Optimize your Lincoln Navigator alignment and upgrade its front-end components with Supreme Suspensions® Upper Control Arm Kit. Rigorously tested by in-house ASE certified specialists, our control arms are meticulously CAD/CAM engineered, Laser Cut, CNC Bent and Professionally Welded from lightweight 4130 Chromoly Steel. Both stronger and harder than conventional steel, chromoly is an ideal material for the extreme demands of off-road environments. A proprietary 3-stage powder-coated finish protects against corrosion and keeps your control arms looking great for the life of your F150.
Each Upper Control Arm Kit features a pair of FK 1.25" PTFE-lined Uni-Ball Bearings in place of the factory upper ball joints. When compared to stock ball joints, Uni-Ball bearings offer superior strength and significantly improved articulation. The Teflon coating provides a super-smooth mating surface for seamless operation with minimal wear.
This tubular control arm kit is equipped with Zerk fittings to easily grease the included Heavy Duty Polyurethane Bushings, ensuring a long lifetime of durability and easy maintenance.
An alignment is always recommended if you are altering the height of your vehicle.
