# SPL Parts 15-21 Ford Mustang S550 Rear Toe Arm Bushing

S550 Mustang Rear Toe Arm bushings replace the mushy factory bushing in the rear knuckle. This replacement bushing removes the large amount of deflection that the toe bushing sees under heavy load. For reasons unknown, the Ford Performance replacement bushing for this location is wider than the regular Ford bushing, not allowing our Toe Arm, which was designed for the OEM knuckle, to fit over the Ford Performance bushing. If you plan on upgrading your suspension with SPL Parts, we suggest sticking to our catalogue to ensure proper fitment. These pair fantastically with the Rear Toe Arm (RTA S550) to remove weight and decrease deflection in your rear suspension. Sold as a pair. Made in the USA. Application: 2015+ S550 Mustang

-   Reduce body roll and improve handling on your 2015+ Mustang by correcting the front roll center using the included 1/4" and 1/8" spacers. Proudly made, engineered, and assembled in the USA.
