Take your 2015+ Mustang to the next level with a Ford Racing IRS Ring and Pinion Set.
The 8.8" rear end has been the standard in performance since its introduction in the Mustang in 1986 and Ford Racing is the manufacturer of choice when it's time to performance build your axle.
Ford Racing's superior surface finish, hardening, and manufacturing consistency provide the strongest and quietest 8.8" gears in the market.
When you're purchasing a new 8.8" gear set make sure your bearings and shims are up to the task with Ford Racing's High Performance Installation Kits.
Note: If you have a OE 3.15 differential you must also upgrade your differential to 161-M-4204-MT or 161-M-4204-M in order to properly install these gears.
