KSP PERFORMANCE engineered these tubular, adjustable front upper control arms to restore proper suspension geometry for 2–4 inch lifts, using thicker cold-drawn tubing, greaseable sockets, and heavy-duty ball joints. The powder-coated finish and CNC-machined components aim to deliver corrosion resistance and consistent fit on a wide range of GM platforms.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these control arms improve handling after a lift?\u003c\/h3\u003e\n\u003cp\u003eBy replacing the factory upper arms with adjustable tubular A-arms, the suspension’s caster and camber can be returned closer to OEM angles, which stabilizes steering and reduces premature tire wear.
