Our arms are meticulously designed and refined, meeting high standards. They are CNC machined from aerospace quality 6061 billet aluminum, bead blasted, anodized red, and laser etched with our logo. We use a larger FK 1.25" uniball with a PTFE liner for increased strength and mis-alignment, allowing for maximum wheel travel. Made in the USA, our arms are superior to cheaper imports. The uniball is adapted to the spindle/knuckle using model specific spacers machined from heat-treated stainless steel. No drilling or modifications are needed. The 1.25" uniball allows for a low profile press-on cap to resist the elements. We use larger and stronger FK 7/8" chromoly heim joints for additional camber and caster adjustment, eliminating flexing/deflection under hard use and braking. AN/Mil-spec hardware, including a single pinch bolt and secondary jam nut, ensures secure heim joint usage. Our V2 design increases usable wheel travel, corrects camber and caster, and eliminates weak factory ball-joints. All necessary hardware is included for installation. Our arms are designed for 1-3" of lift and are not compatible with vehicles equipped with electronic adaptive ride control suspension systems.
