I do not have a limited slip rear end, is it posible to get one put
in. I get 1 tire on the smallest piece of ice and I can't move.

 

check out eatons detroit true track, I've used this on several occasions with great results

 

watch it if you get one, on the ice & snow, with all the torque that diesel makes, step on the pedal too hard one time & around youll. go.

 

I just looked at a site that sells them and I am lost.I think I will have to get more help from this great site or go somewhere and have it installed.

 

Defenetly has to be put in by a pro, but it's worth it. the spiral gear design keeps proportioned power on both wheels minumizing tail spin. and up here on the east coast, we need traction, especially during the winter.

 

I haven't been too impressed with my OEM limited slip.... Doesn't seem to ever lock up...

 

Fords limited slip should be called limited lockup. I have been very disappointed in mine. 2006 373 rear.

 

Mine works fine, if I start to spin a tire you can feel the other side grabbing and then when it starts to break loose the power transfers back to the original side. It is by no means a Detroit Locker, it is what it is, " a limited slip" rear end.

 

I finally had a Truetrac installed in the front dif in my 2007 SD F250 after researching and asking a lot of questions of anyone that had any experience at all with Truetracs and other limited slips or lockers. It is a 6.0 diesel, manual trans, hubs and transfer with 2.73 gears in the difs ( the rear end is a stock limited slip that works OK for now ). I didn't have the time to screw around with it or the inclination to buy some of the tools needed for the job, so I just took it to Donny's 4X4 here in Reno and had them put it in. It only took them a morning of working on it and I ahd it back. Parts, labor and all was $982.00 installed and I hate having someone else do work I can do myself, but in this case, I coudn't avoid it if I wanted it in there right away.

And the verdict is....it works great. I have had the thing out in the snow and it just GOES! It is now an actual 4X4 and not just a two wheel drive that slips and slides all the time. It pulls very well on the slippery stuff and goes through the snow VERY well. In normal hard surface conditions I just disengage the hubs and put the transfer in 2 wheel so the fron dif doesn't turn at all. When it is all engaged I don't feel any sort of pulling to the side and it does not tend to go straight like a locker will. The only time I can tellthat the front end now has the truetrac in it is if I have the steering ALL the way to the stops in a tight turn on really slippery stuff or if I happen to get on some dry pavement. Then I can feel the front wheels kind of tugging at the steering, but it is in no way a bother.

So far I really like it and believe that if the stock limited slip in the rear end ever seems to be getting weaker (or even if I just happen to have the extra money), I will install a Truetrac in that, too. I would highly recommend the Truetrac to anyone that drives their 4X4 mostly on the street and isn't a hardcore rock crawler that needs a locker.

I've got an OEM with 4.10's & it works great. It only locks up when it has to. I pull a 37 ft. 1/5th whl RV trailer & it's kicked in when neeed. With out the trailer & in the rain turning corners it'll lock up. When it was brand new, 200+/- miles it was racheting & Ford drained the diff. replaced the oil & added a modifier & with in a week the racheting quit & it's been great ever sense.

 

You can tune your OEM LS by varying the amount of friction modifier in the diff fluid.

 

I've had my 05 F-250 for over a year now and I was told that it had a LSD but I never really knew the dif between dif's. All I knew was my 88' F-150 NEVER got stuck and this truck slips all the time!

After a bit of research I find out that in fact I have a 3.73 Open Dif... WTF!! (drivers' door 'AXLE' code 37)

Well now that I know why this truck has no traction I too would like to rectify this.
Any suggestions?! Cheaper is better....

 

I'm a big True Trac proponent unless you use your truck rockcrawling. The True Tracs I've had always pulled, even with a wheel in the air, so I don't see any reason to use anything else.
