Lower Adjustable Control Arms TJ/XJ/MJ/ZJ/LJThese heavy duty replacements for those flimsy stock control arms come with Johnny Joints for flex, smooth ride, and to allow adjustments in caster and axle position. The links themselves are built from the same bulletproof 7075 Aluminum alloy as our long arm and steering kits. Good luck hurting them! Our T-Rex short arms replace the stock lower arms on the front of LJ, TJ, XJ, MJ, and ZJ Models, and the rear lowers on TJ and LJ models. Price shown is for a pair of lower control arms, click the box above to add a pair of uppers as well. Our upper links use Johnny joints at the frame, and SFR clevis ends at the axle. These use a larger than stock 7/16" bolt at the axle end. We recommend swapping to JK upper control arm bushings, but you can drill the stock center sleeves as well. Please allow 7-10 business days for order processing.
