Converting the front of a mid-arm JK to long arms changes how the axle travels. The Front Four Link Long Arm System supplies upper and lower Duroflex control arms with frame-mounted lower brackets, which keeps wheelbase measurements consistent through the suspension cycle and improves pinion angles. The joints are vulcanized elastomer, self-centering and enhanced with Kevlar fiber. Choose the Upper Arm Mounts option, bolt-on or weld-on. Installation starts with cutting off the factory front control arm brackets, and the kit ships as one complete system with all required hardware included.
