Lift Kit for Trail Boss & AT4 (2019-2023)

About this part

Lift Kit, fitment-checked

A second part number covering the same off-road trims — Silverado LT Trail Boss and Sierra AT4, 2019-2023 — so confirm which configuration you need before ordering.

Read the rear suspension before anything else. the part rules out trucks with rear mono-leaf springs, and that is the only compatibility condition attached to it. Everything else about the application is straightforward: the Chevrolet Silverado 1500 in LT Trail Boss and the GMC Sierra 1500 in AT4, 2019 through 2023, with no drivetrain or cab qualifier. Because ReadyLift catalogs more than one part number against exactly this pair of trucks, the part number itself is the decision, and the data here does not describe what separates them.
