Adventure Series upper control arms are built for improved suspension travel and added strength over the factory stamped units. Perfect for leveled/lifted applications where the arms function at an increased operating angle, these new adventure series arms use a repositioned ball joint mount to correct ball joint binding issues that lead to premature ball joint wear. The arms are fabricated from 1/8" steel plate, boxed and fully-welded with CNC machined ball joint and bushing cups. Arms are fully assembled for quick, easy installation right out of the box. Upgrade your Tundra's upper control arms to Adventure Series Upper Control Arms from Zone Offroad.
