Designed for Trail Boss and AT4 owners who want additional ride height to accommodate full-size 33" tires, this Fabtech Upper Control Arm lift kit raises the ride height without compromising suspension travel or causing coil bind. The kit adds front lift while preserving proper coilover geometry and includes components to improve front suspension alignment at the new ride height.
Front lift is achieved with an aluminum spacer at the top of the coilover and a small preload spacer under the coil of the factory coilover shock. Tubular upper control arms with heavy-duty ball joints correct suspension geometry for the increased ride height. Rear lift is provided with 1" blocks and u-bolts; some owners may choose to omit the rear blocks to achieve a leveled stance. Performance rear shocks use a twin-tube design to balance highway comfort and off-road capability.
*Compatibility and installation notes: This kit is intended for 2019–24 Chevy Silverado 1500 Trail Boss and GMC Sierra 1500 AT4 4WD models; it assumes the factory two-inch lift on those models. It does not fit standard cab configurations. It is not compatible with vehicles equipped with adaptive ride control, composite rear leaf springs, or Super Cruise functionality. This kit may require non-OEM wheel and tire setups to achieve the intended fitment and clearance.
