From the factory, the 2015-2020 Ford Mustang features bushings in the rear control arm that were found to be less than ideal for putting all the 5.0L Coyote's power to the ground. The factory bushings deflect upon acceleration and steering inputs causing all sorts of handling issues that are less than ideal. In testing, Steeda found that the factory bushings deflect so much that the rear tyres can toe inward upon acceleration over 2 degrees!

The Steeda S550 Mustang Rear Lower Control Arm Spherical Bearings eliminates deflection of the factory bushing which is extremely important in any performance application. Deflection in the factory bushings can cause all sorts of negative handling affects. Steeda's spherical rear lower control arm will correct understeer under acceleration of your S550. You will notice increased chassis responsiveness upon installing Steeda's spherical bearings. If you drag race your GT, or EcoBoost Mustang Steeda's rear lower control arm spherical bearings will play a huge role in eliminating deflection, ensuring your tyres hook immediately upon acceleration. These spherical bearings stop your S550 from building negative toe on launch. In addition to eliminating deflection and complacence of the factory bushings, these spherical bearings will also eliminate the spring rate of the factory bushing which does not allow the suspension to articulate up and down freely.

The Steeda Rear Lower Control Arm Spherical Bearings are manufactured in Steeda's state of the art facility in Valdosta, GA from 1018-steel and nickel-plated to prevent corrosion. They use high precision Teflon-lined bearings to ensure smooth operation and prevent bind. This also increases the bearing's life and minimises the need for it to be replaced. The spherical bearings design, unlike most, will not increase NVH whatsoever so you are able to maintain factory ride quality.

We recommend these Spherical Bearings for drag racing applications especially.
