Ford Performance 3.31 Gear Kit
Improve your Mustang's acceleration and eliminate gear whine with this complete 3.31 gear installation kit! Specifically designed for the Mustang 8.8 rear end, this kit includes a Ford Performance 3.31 ring and pinion gear set that is made in the USA as well as the additional parts needed for proper installation. Also included are two bottles of Royal Purple 75W140 gear oil and one bottle of friction modifier. Ford Performance built this 3.31 gear kit with everything you will need to make the installation of the ring and pinion gear set as painless as possible.

Ford Racing Friction Modifier
Ford Racing friction modifier is a specially formulated additive to provide smooth operation of clutch-type, limited-slip differentials. One bottle of friction modifier is required when changing the gear oil in rear ends equipped with Ford traction-lock units.

Royal Purple Max-Gear Oil
Royal Purple Max-Gear gear oil is an ultra-tough automotive gear oil. It is designed to maximize power and provide unsurpassed protection to heavily loaded gears. It makes gears run smoother, quieter, cooler, and longer without overhauls. Max-Gear outperforms other gear oils because it combines the highest quality synthetic oils with Royal Purple’s proprietary Synslide additive technology.

Installation Note
  • Although the Royal Purple gear oil has a friction modifier mixed in, it is still recommended that you use the bottle of Ford Performance friction modifier to supply your 8.8 rear ends with the proper amount of modifier.
  • LMR recommends the 75W140 viscosity for all 1986-2014 8.8" differentials as it is appropriate for most climates, fuel economy, and performance.
  • PVTKF8.8-B 2012 GT500 high-torque rear pinion bearings included as an Upgrade for Factory Components and works on all 1986-2014 Mustang 8.8 differentials.

Application
  • Fits 1986-2014 Mustang with 8.8" Rear End
