 266.0 lb.
