I just had a set of Richmond 3:89 gears set up in my 9" rear and was wondering if I should add the Ford friction modifier lube.
What does it do?
Its so cool to be able to put both tires up in smoke at will now.
It helps the clutches so they don't grab as much when they are breaking in. I just did my rear with 3.70's and the trac loc. Everyone I talked to said the same thing, "put it in" it will save your clutches and they will last longer. You will still get the traction on both sides. 1 bottle with the gear oil. They said make sure you use the gear oil for the limited slip, and "don't use synthetic" it will destroy your clutches......
They are right,the modifier makes it turn quieter but will not affect a full scale hard run,I run it in my 8.8 with 3.73 gears and still hook both tires hard,just rebuilt the Traxloc,here's a hint tho,use an F-150 S spring instead of the stock one,it's stiffer and makes the clutches grab harder.

Well I guess I will put it in.The friction modifier that is.Its too late now to put the heavier spring in but thanks for the tip.
I am eventually going to have a complete currie or Moser or whoever rearend built to handle some hard launches since I only have 28 sline stock axles for now
so this rearend is kind of a crutch for now while I still run on the street.The trac-loc will be replaced by an auburn locker or something similar.
