Description
Designed for the Rough Stuff. Height is important, whether for on-road visibility or off-road ability. This SuperLift 6-Inch Knuckle Suspension Lift Kit with Bilstein Shocks uses a “No Drop” torsion bar relocation bracket to keep the torsion bar assembly safe while off-roading and maximizing frame ground clearance. This Superlift Kit can expand your tire choices up to 37 inches while keeping perfect alignment specifications with CNC machined steering knuckles and heavy-duty lower control arm crossmembers
Rear Lift. The rear lift is achieved with a heavy-duty fabricated rear block. The primary axle U-bolts are captured in upper and lower plates with secondary U-bolts attached to the OE leaf spring. A fully functional, axle-mounted compression stop system prevents over-compression.
Installation. Installation time is estimated at 9 hours with mechanical expertise or a professional installation. No welding is required. This kit is compatible with factory Stabilitrac and anti-skid control features to prevent irritating dash lights.
Limited Lifetime Warranty. Superlift, LLC, is so confident in its line of suspension products that it carries a limited lifetime warranty on fabricated items and a 1-year warranty on all wearable items such as bushings, stabilizers, and shocks. Subject to the terms and conditions, please contact the manufacturer for full warranty details.
Application. This Superlift 6-Inch Knuckle Suspension Lift Kit fits all 2020-2025 Sierra 2500 HD Models without MagneRide.

Installation Time: Afternoon
Great Fit
I bought a previously lifted truck and the control arm bushings were bad. I didn't know where to get replacements. A buddy recommended American Trucks. I found replacement bushings easily on the American Trucks website. They were easy to install and fit perfectly.

Head turning
Extremely pumped to have this kit installed. Ride is extremely smooth and in my personal opinion pretty close to the stock ride. Took around 12 hours to complete. The kings really make it stand out from the rest.

Nice Lift!
Installation went well, about 8 hrs. Looks great. Truck rides stiff but it always did. I swapped out the 1.5 inch blocks for 2.5.

New life for the Ram
The Suspension lift kit gave much needed life to my ram. Old suspension was pretty tired after 170k miles and the handling, overall ride and looks that the kit offers for the price is unbeatable. highly recommend this kit to everyone.
