About this part
Lift Kit, fitment-checked
Aimed squarely at the factory off-road trims — LT Trail Boss and AT4 — rather than the standard trucks. One hard condition: it will not work with rear mono-leaf springs.
Most of ReadyLift's GM half-ton kits exclude the Trail Boss and AT4. This one is built for them, and the fitment carries no other trim. Application is the Chevrolet Silverado 1500 LT Trail Boss and the GMC Sierra 1500 AT4, both 2019 to 2023. The single condition on the part is the rear spring: trucks with rear mono-leaf springs are not compatible, which is worth checking under the truck rather than assuming from the build sheet. ReadyLift lists more than one part number against this application, so confirm the configuration before ordering.
