Product Overview
GMC Sierra K2500 K3500 4WD Complete Lift Kit
The RTZ GMC Sierra K2500 K3500 lift kit combines adjustable front forged torsion keys, rear lift shackles, and Doestch Tech DT8000 heavy-duty shocks for a matched suspension setup. It is listed for compatible Chevrolet and GMC K2500 and K3500 4WD pickups. The front lift is adjustable from 1 to 3 inches, and the product title and included-parts list specify 1.75-inch rear lift shackles.
Adjustable Front Lift with Forged Torsion Keys
This kit includes a pair of re-indexed forged torsion keys designed to provide 1–3 inches of adjustable front lift. The adjustment lets you choose a front height within that range to suit your intended stance. This is a 4WD application, so confirm your truck’s model, year, and drivetrain against the product fitment information before ordering.
1.75-Inch Rear Lift Shackles
The rear lift is provided by 1.75-inch adjustable shackles. The listing describes these shackles as robotically precision laser-cut, formed, and rolled. They are made in the USA and powder-coated to help resist rust. Paired with the front torsion keys, they form the front-and-rear lift setup described in the product title.
Doestch Tech DT8000 Heavy-Duty Shocks
A set of Doestch Tech DT8000 heavy-duty shocks is included. Listed features include twin-tube cellular gas construction, a 1.625-inch piston assembly with 30% more oil capacity, a larger Chromoly rod, external poly bump stops, aerospace-quality Teflon wiper seals, and double-welded ends. The product listing says the shocks are intended to improve control, stability, and drivability across changing terrain.
Kit Contents, Installation, and Fitment
The kit includes a pair of adjustable 1–3-inch forged torsion keys, 1.75-inch rear lift shackles, and a set of Doestch Tech DT8000 heavy-duty shocks. The listing describes installation as direct drop-in and bolt-on, with no cutting or welding required, and recommends an alignment afterward.
Inspect all parts before beginning installation. Suspension components are subject to extreme loads, so the seller recommends using a professional installer with suitable equipment and suspension-safety training.
