Fabtech 19-20 GM K1500 P/U w/Trail Boss/At4 Pkg Diesel 4in Perf Sys w/Dl 2.5 & 2.25

If you're looking to give your 2019-2020 GM K1500 pickup, specifically a Trail Boss or AT4 model with the diesel engine, a significant lift for tackling tougher terrain and fitting larger tires, this Fabtech 4-inch Performance System is designed for that job. It builds upon the factory 2-inch lift these trucks already have, adding another 4 inches for a total of 6 inches of lift, which is enough to clear 35-inch tall tires comfortably. This system is engineered to work with the truck's existing suspension, maintaining a near stock track width so your tires stay tucked under the fenders for a clean look.

Fabtech has put a lot of thought into the geometry of this system. The heavy-duty 1/4-inch thick steel crossmembers are arched to maximize ground clearance and feature a welded box design for added strength. They also use the factory alignment cam pins, making adjustments straightforward. The extended length ductile iron steering knuckles are designed to eliminate bump steer throughout the suspension travel, giving you a more controlled and comfortable driving experience, especially at higher speeds. Up front, the system replaces the stock coilovers with Fabtech's Dirt Logic 2.5 Coilovers. These are built for aggressive off-road use but are tuned to provide a surprisingly supple ride on the road. In the rear, Dirt Logic 2.25 shocks work with a new 5-inch block and U-bolt system (replacing the factory 2-inch block) to balance the ride and ensure full suspension travel without over-cycling the components.

This kit comes with a 5-year, 60,000-mile powertrain warranty from Fabtech, offering peace of mind with your investment. It's a comprehensive system designed to give your Trail Boss or AT4 a substantial lift while maintaining excellent on- and off-road manners and steering control.
