Weak OEM ball joints and upper control arms present lots of problems by limiting suspension travel on lifted trucks. The more you lift, the more likely you are to begin having issues. These CST High Angle Ball Joints feature OEM Style non greaseable bushings that give you all the strength and function of a uni ball, but with the longevity of a ball joint. The CST Ball joint is designed to hold up in extreme weather conditions and features a stylish billet cover plate and boot. This should result in no maintenance and a set of upper control arms that lasts as long as you own the vehicle.
The part number for this item is CSS-C2-21 and this PAIR of upper control arms fits 2011-2019 Chevy Silverado and GMC Sierra (2500HD, 3500 only) models.
