About this kit

3-Inch Lift Kit, fitment-checked

Rough Country 34370 is a 3-inch lift kit for compatible Dodge Ram 2500 (2003–2010), Ram 3500 (2003–2007), and Ram 2500 (2011–2013) 4WD trucks. Diesel applications only — gas-engine, dually, and Power Wagon trucks are not covered. The kit ships with coil springs and fabricated rear lift blocks.

This 3-inch lift kit for the 2003–2013 Dodge and Ram 2500/3500 4WD covers trims from ST and Tradesman up through Laramie Longhorn, including TRX and Outdoorsman applications listed in the fitment section. It is a bolt-on job that raises ride height and opens up ground clearance for larger tires. The rear lift blocks are fabricated rather than cast. Before ordering, confirm your truck is diesel-powered, single-rear-wheel, and not a Power Wagon. A downloadable Rough Country installation guide is available so you can walk the steps before the truck goes on jack stands.
