• Never Rust：One-piece design forged aluminum control arm,lighter but stronger. Precision CNC machining is crucial to ensure the right dimensions.No welding spot and weak points,much lower ahance of anything breaking.Upgrading T6 aluminum also avoid rust even after melting snow. Each arm goes through magnetic particle inspection during production to make sure it's strong and perfect. Serviceable: Greasable socket can reduces corrosion and wear by allowing new lubricant to flush contaminant.The ball joint come with tower-shaped dust boots and exclusive KSP protective covers to prevent debris and make them last longer.Unlike uncoated iron ball joints prone to rust, KSP's heat treated ball joint pins are coated with a zinc-nickel alloy, which costs more but longer service life.Metal to metal ball joint outperforms common POM ball joints. Affordable：Corrects Ball Joint Angle for Lifted Applications.If you got a 2-4" lifted on your FORD truck,this aftermarket control arm is a good idea for upgrading or replacing worn out stock control arm.It has a greater range of motion than the original ball joint, which can correct the chassis perfectly . Can be well adapted to street and trail,especially for off-roading. Durable:The bushings are made of premium-quality polyurethane, which handles temperature extremes better than rubber. The groove design helps with lubrication, ultimately improving overall driving feedback and experience. Offering better handling performance and less noise.
