Description

Take your 2015+ Mustang to the next level with a Ford Racing IRS Ring and Pinion Set.

Ford Racing's superior surface finish, hardening, and manufacturing consistency provide the strongest and quietest 8.8" gears in the market.

Customer Reviews

Must have
The stock gears are meant for fuel efficiency and keeps your car out of its power band. When I put my 3.73s in it felt like a 30rwhp difference without the actual power out put. They should come this way from ford.

Essential Upgrade to your 'Stang
Upgrading the ring and ping ratio is one the bread and butter, essential upgrades on just about any model year Mustang. I saw huge 1/4 mile gains when I changed my '95 Mustang GT's rear rear from factory to 4.10 along with dramatically improved off-the-line performance and faster travel through the power band. Ford Racing gear sets are the highest quality, have never failed me, and delivery hundreds of thousands of miles of quiet performance.

Racing Gears To Wake Up Your Pony
I had a set of 3.73 gears installed by Steeda recently to replace my stock 3.15's and what a difference in performance. No longer does it take forever to hit my 2011 Mustang GT 5.0 automatic engine's powerband because now with the new gears I'm up there very quickly. These gears are a must have for those running highway gears and want more acceleration from your Ponycar.
