Steeda Rear Subframe Support System W/ Alignment Bushing Kit Mustang 2015-2023

The S550 Mustang is notorious for rear subframe movement. This is because Ford uses soft Durometer bushings at all the subframe mounting points. Because of this, the rear subframe can cause wheel hop and even wheel misalignment. The Steeda Rear Subframe Support System prevents this from happening, by replacing the Durometer with precision-machined aluminum. This kit installs with basic hand tools and does not require any permanent modifications to your S550.

- OE Style Direct Fit

- Top-Notch CNC Machined Delrin Construction
- Aligns Rear Subframe to Chassis

The Steeda Rear Subframe Support System with Alignment Bushing Kit improves stability and control on your Mustang, for added traction, faster track times, and better overall handling. It is constructed from 6061 Machined Aluminum for a zero-flex solid rear end feel.

The Rear Subframe Alignment Bushings will also reduce any misalignments. From the factory they can be off by 1/2” - these bushings will eliminate that difference.

The Steeda Rear Subframe Support System requires no permanent modifications and won’t cause any increased NVH (Noise, Vibration and Harshness) to your Mustang. The included bushings are made from Top-Notch CNC Machined Delrin to ensure a perfect fit.
