Built from forged T6 aluminum and finished with precision machining, the set includes greasable, zinc-nickel coated ball joints and polyurethane bushings to improve durability, steering feel, and suspension geometry for lifted applications. They are engineered to fit most 2–4\" lift setups while offering increased articulation and reduced maintenance compared with OEM parts.\u003c\/p\u003e\n\n\u003ch3\u003eWill these control arms fit my lifted Silverado or Sierra?\u003c\/h3\u003e\n\u003cp\u003eThey are intended for 2007–2018 Silverado and Sierra 1500 models when the truck has roughly 2–4\" of lift.
