Product Details
If you're looking to give your 2011-2019 GMC Sierra 2500 HD or Chevrolet Silverado 2500 HD a more aggressive stance and improved ground clearance, this 4-inch basic lift system from Fabtech is a solid option. It's designed to work with both 2WD and 4WD models, giving you that lifted look and capability you're after.
Fabtech built this system with robust, heavy-duty construction in mind. The lower control arm crossmembers are made from 1/4-inch thick steel, giving them serious strength to handle off-road conditions. The ductile iron steering knuckles are a key component here; they're designed to keep your truck's track width close to stock. This means your tires will sit nicely under the fenders, maintaining a clean appearance, and it helps avoid issues with tire rub on the fenders or suspension components.
For the rear lift, the system uses a block and U-bolt configuration, a straightforward way to achieve the desired height. This kit includes Fabtech's DLSS shocks, which are tuned to work with the lifted suspension, offering a noticeable improvement in ride quality over stock for your lifted truck. When installing this kit, you'll want to refer to the manufacturer's instructions for the specific details on how everything bolts together, especially regarding the rear block setup.
