BMR 15-17 S550 Mustang Premium Rear Lower Control Arm Bearing Kit - Black

If you're looking to get more out of your 2015-2020 Ford Mustang's rear suspension, this kit from BMR Suspension is a solid choice. It directly replaces the stock rubber bushings in your rear lower control arms with heavy-duty spherical bearings. While the factory rubber is good at soaking up vibrations, it can allow for too much movement when you're putting power down, leading to wheelhop and less stable handling.

These spherical bearings are designed to eliminate that deflection. By using large, 1-inch bearings pressed into machined cups and secured with snap rings, BMR ensures the control arm moves precisely where you want it to, transferring power to the wheels instead of letting it get absorbed by squishy rubber. The kit also includes CNC-machined billet aluminum spacers for a precise fit. This setup drastically reduces lower control arm movement, which can make a notable difference in how your Mustang launches and handles, no matter your driving style.

This kit is a great way to firm up the rear end of your S550 Mustang. Keep in mind that by reducing bushing deflection, you might notice a slight increase in road noise or vibrations compared to the stock setup, but the improved stability and power transfer are often well worth it for performance-minded drivers.
