Rough Country


6-inch Suspension Lift Kit

The power of N2 comes to 2WD with Rough Country's 6-inch N2 Suspension Lift for 2WD GM 1500 models. This all-inclusive lift kit features heavy duty components; powdercoated in hammered black for an aggressive appearance and providing enough height to run up to 35-inch tires. A set of Fabricated Rear Anti-Wrap Blocks are engineered to give plenty of lift while their unique trapezoid shape and wider surface area makes them significantly less susceptible to axle wrap.

This kit also features our custom-valved nitrogen charged N2.0 shocks, with 10-stage velocity sensitive valving that allows for a smooth highway ride and outstanding off-road control - all from the same shock. Bring the power of N2 to your truck and get the most out of your 2WD.
