With its massive 1.25-inch outside diameter and rugged OEM-style rubber bushings, it's built to handle anything the off-road throws its way. Durable CV Driveshaft: The factory shaft does not have adequate clearance once lifted and will cause damage to the Rzeppa joint if the driveshaft spins while the suspension is fully flexed or articulated. Rough Country's extended Front CV Driveshaft eliminates this issue allowing you to flex your suspension with more peace of mind! Adjustable Control Arms: The included Rough Country X-Flex Control Arms feature a massive 2.5in diameter body and huge 1.25 threads. The provided X-Flex Joints offer a considerable range, strength, and safety for off-road applications. Boasting an impressive range of motion, Rough Country's lower control arm flex joints are capable of a staggering thirty-five degrees pivot range. Easy Installation: We know you'd rather be off-roading than in the garage all day. That's why our lift kit is designed for easy installation, so you can hit the trails in no time.
