New for 2020, our Camburg upper arms feature a billet aluminum cover for the uniball, protecting it from dirt and contaminants. The stock upper arms limit suspension performance when lifting your truck, but our arms address this issue. We replace the stock ball-joint with a larger 1.25 uni-ball bearing, increasing wheel travel and durability. The arms are made with thicker 1.50" x.188" wall tubing for strength and do not require removal of the factory droop stop/perch. Our arms are designed using CAD/CAM software and manufactured in-house with precision welding and CNC machining. They correct camber and caster, improve driving characteristics, and come with polyurethane frame pivot bushings and FK 1.25" PTFE-lined uniballs. The arms are powder-coated and include all necessary hardware. They are designed for 1-3" of lift and should not be used with longer shocks or lift kits without confirmation from our sales department.. Given the multitude of factors such as wheel size, offset/backspacing, tire size, brand preferences, and suspension specifics, adjustments like trimming the plastic inner fenders or modifying the body mounts behind the front tires may be necessary to prevent tire rubbing..
