This specially formulated additive from Ford Racing 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 Racing's Friction Modifier is recommended for use in 1979-2026 Mustangs and is compatible with other brands of gear oil. One bottle is required for rear ends equipped with Ford Racing 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 Racing designed this modifier's formula to help cushion gears, which extends their life and prevents unwanted and unnecessary grinding and squeaking sounds.

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!
