Product details
RockJocks rear upper control arms for JT Gladiator vehicles provide length adjustability via RH/LH threaded adjuster ends, allowing pinion angle to be adjusted after the installation of a suspension lift without either end of the arm having to be removed from the vehicle! Additionally the adjustable feature of our arms allows your vehicle to be upgraded to different lift amounts without having to replace the control arms in the future. Arms are fabricated from 1.625 in. o.d. x .250 in. wall DOM steel tubing. For maximum articulation, arms feature forged 2 1/2 in. Johnny Joint rod ends on both ends with 1 1/4 in.-14 RH/LH threads and jam nuts. Arms are finished in semi-gloss black powder coat and the forged ends are finished in gold zinc plating.
