    UPR Billet IRS Subframe Bushing Cradle Lockout Kit for 2015-2019 Mustang S550s. 10 piece CNC Billet bushing lockout kit eliminates the movement within the factory rubber bushings. The stock rubber bushings have voids to allow the rear to move around which translates to wheel hop under hard acceleration (and wheel hop kills halfshafts). By filling these voids it nearly eliminates wheel hop and improves overall handling of your car without adding any noise, vibration or harshness (NVH) to the ride quality.  These UPR Billet IRS Subframe Bushing Lockout Kits are made from 2024 Billet Aluminum instead of the standard 6061 that others may use, which adds strength to a critical part of the suspension. 2024 has a tensile strength of 68k psi compared to 45k psi 6061 (or 51% stronger)
