Locker for 2wd
I have a 91 F150 2wd and looking to install a locker and 31"x10.5x15 tires for light off road duty. I'm tired of the one wheel spinning. I don't mind a locker for street use, I've had other lockers and full spools before. My question is the tag on the rear differential says:
S844A
3.55 88 1E22
I take it has 3.55 gears, but what spline count come on these trucks? Also carrier pin diameter 3/4 or 7/8"? I just want to make sure I get the correct locker as their appears to be some options.

The spline is 31. I don't know about the carrier pin diameter.
I would go with a Ford traction lock or Auburn limited slip. The Auburn I had in my old truck was really nice.
I hate lockers , unless they are on vehicles that rarely see the pavement. Even then, I don't think I'd ever get one again. I had one once, and it was annoying. The jerky behavior was enough for me.

The Powertrax Lockright will install inside the existing open carrier in your axle(after you remove the spider gears), and I have seen one of these perform quite well on a street driven truck.. very little sign that it was there except for an occasional clunk from the rear end under certain conditions.

I thought it would be 31 spline. I was looking at a limited slip, that is another option. I dont mind a locker on the street, they are jerky and have different road manners. They do horrible in snow condition from my experience. Thanks for the ideas.
Money is on the tight side and why I was leaning towards lock right or aussie locker. A little easier on the wallet. Maybe in a few years when economy is better I will upgrade to 4x4, but right now a little minor upgrade would help.

Good question, I wonder too.

I drive primarily on pavement and gravel and on rare occasion a farm field
No recreational off roading
But I feel super vulnerable with my open carrier
Something like this sounds like my solution assuming the long term on road use is ok

I have a 92 4x4 with 3:55's. I would like to get a locker but as TexasGuy said
I don't want that issue, and the cost of Air Locker is too high for me, even though it gives the best of both worlds. This is what is said about the "POWERTRAX® EXTREME TRACTION LOCKER" in their ad.

It's supposed to be better than the PowerTrax Lock-Right. But, for me. I will wait untill I hear from someone who has one to see what they think about it's performance. Just my 2 cents. If you do get one, which ever you choose please let us know what you think. I hope other guy's who have a locker will also post their Pro's and Con's

This is the type of use I want one for. When I go up to our stable it sit's up on a hill so I use the 4 wheel drive. But going across the field with just 2WD with an Open Diffy is terrible if the ground is wet,,and forget going up slopes or a little hill.

It works quite well. I've had one in my truck for about 10 years. They operate smoothly and quietly. Its just fine for most applications, except for maybe a hardcore trail rig. I also lime that the clutch packs are replaceable so its a rebuildable unit.

It gets plenty of hate, but I like Ford's limited slip that comes stock in these trucks. I typically put 2 bottles of friction modifier in the rear end when I change differential fluid.

Like if one wheel has little to no traction
How much of the torque stays with the other wheel?
