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 with our Camburg logo. The larger FK 1.25" uniball with a PTFE liner provides increased strength and mis-alignment for maximum wheel travel. The arms are made in the USA and are superior to cheaper imports. Model specific spacers machined from heat-treated stainless steel adapt the uniball to the spindle/knuckle without drilling or modifications. The 1.25" uniball allows for a larger bolt with a low profile press-on cap to resist the elements. The use of FK 7/8" chromoly heim joints allows for additional camber and caster adjustment while eliminating flexing/deflection and binding. AN/Mil-spec hardware, including a single pinch bolt and secondary jam nut, ensures secure heim joint performance in off-road conditions. The new V2 design increases usable wheel travel, corrects camber and caster, and eliminates weak factory ball-joints. All necessary hardware is included for installation. These arms are designed for 1-3" of lift.
