Description
The Foutz Motorsports F-150 Lower Arm Pocket Replacement Kit helps strengthen the lower pockets where the lower control arm attaches.
This area takes the brunt of hard hits during aggressive off-roading, especially when the truck has aftermarket bumper upgrades. When exposed, the edge is more prone to rolling or ripping off on impact—leading to structural damage or complete failure.
