Super-Flex 2 adjustable front upper control arms for TJ/LJ Wranglers and XJ/MJ/ZJ Cherokees. Upper front adjustable control arms allow adjustment in pinion angle and caster. All Super-Flex Control Arms feature our rebuildable spherical bearing assembly. This unit is greasable and extremely quiet due to the non-metallic races. A Super-Flex joint allows extra flex for off-road prowess, yet does not sacrifice on-road handling or long term durability. Adjustable range: 15.25 inch - 16 1/8 inch. Sold as a pair.
