Ford Performance's specially formulated Friction Modifier is a must-have for any gear swaps or fluid flushes on your foxbody Mustang! The purpose of this modifier is to make your gears operate smoothly and quietly. This means less noise and increased durability of your foxbody's rear gears.
It is compatible with other brands of gear oil, and it's important to note that one bottle is required for rear ends equipped with Ford Performance traction-lock (Trac-Lok) limited slip differentials. Be sure to keep one of these on hand, but not on your hands because this stuff is ultra-smelly.
-- 3.8 fl oz Bottle
-- Extends Gear Life and Reduces Wear
-- Ford Performance part number M-19546-A1
IMPORTANT: Only for use with rear ends equipped with clutch-type limited slip differentials.
