Fits: 2020 thru 2024 Chevy Silverado/GMC Sierra 1500 LM2/LZ0 Duramax Diesel

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. Peak solved these problems by designing their arms with increased castor and repositioned the pivot angles reducing stress on the joints. The increased castor allows for proper alignment and improved handling. They also replaced the weak factory ball joints with 1” stainless steel uniballs for maximum strength and increased articulation. For the inner pivots they used machined delrin bushings with grease fittings for easy servicing. 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.

• Chromoly Upper Control Arms

• Grease Fittings

• Zinc Plated Bushing Washers
