This specially formulated additive from Ford Performance works to provides smooth operation of clutch-type limited-slip differentials in your pony's rear end. This modifier comes in a 3.8 fluid ounce bottle, which is normally good for one full application. Ford Performance's Friction Modifier is recommended for use in 1979 to 2020 Mustangs and is compatible with other brands of gear oil. One bottle is required for rear ends equipped with Ford Performance traction-lock (Trac-Lok) units. If you're planning on a rear end fluid flush or need to swap some gears, be sure to properly prep your differentials with this modifier.

Ford Performance designed this modifier's formula to help cushion gears, which extends their life and prevents unwanted and unnecessary grinding and squeaking sounds. If you've noticed an increase in noise after a rear differential gear swap, take some time to stop and properly prep the new gears. This little bottle is a must-have for any performance pony or any race vehicle--grab a few extra to keep in the tool box at home and on the track!

Please Note: This friction modifier is to be used by Mustangs with Clutch-Type Limited-Slip Differentials only (1979-2020 model years).
