About this kit
4-Inch Lift Kit with N3 Shocks, fitment-checked
Rough Country 340.20 is a 4-inch lift kit for 1977–1993 Dodge W-Series 4WD trucks, built around front and rear lifted leaf springs plus two N3 shock pairs. It fits only trucks with the Dana 44 front axle and does not fit models with the Cummins diesel engine. The new rear springs take the place of the factory lift block.
This 4-inch lift kit for 1977–1993 Dodge W-Series 4WD covers W150 from 1977–1993, W200 from 1978–1980, and W250 and W350 from 1981–1993 as listed in the fitment section. The box carries front and rear lifted leaf springs, a Dana 44 steering block, a universal U-bolt kit, a spring bushing and sleeve kit, an installation kit, and two N3 shock pairs. Confirm your front axle and engine against the exclusions first, since the rear springs replace the factory block. Rough Country lists the job at 6 - 8 hours, and a downloadable installation guide is available.
