Enhance your Trail Boss or AT4 with improved ride height and performance.
Fabtech's Upper Control Arm lift kit offers a 1-1/2 Inch increase in ride height for Trail Boss and AT4 models, effectively enhancing ground clearance without causing suspension bind at full droop. This kit allows vehicles with a factory 2 Inch lift to achieve a stance comparable to a standard model equipped with a 3-1/2 Inch lift kit, accommodating up to 33 Inch tall tires. The inclusion of tubular Upper Control Arms with heavy-duty ball joints ensures proper alignment and geometry adjustments necessary for the new ride height.
The design of this lift kit eliminates the need for differential drop brackets, allowing CV axles to function correctly under the new GM suspension geometry introduced in 2019. The Performance rear shocks, featuring a twin tube design, provide a balanced highway ride while maintaining the capability to handle off-road conditions effectively. This kit is designed for easy installation, making it accessible for those looking to enhance their vehicle's performance without extensive modifications.
