KSP Aluminum Forged Upper Control Arms for 2-4 inch lift Chevy Silverado/GMC Sierra 1500 2007-2018

KSP Performance Aluminum Forged Upper Control Arms are designed for 2 - 4 inch lift GM trucks, including Chevy Silverado 1500, GMC Sierra 1500 and Cadillac Escalade, from year 2007 to 2018.

Control arms are forged from premium 6082-T6 aluminum, offering strength that not just exceeds plastics and stamped steels, but also outperforms the commonly used aircraft-grade 6061 aluminum alloy for control arms.

Unlike steel, aluminum never rusts. Aluminum naturally forms a protective oxide layer that prevents this risk - no coating needed. That means it can stay reliable and safe, even in harsh and demanding off-road conditions. Plus, without paint or coating, aluminum control arms can showcase their raw metallic finish - shiny, sleek, and undeniably cool.

Thanks to aluminum's lightweight nature, our control arms can be built with a solid design. This dramatically boosts strength while still weighing less than hollow steel arms. The result: lighter, stronger, and more reliable off-road performance. Forging delivers exceptional durability, while the absence of weld seams eliminates weak points, reducing the risk of cracks or failure. CNC technology ensures every mounting point is cut with exceptional accuracy, delivering an excellent fit and enhanced performance.

KSP control arms are proudly designed and CAD engineered by our own team, ensuring excellent vehicle fitment while maximizing strength and overall performance. The fusion of bold geometry and flowing curves defines KSP signature design.

Ball joints and bushings are parts subject to wear. We have extended their service life, especially under off-road conditions, through improved design and provide a one-year warranty.

KSP ball joints and control arms are engineered together - optimized from the ground up for lifted vehicles and the demands of off-road. A spring-clip ball joint locks firmly in place after installation - yet with the right tools, replacement is quicker and easier than ever. Oversize ball means greater contact area, added strength, and wider adjustability - offering more range than OE ball joints to fit lifts from 2 to 4 inches with ease. A bellows design in the dust boot keeps it flexible under extreme angles - resisting tears and staying durable through years of hard use. Heat-treated, zinc-nickel coated bolts resist corrosion far beyond standard ball joints, extending life even in the harshest off-road conditions. And with an internal hex design, tightening bolts is smooth and secure - without unwanted rotation.

Polyurethane bushings are built tougher than rubber engineered to handle the demands of off-road and lifted trucks, while lasting far longer. We also optimized PU bushings, using a U-Groove design that makes them quieter than standard PU bushings. The split tube-and-bushing setup allows for easy manual installation without the need for a press
