The lower the ratio (higher the number), the quicker your car will accelerate and you will feel the difference in the "seat of your pants". Ford Performance’s 8.8" gears are the choice of championship road racing and drag racing teams around the world. Featuring OEM quality, a superior surface finish, hardening and strict manufacturing consistency, this gear set will provide you the strongest and quietest performance on the market today!

Please Note: Requires M4210B3, the 2015+ Ford Racing 8.8” IRS Ring and Pinion Installation Kit

*Will NOT fit earlier 8.8-inch straight axles found in previous generations.
*Will NOT fit 2015+ Mustangs originally equipped with a rear-end housing with factory installed 3.15 gears. 

Tech Tip: After installation of your new FRPP 3.55 Ring and Pinion Gear Set, you will need to adjust the rear axle ratio in the body control module in order to re-calibrate your speedometer. This can be adjusted for if you have previously purchased one of the new Ford Performance Power Packs for the 2015+ Mustang. Calibration support for 2022+ Mustangs is NOT available at this time.
