Peak Suspension UCA Chevy Silverado 1500 LTZ & ZR2

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 factory arms. We solved these problems by designing our arms with increased castor and repositioned the 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” stainless steel uniballs for maximum strength and increased articulation. Our upper control arm is designed to last, with superior handling and increased articulation that'll make your truck stand out, no matter where you go.

Our UCA's feature machined delrin bushings with lube fittings, ensuring a smooth, long-lasting ride. Every part of these arms can either be rebuilt or replaced, meaning you can enjoy them for a lifetime. Pre-assembled, Peak UCA's come with comprehensive instructions for a straightforward installation.
