These arms are meticulously designed and crafted using CAD and CNC machining. They are made from aerospace quality 6061 billet aluminum and undergo bead blasting, Type II anodizing, and laser etching for a sleek gun metal gray finish. The arms feature a larger FK 1.25" uniball with a PTFE liner for increased strength and misalignment, allowing for maximum wheel travel. They are made in the USA and are superior to cheaper imports. The uniball is adapted to the spindle/knuckle using model-specific spacers made from heat-treated stainless steel. No drilling or modifications are required. The arms also utilize FK 7/8" chromoly heim joints for additional camber and caster adjustment, eliminating flexing/deflection under hard use. AN/Mil-spec hardware, including a single pinch bolt and secondary jam nut, ensures secure attachment. The new V2 design improves wheel travel, corrects camber and caster, and eliminates weak factory ball-joints. These arms are designed for 1-4.5" of lift and do not fit the Bronco Raptor.
