I am about to do a gear swap and found a pretty good deal on an Eaton Posi. The truck is a daily driven one but i do occasionally go to the drag strip. I'm going from 3.55's to 4.10's. I think i've heard good things about the Eatons but i may be wrong. So, my question is is how good is an Eaton posi.??

thanks

I presently own three Ford trucks. One has Auburn (1979, F-150). One has OEM Trac-loc (99, F-150) and one I will install my new Eaton-Posi in within the nest 6-weeks (1994 Ranger, with 8.8", 28-spline).

Personally, I have had good luck with the Auburn (Pro series). I had an experience this weekend that let me know the Auburn hooks up tight. I was driving thru some deep dry ruts in a field--turned vehicle to the right to climb out of the ruts--all of a sudden diff. locks up and I am sliding side ways and truck is still pulling (I was in low gear). This did not suprise me; however, I have owned this F-150 for 15 years (had the Auburn in it for 8 years). I know the trac-loc would not have acted like this. I drove this vehicle for 7 years with OEM trac-loc.

I am anxious to see how the Eaton-Posi will work in the Ranger. I am purchasing ranger from my Uncle's Estate. Don't want to install the Eaton, until title is in my name.

 

Is there anyone else out there who has any experience with or heard about Eaton posi's? Thanks for replies.

At my regular vocation, I have customers purchase Eaton-Posi (usually about one or two per month). No complaints ever on the Eaton-Posi. try: http://www.eatonposi.com to view eaton traction products. Be sure is you install any type of friction plate (or cone type diff., like an Auburn)--ADD FRICTION Modifier to your lube.

Recently, I spoke with a Rep. @ Eaton-Posi and related that there is no application for the new E-locker for the 9.75" Ford diff. (if you have a 5.4L Triton). She was very well informed with the product she represents and She assured me that Eaton Corp. will be producing an E-Locker for the 9.75", rear diff. next year.

 

before you get set on an eaton, think about a detroit locker limited slip. i have had several people recommend it above all others, including NEAL newman. i dont have any experience with one because my truck has factory installed LS, but one week on popular hot rodding TV dean and cam did a segment on rear ends, and they recommended the detroit locker over the rest.

 

Anyone suggest a LS in the front axle? I am also swapping gears, and while its open.....
