Fits: 2020 thru 2023 Chevy Silverado/GMC Sierra 2500HD/3500HD L5P Duramax Diesel 

ReadyLift UCAs are laser cut and CNC-bent from .125 4130 chromoly plate steel creating an incredibly strong package engineered to be used on new 2020-23 GM HD trucks. The critical pivot points are maintenance-free and extremely durable for long-lasting use. One-ton spring loaded 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, 44-3035 control arms include CNC machined billet aluminum caps which helps extend the life of the ball joints. Frame side pivots feature 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 Heavy-Duty Upper Control Arm features a rugged Anthracite Gray powder coat finish along with a stainless steel ReadyLIFT brand arm badge.
