7 Inch Lift Kit | NTD | M1 | w/ Overloads | Chevy/GMC 2500HD/3500HD (20-26)

Transform Your HD With Confidence: Upgrade your fourth or fifth-generation Chevy/GMC 2500HD/3500HD with Rough Country's 7-Inch Non-Torsion Drop Suspension Lift Kit. This high-clearance system adds serious attitude and off-road capability to your truck, delivering the height you need to run 37-inch tires, all while maintaining a clean, integrated factory look underneath thanks to its non-torsion drop design. Engineered for a Sleek, Factory-Fit Appearance: Unlike traditional kits that leave torsion bars hanging low and exposed, Rough Country's innovative non-torsion drop design keeps everything tucked up and streamlined. You'll enjoy unmatched ground clearance and a sharp, OEM-style appearance that complements the aggressive stance of your HD truck. Built for Strength and Precision: The kit includes rugged, laser-cut front and rear crossmembers crafted from durable steel for a precise, bolt-on fit. The signature "RC" logo adds a bold touch up front, while the heavy-duty differential skid plate offers extra protection during off-road adventures. Lifted knuckles, rear anti-wrap blocks, and a range of premium shock options, like Rough Country's nitrogen-charged N3s or the high-performance Vertex reservoir, ensure you get the ride feel and handling you demand. Ride Quality You Can Rely On: This lift system retains factory ride comfort and control, keeps axle geometry true to spec, and preserves OEM track width. No drivetrain modifications or differential drilling required, just a clean install and predictable performance, mile after mile. Backed by Rough Country's Limited Lifetime Replacement Guarantee: Drive with peace of mind knowing your lift kit is covered for the long haul.
