Mustang Gears & Rear End Gear Kits

A set of Mustang gears or ring and pinions gears should be on the very short list of things to do for your Mustang. Adding a rear gear set to your 7.5" or 8.8" Mustang rear end will improve acceleration, performance, & sometimes even gas mileage! While choosing what gear ratio to go with can be hard, we make the buying decision easy by keeping Mustang rear gears in stock at ultra low prices. Our 1979, 1980, 1981, 1982, 1983, 1984, 1985, 1986, 1987, 1988, 1989, 1990, 1991, 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013 to 2014 Mustang ring & pinion rear gear sets come from Ford Racing (FRPP) & Yukon so the quality is second to none.

Mustang Gears & Rear End Gear Kits Tech Info

Ring Gear: The Mustang ring gear bolts to the carrier and is driven by the pinion gear.

Pinion Gear: The Mustang pinion gear turns the pinion gear, transferring power from the driveline.

Shim: A shim is a thin piece of metal that is used to either adjust the fitment of other parts or take up a gap.

I.R.S.: This stands for “Independent Rear Suspension”, a housing which allows the left and right axles to move up and down separately from each other. 99-04 Mustang Cobra's are equipped with IRS systems.

Crush Sleeve: This is a collapsible spacer which installs on your Mustang's pinion and preloads the pinion bearings. Crush sleeves are not reusable and must be replaced if the pinion nut is loosened or removed.
