Fits Mustang Super 8.8-inch IRS center section

Requires M-4210-B3 Mustang 8.8-inch ring-gear and pinion install kit

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.

Made in the United States at Ford's Sterling Axle Plant (competitors in our price range are primarily produced in China). OEM quality - our superior surface finish, hardening and manufacturing consistency provide the strongest and quietest gears in the market! Higher-quality gears means more-satisfied customers!

3.55:1 Ratio

3.15 ratio differential not compatible with 3.31, 3.55 and 3.73 ratio gears. Use differential M-4204-MT or M-4204-M
