Product Description

FRICTION MODIFIER FOR CLUTCH-TYPE LIMITED-SLIP DIFFERENTIALS

Motorcraft XL-3 Friction Modifier is identical to Ford Racing M-19564-A Friction Modifier

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.

When making a turn, the outer wheels of your Mustang must travel faster than the inner wheels. It is up to the differential to act as a balance arm, establishing constant equilibrium of torques and forces between the left-hand and right-hand driven wheels. In standard (or open) differentials, power is directed to the wheel offering the least resistance. This works well when making a turn, but in a situation where one wheel is lifted off the ground, it causes the suspended wheel to turn while the other remains motionless.

Limited-slip (or positraction) and locking differentials are traction-increasing devices. Locking differentials transfer all available torque to both wheels. The teeth of the spider assembly engage with those on the locker clutch, causing both axle shafts to operate as one. Locking differentials don't allow one drive wheel to spin while the other remains stationary. Instead, they keep both wheels in drive mode, but unlock to permit different wheel speeds when turning. The engaging and disengaging of the teeth on automatic locking differentials often causes a banging and clunking sound. Manual locking differentials usually use an electric motor or vacuum diaphragm to engage the locker, reducing this noise.

Limited-slip differentials allow different wheel speeds when turning, but when one wheel loses traction, greater torque is transferred to the wheel offering more resistance. Limited-slip differentials make use of friction between clutch plates, as opposed to the meshing teeth employed by locking differentials. Transferring less torque per side, limited-slip differentials are generally smoother and quieter than locking differentials, but still sometimes "chatter" when transferring torque to the wheel with traction.

In your Mustang, a friction modifier additive is necessary to reduce chatter. Ford Racing friction modifier is designed to eliminate gear-housing chatter in your Mustang.

Due to Hazmat regulations, lubricants/fluids cannot be shipped to APO/FPO addresses.

  a must have for trac loc
By on 8/18/2014
after recently changing the lube on my freshly rebuilt diff and trac loc rear end the car began making loud groaning noises whenever I turned a corner , even though the synthetic lube used was recommended for limited slip rears. I added the Ford friction modifier and within a few miles all was smooth and quiet again.

Yes, I would recommend this item to a friend!
