2019-21 4WD Chevy Silverado Trail Boss, GMC Sierra AT4 1500 1.5" UCA lift kit, Performance shocks

The new GM Silverado Trail Boss and Sierra AT4 models come with a factory 2" lift. By installing the Fabtech 1.5" lift kit, the result will be the same as non-Trail Boss and non-AT4 models that have a 3.5" lift kit. This allows for 33" tires. Heavy duty ball joints are featured in the tubular upper control arms to address front suspension geometry with the additional 1.5" of ride height. This allows for proper alignment. An aluminum spacer is inserted at the top with a small preload spacer under the coilover shock. This design will position the coilover properly to avoid coil bind or over extending travel that could otherwise lead to future damage. Differential drop brackets are not required with this new GM suspension design. A 1" rear block kit is included, however, some owners may choose not to install this. Hydro rear shocks provide a great highway ride with good offroad damping.
