The FRPP ring and pinion gear sets are available in multiple gear ratios for your Ford 8.8 rear end. Each gear set includes the pinion and ring gears, crush sleeve and pinion nut. Here at LatemodelRestoration.com we know that you need more than just the gears to finish off your installation. That is why we are the originators of the Mustang Rear Gear Kits!

Each of our Gear Kits features all the needed parts for you properly install a new set of gears in your Mustang! We include only the best components in each kit. They begin with your choice of Ford Racing Rear End Gears (see below of available ratios) and then we throw in Ford Motorcraft Friction Modifier, Royal Purple Max Gear 75W-90 gear oil and finish it off with a master bearing & shim kit.

Installation of your new ring and pinion gears should always be done by a mechanic with a good working knowledge of rear end gears! We put together this how to installation video to help walk you through the install process. If you feel at any point this removal and installation process is above your mechanical skill level -- you aren't alone. Make sure you take your Mustang and new gears to a good trustworthy shop with experience installing Ford 8.8 rear end gears. This video will help you have a better understanding of what questions you should be asking and what to look for in the installation!

Changing your rear end gear ratio will require you to recalibrate your speedometer. For 83-95 Fox Body and SN95 Mustangs, you will need to replace your speedometer gear to fix your speedometer. Click the following link to see our speedometer gear calculator to properly select the correct speedometer gear - http://www.latemodelrestoration.com/products/Mustang-Speedometer-Gear-Calculator . If you have a 1996 to present Mustang your best fix is to pick up a SCT tuning device such as the SF3 handheld tuner to correct your speedometer. You can see our full line of SCT Tuners and Tech Videos here - http://www.latemodelrestoration.com/products/Mustang-SCT-Tuners .

When replacing the ring and pinion gears on your Mustang don't forget to pick up a traction lok clutch repair kit or new traction lock differential. The clutches in the factory unit wear out over time -- especially with aggressive driving. Save yourself time and money by replacing these when installing new rear end gears!!!!
