UPR Billet IRS Differential Bushing Insert Kit for 2015-2018 Mustangs. 4 piece CNC Billet kit eliminates the movement the factory rubber bushings. The stock rubber bushings have voids to allow the differential to move around which translates to wheel hop under hard acceleration. By filling these voids it reduces wheel hop and improves the overall handling of your car without adding any noise, vibration or harshness to the ride.

Made from 2024 Billet Aluminum instead of the standard 6061 that our competitors use adds strength to a critical part of the suspension. 2024 has a tensile strength of 68k psi compared to 45k psi or 51% stronger than 6061.
