67-30320 | ReadyLift Xtreme Duty Fabricated Upper Control Arms

2020-2025 GM Silverado/Sierra 2500/3500 HD 2WD/4WD Xtreme-Duty UCAs. Our Xtreme-Duty fabricated steel control arms found in our popular 3" SST Lift Kit are also available separately if you already have a leveling or lift kit! The new UCAs are Laser cut and CNC bent .125 4130 chromoly plate steel precision construction, creating an incredibly strong package engineered to be used on new 2020-25 GM HD trucks. The critical pivot points are maintenance-free and extremely durable for long-lasting use. Our 1-ton spring-loaded high-angle HD series ball joints maintain the factory driving experience and can take a beating from the excessive weight of heavy aftermarket wheels and tires. To protect the joint from nasty road debris such as salt and sand, our arms include CNC machined billet aluminum caps which helps extend the life of the ball joints. Frame side pivots feature our proprietary new TCT bushings which are self-lubricating and engineered to last. These new bushing include "side biter" washers to aid in maintaining alignment settings. The free-floating bushing design eliminates friction which is the most common culprit of traditional bushing failure. Each ReadyLIFT Extreme-Duty Upper Control Arm features a rugged Anthracite Gray powder coat finish along with stainless steel ReadyLIFT brand arm badge. These new arms are sure to start a new revolution in upper control arm expectations. Now is your chance to be the first to offer them to your customers who really do need a better UCA!
