2001 Explorer Sport Trac
I'm interested in a locker but the 2 websites i've been to didnt have an application for the sport trac. I have an 2001 sport trac. I checked Aussie and Powertrax but i've seen guys on here with lockers on their sport tracs. Any recommendations?

Aussie and Powertrax LockRight are pretty much the same design. And they are only made for open differentials.

If your rear 8.8 axle is a Limited Slip differential, then you need to get the Powertrax Noslip.

Lockers help you do this...

I have the Powertrax LockRight in my front and rear axles.
 






you can also check out the eaton e-locker.. they have them at 4wheelparts stores. they fit the 8.8' 31 spline diff
 






Those application charts stop at 2000 though. Is it the same?
 












whish ones of the Aussie Lockers model os theres for all ford trucks and years.

Even though their website only lists the 1st Gen Explorer years for the front axle, I'm sure they make it for the 2nd Gen front axles. They are both Dana35's, so it might be the same design. And of course all 1st Gen and 2nd Gen Explorers have the 8.8 rear axle and the inside of the differentials are the same. I believe my friend Txplates has an Aussie locker in the front of his Sport Trac.
 






A 1st Gen Explorer front locker will not fit a 2nd Gen front end. They are both Dana 35's but it won't work. I'm surprised that a Lock-Rite fit John's truck because I've read in several places that a No-Slip was the only one that would fit in the front of a 2nd Gen.

Read it where? I have never recalled reading anything like that. People with a Limited Slip rear differential have to use the Powertrax No-Slip. Unless they want to spend their money buying an open carrier and getting it installed.

The Aussie Locker is also only made for open carrier differentials. Here's where the Aussie Locker representative said they make it for the 2nd Gen Explorers...

The Detroit E-Z Locker is another copycat design of the Powertrax Lock-Right.

The Powertrax Lock-Right/No-Slip, Aussie Locker, and Detroit E-Z Locker are all lunchbox lockers. They install inside the carrier. And they are automatic lockers based on torque.

ARB and Eaton E-Locker replace the carrier and are selective lockers that can be turned on and off at will. But are more expensive than the lunchbox lockers.

It is time to post a product review on the only front locker available for our '95+ Explorers, the Powertrax NoSlip. For years we've waited on unfulfilled hopes and/or promises from corporations like ARB and KillerAxles, but one - and only one - locker is made today for our front differentials, the Powertrax NoSlip.

Hey, I just find the stuff. :salute:
If you have a Lock-Rite, great. Much less expensive than the No-Slip as I recall.
 






My ST is 4x2 so no front :( so, best option thats no ARB so expensive

Hey John you seem pretty knowledgable and know alot about the sport tracs. What is the stock axle/differential on the 2001 4x4? And how about the gears? Is stock 3.73? Is 4.10 the way to go with the locker?
 












The front is a Dana 35, the rear is a Ford 8.8", 31 spline.
Gears will either be 3.73 or 4.10 depending on factory options. Basically if your truck came new with 235/75-15 or 235/70-16 tires it will have 3.73 gears and if it came with 255/70-16 tires it will have 4.10 gears. Check the axle tag to be sure.
4.10's will be better for off-roading although you'd be better with 4.56's if you're going to install bigger tires. Going from 3.73's to 4.10's isn't really enough difference to be worth the expense.
My old '05 had 3.73's, I put 32" tires on it and off-roading was fine but I had to keep it in low range all the time. No biggie.
 






Now with the 4x4 models did you do 4.10s in the front and rear?
 






My truck came from the factory with 4.10 gears. But, like Johnny stated, it would be better with 4.56 or 4.88 gears.
 






Now with the 4x4 models did you do 4.10s in the front and rear?
Not necessarily. Again, it depends on the option package and tire size.
My old '05 was a base XLT 4x4 with limited-slip and 3.73 gears because it had the smaller 235/70-16 tires. This was because I purposely did not want the step bars that came with the XLT Premium package. The XLT Premium also included larger 255/70-16 tires and 4.10 gears to compensate. The Ranger I had before had step bars and the only thing they were good for was getting my pants dirty in the winter.

The puny tires were not a big deal because in less than two weeks I had done a TT and shackle lift, added 265/75-16 Bridgestone REVO's, and sold the tires that came on the Trac. :D
 






My stock tires are the 235/75-15s so i'm assuming i have the 3.73s (haven't looked yet). I want to do 33x12.50-15s on 15x10 wheels with tt and shackles. So i'm leaning towards lockers front and rear with 4.56 gears since you said 4.10 isn't that noticeable. I don't care to lose top end speed i would love more torque and acceleration instead.

What kind of mph would i get out of 4.56 gears? Would i at least get 80mph? I don't go over that much at all. But i was told 60mph is that true?
