The ReadyLift 2" lift kit for the Silverado Trail Boss and Sierra GMC AT4 1500 features DOM tube steel upper control arms that have TCT pivot bushings that are maintenance free and 1-ton ball joints. This design is to improve alignment retention after installing the lift kit. The upper and lower strut spacers are made using CNC machined, aircraft-grade billet aluminum. The rear is lifted using a set of 3" tall OE style cast iron rear lift blocks along with u-bolts. These GM models come from the factory with a 2" front lift that includes a longer front strut assembly. Because of this design, a traditional leveling kit presents binding problems with the factory control arm ball joint and contact with the lower strut/CV axle assembly. The front fender opening design is different on the AT4 and Trail Boss models. Due to this difference each model has different tire size recommendations.
