Peak Billet Upper Control Arms - 19+ GM 1500 / 22+ ZR2/AT4X

Introducing our new Billet Upper Control arms for the 2019+ Silverado/Sierra 1500/ZR2/AT4X. These new arms are machined from solid billet aluminum to the highest standards possible.

There are multiple issues when lifting your vehicle with stock upper control arms. Both the geometry and strength are compromised due to over articulating the stock arms. We solved these problems by designing our upper control arms with increased castor and repositioned pivot angles reducing stress on the joints. The increased castor allows for proper alignment and improved handling.

We also replaced the weak factory ball joints with 1.25” stainless steel Teflon coated ProBearing uniballs for maximum strength and increased articulation. We provide a machined dust cap for longer life and lower maintenance.

For the inner pivots we used heavy duty Teflon coated ProBearing ¾” Heims for additional camber and caster adjustability. Another awesome feature is our adjustment barrels to allow you make adjustments on the vehicle without having to take the arms out of the truck

To mount the arms to the spindle we include high grade 17-4 stainless steel misalignment spacers and military grade hardware. All of the components on our upper control arms are rebuild-able or replaceable to make this product last a lifetime. The arms come preassembled and include detailed instructions for easy installation.
