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

This Fabtech 4-inch Basic Suspension System is specifically designed for the 2019-2020 Chevrolet Trail Boss and GMC AT4 pickup trucks. 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 and the clearance needed to fit 35-inch tall tires comfortably. This setup allows your truck to sit at a similar height to a standard 1500 with a 6-inch lift and 35-inch tires.

Fabtech focused on creating a suspension that handles well both on and off the pavement. You'll notice a significant reduction in driver fatigue thanks to the elimination of bump steer throughout the suspension's travel, which also improves overall drivability. The system maintains a near-stock track width, keeping your tires tucked neatly under the fenders for a clean look. The proprietary steering knuckle geometry is engineered to provide an excellent lock-to-lock turning radius, making it easier to maneuver in tight spaces. The heavy-duty 1/4-inch thick steel crossmembers feature OE-style alignment cam pins that work with your truck's factory cams for straightforward adjustments. Triple front differential mounts are included to reposition the differential, ensuring vibration-free operation even at higher speeds.

This kit retains your factory Trail Boss and AT4 coilover shocks, relocating them from the bottom to allow for full steering range while achieving the 4-inch lift. In the rear, the lift is achieved by swapping out the factory 2-inch block for a new 5-inch block and u-bolt system. Fabtech has carefully considered all aspects of the Trail Boss and AT4 suspension to ensure proper wheel travel and full steering lock without over-cycling the components. As a bonus, this system comes with a free 5-year, 60,000-mile Powertrain Warranty for added peace of mind.
