Overview

No deflection or NVH. From the factory, the 2015-2023 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 under hard or drag race applications conditions causing all sorts of issues that are less than ideal. With their spherical bushing construction, virtually all deflection is eliminated with Steeda’s LCA bearing design. The spherical bearings design unlike most, will not increase NVH (noise, vibration, or harshness) whatsoever so you are able to maintain factory ride quality.

Improved suspension performance. 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.

Install tool included . Unlike other kits on the market, Steeda’s includes a billet install / removal tool. The tool is compatible with either hydraulic or ball joint presses making the installation process painless from beginning to end.

First-hand note

FFP fits Steeda parts every week in Thousand Oaks.

— Why we stock Steeda

OE-style engineering, in-house manufacturing, race-proven on Steeda's own SCCA program.

Steeda has been engineering Mustang — and now Explorer, Focus, F-150, and Maverick — parts in Valdosta, Georgia since 1988. CNC-machined billet, proprietary CAD-driven suspension geometry, and a factory SCCA Majors road-racing team that runs their own parts on the track every weekend. When you bolt a Steeda part onto your car, it's the same part Steeda's own race cars run.

We carry Steeda because the fitment is right the first time, the warranty is real (lifetime on Steeda-manufactured parts), and the install instructions don't leave you guessing. Drop the car at our Thousand Oaks shop and our techs handle the fit-up — or order with confidence and run it yourself.
