Powertrax Info
For those looking for some info on the Powertrax Differential units, I've had a Powertrax No-Slip for about a year now. I have a 97 x-cab 4x4 with a 3.08 rear, I soon found the open rear to be a major drawback for my truck. God forbid I gave it any gas at all around a turn in the rain, spun like crazy. So I bought my Powertrax unit from a guy who got it for his truck which was stolen before he installed the unit. I installed the unit in about an hour in the driveway with hand tools. I used the Ford 75W140 gear oil rather than the aftermarket 75W90, 50% less viscosity at high temperature is too much for me to give up. The unit does pop around turns for about the first day, they say 50 miles or so. The unit will pop very rarely now after 8Kish miles.
The traction difference is amazing. There is NO differentiation in the wet or mud ;-) Both tires get full power all the time. The inside tire does scrub any time I give it gas around a tight corner, kind of annoying but I learned to adjust my driving. Since the Lock Right is supposed to be a much harsher unit, I would recommend the No-Slip to anyone looking to upgrade their open diff to get some serious traction.
I was just mudding this weekend with a buddy in his jeep CJ-7, the F150 was able to go anywhere and everywhere the Jeep could.
If anyone has any questions about the install or what have you, let me know.

I'm sure you will be happy with it. Do you have a 4x4? If not you will appreciate it even more, one wheel peal sucks.
I have learned to give the truck some throttle before entering a turn and then let it coast through. Otherwise I scrub that inside tire like crazy. I know that is exactly how it is supposed to work but it can't help the treadwear that's for sure.
Ripping donuts in the mud now that is fun, seeing 2 big rooster tails coming out the back.

ttimoney,
Good post, exactly my opinion.
I have the two-wheel drive and the difference off the line is amazing. I too get that annoying scrub if I give any gas at all into a corner. I also will get a chirp when I hit second at moderate acceleration after turning. That is because of the 4:30 gears and the Transgo kit kicking the rear into lock-up but I can live with it.
Annoys my wife, another plus
