Buy a lsd for a 7.5" or buy a JY factory lsd 8.8" ?

[Dirtman]

I desperately want a lsd in my 2wd ranger. A tru track for my little 7.5" cost about 500 with new bearings and such. An 8.8 from a fx4 or any 8.8" lsd ranger in the scrapyard is 200 but will need new brakes and maybe clutches ect so price ends up almost even. I have no plans of offroading or abusing my 2.3l truck, i just want the extra traction in the snow.

My current axle has only 65k, has brand new brakes and stops fine, and the 7.5" is plenty strong for what I do. It is also a 4.10 and i will not go with anything less since the 2.3 is gutless to begin with.

I know of no factory 7.5" lsd axles (do they exist? If so what vehicles should I check?) so what do you think is the best option... Install the new lsd on my good clean 7.5" or rebuild a junkyard 8.8" with factory lsd? The explorer swap is more work than its worth. I want direct complete bolt in axle from a ranger, no rear disc swap nonsense or flipping perches. Or just do a direct bolt in lsd carrier for my current diff.

I got an axle from craiglist from a guy parting out an Explorer for $100 and I pulled it.

You don't want an Explorer axle but maybe find a Ranger in the same situation that is being parted out.

Been looking for 3 years. Tired of waiting, there's never anything local. Junkyard is full of lsd 8.8's for 200 (u-pull price for any rear axle). havent checked gear ratios though... Need the 4.10 and that's rare from my understanding except in the 4 cylinder autos which dont get an 8.8 anyway. Even a part out truck would still almost guarantee needing at least partial rebuild so still dumping money in after the fact.

did you try Mustangs? housing is different, carrier should be the same. not sure if Aerostars would be the same, or ever came with lsd.

Yukon lists a Dura-Grip for the 7.5,,$406 at Jegs.

7.5 Trac-Loks are out there.

Try www.car-part.com

Stangs went to 8.8 in '86.

The V8's did anyway, never really looked into the others.

Only the GT cars. Anything with a 4 or 6 cylinder still had a 7.5.

There are a couple 7.5” LSDs out there. I think Torsen still makes one. They aren’t cheap though.

I'd just get the locker for the 7.5. "The devil you know..." and all

Until 2010 or so, you could get Ford 7.5 trac locs on Mustang websites because the V6 cars still used the 7.5. I haven't seen any new ones for sale online in a few years, but I haven't been looking either. It might be worth a trip to your local dealer to see if they could get one, and how much it might cost. I've got one that is handling my sticky 295 tires and supercharged 3.0 just fine so far. I think it was around $200.

Some Rangers came with a 3.73 LSD 7.5 rear differential. I know my 89 STX had one and it was standard on the 4WD STX's. I am sure that was an option on other Rangers too. I know finding a old STX may be difficult and a Ranger with LSD 7.5 may not be easy either but they are out there.

Just look for any non 4.0 ranger/aerostar with a letter in the axle code.

Aerostars ran coils, but spring perches can be welded

If your are going to weld perches just go Explorer, they are 10:1 to Aerostars in yards.

OP just wants a drop in though.

Where do you live? I have an Explorer axle with 4.10 LS and discs already set up for a Ranger.
