About this kit
4-Inch Lift Kit with N3 Shocks, fitment-checked
Rough Country 331.20 is a 4-inch lift kit for 1970–1974 Dodge W100, W200, and W300 4WD models. The kit is built around front and rear lifted leaf springs, a Dana 60 steering block, U-bolts, spring bushings and sleeves, hardware, and two N3 shock pairs. It fits only trucks with the Dana 60 front axle and does not fit trucks with the Cummins diesel engine.
This 4-inch lift kit for the 1970–1974 Dodge W100, W200, and W300 4WD is a spring-swap lift rather than a spacer setup: replacement leaf springs go in front and rear, and the new rear springs take the place of the factory block. A four-bolt Dana 60 steering block, universal U-bolt kit, bushing and sleeve kit, installation hardware, and two N3 shock pairs round out the box. Rough Country lists 6 - 8 hours for the install, and a downloadable installation guide is available. Confirm your front axle and engine against the exclusions before ordering.
