Product BenefitsReduced deflectionReduced wheel hopNo NVH increaseEliminates alignment change under powerDecreases vehicle reaction timesRemoves bind in the suspension to allow it to move freelyBillet aluminum removal / installation tool includedLifetime warrantyFrom the factory, the 2015-2019 Ford Mustang features bushings in the rear control arm that we 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, we found that the factory bushings deflect so much that the rear tires can toe inward upon acceleration over 2 degrees!Our 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. Our spherical rear lower control arm will correct understeer under acceleration of your S550. You will notice increased chassis responsiveness upon installing our spherical bearings. If you drag race your GT, EcoBoost or V6 Mustang our rear lower control arm spherical bearings will play a huge role in eliminating deflection, ensuring your tires hook immediately upon acceleration. Our spherical bearings stop your S550 from building negative toe on launch. In addition to eliminating deflection and compliance of the factory bushings, our spherical bearings will also eliminate the spring rate of the factory bushing which does not allow the suspension to articulate up and down freely.Unlike other kits on the market, Steeda's includes a billet install / removal tool. The tool is compatible with either hydraulic and ball joint presses making the installation process painless from beginning to end.Our Steeda S550 Mustang Rear Lower Control Arm Spherical Bearings are manufactured in our state of the art facility in Valdosta, GA from 1018-steel and nickel-plated to prevent corrosion. We use high precision Teflon-lined bearings to ensure smooth operation and prevent bind. This also increases the bearing's life and minimizes 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.
