Our updated design features a billet aluminum cover for the uniball, providing protection against dirt and contaminants. The cap is press-fit and sealed with an O-ring. Our Camburg upper arms replace the stock ball-joint with a larger 1.25 uni-ball bearing, increasing wheel travel and durability. We also improve caster and camber curves for better alignment and handling. Our arms are designed using CAD/CAM software and manufactured in-house with precision welding and CNC machining. They come with polyurethane frame pivot bushings, grease-able zerk fittings, 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 fit 6 lug model trucks.
