CB Engineering 2002 - 2007 Jeep Liberty KJ Rear Lower Control Arms. We have been a running a set of these over 3 years on one of our own KJ's with 33" and 35" tires . These replace the weak stock rear control arms. The stock control arms are made of thin steel tubing with rubber bushings that don't allow much articulation. Our control arms are made from 2" heavy wall DOM tubing that works with the factory sway bar that will last a lifetime. On the body mount side our control arms come with polyurethane bushings and custom stainless steel sleeves to work with the KJ control arm body mounts and metric bolts. Zerk fittings are standard on each joint. On the axle mount side, we use 2.5" Johnny Joints for better articulation and for more adjustment than stock arms. These adjustable control arms allow for over 1 inch of fine tuning of the control arm length to center the axle in the wheel opening when using larger lifts. These control arms are shipped bare steel for final coating by customer. These are designed for 0 to 4" of lift.
