# RockJock JK Johnny Joint Billet Aluminum Control Arms Front Lower Adjustable Pair

RockJocks high end, billet aluminum Johnny Joint front lower control arms for JK Wrangler and JK Wrangler Unlimited vehicles are a beautiful addition to any JK build and provide length adjustability allowing pinion angle to be adjusted after the installation of a suspension lift! Arms are constructed of CNC machined billet 6061-T6 aluminum and are finished in black anodizing with machined highlights. 4130 chromoly skid plates bolt on so that they may be replaced in the future if they are damaged. Arms are double adjustable via right hand/left hand 1 1/4 in. thread Johnny Joint rod ends and grade 8 pinch bolts at each end. NOTE: These arms will work with 37s on stock width axles and a 4 1/2 in. backspace wheel. If used with larger tires, you will need to go to a wider axle or wheel spacers. Arms are a minimum of 3/8 in. longer than stock and must be used in conjunction with adjustable upper control arms.
