From 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.

Best Stop the hop mod

I have installed it all. IRS Alignment kit, IRS Braces, vertical links, toe link bearings, GT350R springs, and Steeda Fixed Valve shocks. All of them helped the suspension work so much better however there was always a grip and give in the rear end under load and the wheel hop still existed. I installed the Rear control arm spherical bearings and it is AMAZING the difference in the way it handles and the wheel hop is completely gone!. This is by far my favorite mod to date but I will say be careful pressing them in. They are steel and the control arm is aluminum make sure you have it good and square or you could do some damage. Thank you Steeda for another quality product.

I installed everything myself and, I must say, the car has been transformed.

I just wanted to thank Steeda for arranging acquiring new lower control arms for me equipped with this LCA bearing. I installed everything myself and, I must say, the car has been transformed. I already have the gambit of Steeda suspension parts (Ultralite springs, Pro-Action shocks, differential bushing inserts, IRS cradle bushing inserts, subframe bracing, sway bars, etc.) and this bearing took the car to another level. It felt sure-footed before in the back with all of those parts, but this LCA bearing took it to a level of refinement and tightness that is exactly the last bit I've been waiting for. And I didn't really experience any undesirable NVH; really not much of any NVH to report at all except, I guess, a much more "solid" and "connected" feel to the rear suspension. Here are benefits I've noticed, inclusive of regular daily driving, autocross, and a few spirited mountain runs: - Rear suspension seems to articulate more. I do not "tripod" nearly as often on steep inclines. - Knowing where my tires are at from a grip perspective is much easier to perceive now - My car seems to have greatly reduced its tendency (even in stock form) to rock for and aft slightly after stopping. - Wheel hop is gone. I cannot get it to wheel hop at all. Not even on the stock Pirelli tires. - The rear end is much easier to control, either to purposefully oversteer to bring the car around or to keep it following in line - The car feels much like a BMW M3 now; not unrefined in any way but tight and it's almost as if you can visualize the suspension working now vs. it being ambiguous I can write benefits all day, but I think the best compliment is that I've told everyone... get the LCA bearing installed. Just do it. It isn't as easy as bolting a part on, but it WORKS.

The rear just wants to GRIP and accelerate

The spherical bearings are also contributing to the newfound control and compliance of the suspension. I can tell that I can apply the power earlier in a turn vs. last week without these bearings and linear springs. The rear just wants to GRIP and accelerate.
