Fabtech 2011 GM C/K2500HD/3500HD 4in System - Replacement Component Box

If you're looking to lift your 2011-2019 Chevrolet Silverado 2500 HD or 3500 HD, or GMC Sierra 2500 HD or 3500 HD, this Fabtech 4-inch lift system replacement component box is designed to get the job done. This kit focuses on providing the core components needed to achieve the lift while maintaining factory steering geometry and allowing you to keep your stock tires and wheels. It’s a well-thought-out approach to lifting your heavy-duty truck without requiring major modifications like a driveshaft change or welding.

Inside this box, you'll find a set of left and right machined spindles, which are key to achieving the 4-inch lift. It also includes left and right upper control arms, designed to work with the new spindle height. A notable feature is the inclusion of high-travel ball joints, which help ensure a more comfortable ride and better articulation than you might expect from a lift kit. Fabtech has engineered these components to retain your factory steering centerlink and upper control arms, simplifying the installation process and ensuring a direct fit. This attention to detail means you get increased caster for improved steering control after the lift is installed.

The installation process is designed to be straightforward, with a quick, no-weld setup, making it accessible for many DIYers or a faster job for a professional shop. This kit is a replacement component box, so it's important to ensure you have the rest of the necessary components for a complete installation or that this box is intended to replace specific parts in an existing system. Fabtech has over 20 years of experience in suspension design, using advanced software and rigorous testing to develop reliable lift systems.
