CB Engineering 2005 - 2010 Jeep Grand Cherokee and Commander Rear Lower Control Arms. 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 1/4" wall DOM tubing that will last a lifetime and will never break. On the body mount side our control arms come with polyurethane bushings and custom stainless steel sleeves to work with the unique width of the WK and XH control arm mounts and metric bolts. Zerk fittings are standard on all each joint. On the axle mount side we use Johnny Joints for better articulation 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 available in two finish options bare steel and our 2 Stage Powder Coat for extreme protection. These are designed for 0 3" or 4" to 6" of lift with Superlift Brackets. 7" to 8" of lift a longer arm needs to be used. Bare arms are usually kept in stock, Powder Coated arms may have a 2-4 week lead time.
