Fits: 2011 thru 2019 Chevy Silverado/GMC Sierra 2500HD/3500HD LML/L5P Duramax Diesel

ReadyLIFT 44-3100 Heavy-Duty Upper Control Arms for 2011-2019 GM 2500/3500 HD trucks uses fabricated steel design technology. Laser cut and CNC bent .125 4130 chromoly plate steel precision construction creates an incredibly strong package engineered to be used on lifted trucks with 2"-8" of lift kits. 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, these arms include CNC machined billet aluminum caps which helps extend the life of the ball joints.

Frame side pivots feature new TCT bushings which are self-lubricating and engineered to last. These new bushings 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.
