Enhance Performance with Ford CM19546A1 Friction Modifier Review

Great product for any Ford with limited slip differential. The only bad thing was that it never came with a nozzle so you can actually fill your diff with fluid.

A handy source for quality OEM friction modifiers for my new limited slip differential. Originally used with a Ford LSD 8.8 driver with 31 spline and carbon fiber couplers on the 2003–2004 Ford Mustang svt Cobra.

Place this along with Lucas Gear Lube on the back of a 2013 F-150 that before this service for the world sounded like it was about to explode. Other lube changes with other products made no difference, but this combination completely solved the problem.

ordered for 8.8 Limited Slip Clutch (Trac-Lock) to eliminate clutch vibration. worked 100% as expected. Please note that even if the bottle is sealed and packaged, the odor will penetrate through several layers of packaging. DO NOT order/ship items that retain odors such as B. fabrics or food.

Excellent additive for older cars with blurry, noisy differentials. There are other uses reported by various commenters - read what they say. Although it is packaged in a secure container, the smell oozes from the bottle and you and your family will quickly find out when you bring it home. Keep it in a garage or outbuilding to avoid odors. (A strong smell means it's working very well.)
