Genuine Ford Fluid XL-3 Friction Modifier Additive - 4 oz.

Cheaper than box store. Used in my Ford limited slip differential. No chattering from the clutch pack.

Great product for friction on posi traction rearends.

I have a 2000 ford E350 ambulance with a 7.3 powerstroke diesel engine. 3 yrs ago I had to have the rear differential clutch pack replaced. I think he replaced the gears as well. He told me it will chatter a bit but would go away. It did chatter a bit but didn't go away. Recently it has gotten worse so I ordered 2x4oz. bottles of this stuff. It came in 2 separate boxes. I did order them alone due to other reviewers' warning about the smell and they weren't kidding. I also ordered a.big fluid syringe to "inject" it into the pumpkin. I have a prosthetic leg and some back issues due to a disc replacement surgery. This makes it hard for me to get under the truck so I took it to my friends shop. He had one of his young guys do the job for me. I won't lie, I also didn't want to touch the stuff. It stinks. Bad. The whole garage smelled of the stuff even still packed in the boxes. I put it in the side compartment of my van to bring it to the shop. I felt bad, the guy got it all over his hands and i.know it's going to be hard to get off. I hope he is allowed to sleep in the house tonight! Anyway by the time I got home the chatter seems to be.gone. I will have to do some serious sharp turns and reversing on an incline to know for sure, but it already is better doing normal driving with normal turns. I put 8 oz. In because that is what I saw as a recommendation for my differential. Anyway it's good stuff but it stinks. I left the syringe and boxes and empty bottles for him to dispose of!!

It works!

Excelente artículo

Requirement for Ford differentials. Pricy on here but delivers quick.

Great product at a good price

A must for your clutches

It does exactly what it’s intended and it’s genuine ford motor company and I used it on my F-150. Beware though it reeks. It smells like 10 year old burnt gear oil from a final drive condensed into a tiny bottle. Open a door before you open the bottle

This does exactly what it’s supposed to do and worked very well for my application. As far as performance goes, I have no complaints. The smell, however, is absolutely terrible and incredibly persistent. If you spill any, clean it up thoroughly and immediately, don’t just wipe it up. I spilled a small amount on my garage floor, wiped it up and figured that was good enough. It wasn’t. I should have mopped the area because the smell lingered for days. I’d also recommend getting the empty bottle out of your garage as soon as you’re finished with it. Good product that does its job well. Just treat a spill like a chemical emergency for the sake of your nose.
