Rockjock Rear Aluminum Johny Joint Control Arm Kit for 2021-2024 Broncos.

The Rear Aluminum Johny Joint Control Arm Kit provides you with durable, adjustable-length control arms to replace your factory control arms on your 2021-2024 Bronco. The adjustability of these control arms makes aligning lifted vehicles to get the perfect pinion angle specifications in check. Each control arm is CNC machined from 7075-T6 aluminum for excellent strength and corrosion resistance when hitting the trails. The control arms feature a smooth steel ball that pivots inside a proprietary urethane shell, providing over 30 degrees (per joint) of quiet, shock-dampening articulation. The design provides all these benefits without the excessive deflection found in soft rubber-based “flex joints.
