Fabtech 19-20 GM C/K1500 P/U w/Trail Boss/At4 Pkg 4in Basic Sys w/Stealth

If you're looking to give your 2019 Chevrolet Trail Boss or GMC AT4 a more aggressive stance and the ability to clear larger tires, this Fabtech 4-inch Basic Suspension System is designed for you. These trucks already come with a factory 2-inch lift, and this system adds another 4 inches on top of that, giving you a total of 6 inches of lift over a standard 1500. This setup allows for the clearance needed to run 35-inch tall tires, transforming your truck's appearance and off-road capability.

Fabtech has engineered this system to maintain excellent drivability, both on and off the pavement. You'll notice zero bump steer, which significantly reduces driver fatigue on longer trips and improves overall control. The system is designed to keep the track width close to stock, ensuring your tires stay tucked neatly under the fenders for a clean look. The steering knuckles feature Fabtech's proprietary geometry, providing a generous lock-to-lock turning radius that's helpful for maneuvering in tight spaces. The heavy-duty 1/4-inch thick steel crossmembers are built to last and incorporate OE-style alignment cam pins, making adjustments straightforward using the factory cams. To prevent vibration at higher speeds, triple front differential mounts are included to properly reposition the differential. This kit retains your factory Trail Boss or AT4 coilover shocks, relocating them from the bottom to achieve the 4-inch lift while still allowing for full steering travel. In the rear, the factory 2-inch block is removed and replaced with a taller 5-inch block and U-bolt system to achieve the desired lift height.

This comprehensive system addresses all the critical aspects of the Trail Boss and AT4 suspension to ensure proper wheel travel and steering range without over-cycling the components. As an added benefit, this Fabtech lift system comes with a free 5-year, 60,000-mile powertrain warranty, giving you peace of mind with your investment.
