FORD Racing 8.8" IRS Ring Gear & Pinion Set, 3.73:1 (2015-2016 Mustang GT)

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 hop-up your axle. The ring gear and pinion has been redesigned for the 2015 Mustang IRS center section and Ford Racing is first to market with a selection of gear ratios for the Mustang enthusiast.
