Our 3.5 X-Factor System has all of the benefits of our Flex System but includes upper and lower control arms, front and rear. Our 3.5 systems allow you to run up to 33" tires and offers the ultimate adjustability. The system includes sport tuned triple rate coil springs front and rear for a excellent on road ride. Double adjustable lower control arms with a Monster Krawler Joint at the axle connection to allow a huge amount of flex and our vibration isolating Pro Flex joint at the frame. Front adjustable sway bar disconnects improve the off-road ability even further. Front extended stainless steel brake lines allow for greater axle travel and also firm up the brake system. The rear track bar bracket, which is made from a durable 3/16" thick laser cut steel, helps you easily recenter the rear axle. This is the most versatile system on the market today for the Wrangler LJ owner wanting to run 33" tall tires and improve off-road ability.
