Fabtech 19-20 GM K1500 P/U w/Trail Boss/At4 Pkg 1.5in Budget Sys w/Stealth

The aluminum spacer at the top of your factory coilover and a small preload spacer under the coil are key to this 1.5-inch lift system from Fabtech. This setup is specifically for 2019-2020 GM K1500 trucks equipped with the Trail Boss or AT4 package. These trucks already have a factory 2-inch lift, and this kit adds another 1.5 inches, giving you a total of 3.5 inches of lift compared to a standard model. This increased height allows you to clear larger 33-inch tall tires, specifically 33x12.50R18 or 20-inch tires, without causing suspension bind at full droop or overextending travel.

Fabtech's design addresses the geometry changes that come with lifting your truck. The included tubular upper control arms feature heavy-duty ball joints, which are crucial for maintaining proper alignment with the new ride height. Unlike some other kits, this system doesn't require differential drop brackets for the CV axles on the new GM suspension geometry, simplifying installation. In the rear, 1-inch blocks and U-bolts are included to lift the back, though you can choose not to install the rear blocks if you prefer a level stance. The Stealth rear shocks are a standout feature, built with a monotube design and a Nitrocarb piston rod that resists corrosion and rock chipping, offering a balanced ride for both highway cruising and off-road damping.

This kit is designed for an easier installation and allows for the suspension to be restored to stock if needed. You'll gain increased ground clearance and fender clearance for those larger tires, all while maintaining a smooth, quiet ride thanks to the extended range upper ball joints. If you're looking to give your Trail Boss or AT4 a bit more capability and a more aggressive stance, this Fabtech system is a solid option.
