Samurai 86-88.5 lockrite locker

[Phizinza]

I found this one, looks like it is a Vitara diff?


And the side gears have a ring around them, but are they the same/will they fit the Powertrax 1510 locker?

It will physically fit in the carrier, but the first time you jump on it in a full traction situation and you will snap one or both of the center discs in half. With support in all four slots it will spread the pressure, but with only a single pin across only two slots the discs will split in half. And from personal experiance, the company has a reputation of not replacing parts under warranty if they suspect abuse.

But can I use those side gears in a 4pin diff and use a 1510 locker?

Those rings may get in the way.
What sidegears do you need? 22 (front) or 26 (rear) splines?
Where are you located? I may have a set in the garage...

I'm in Australia, shipping would cost too much. Cheers for the offer though.

Well, you know where to come if it all comes down to it.
Good Luck.

Ah, I get it. The one with four pins (sticking out of the sides) is with four spider gears, and the one with two pins is with only two spider gears. The more the hears the better, I guess, to give it more strength.

Bingo!

But when you install a locker, the locker discs replace the spider gears. The discs sit directly over the pins. Think of the pins as the rebar in a cement pad. The more rebar, the stronger the pad.

I'm trying to imagine how the locker will fit, because I am planning on getting one, and my Samurai is 91 year model. So according to you, it has only two pins (One actually). Spidertrax lockers have the option of getting 26 spline side gears, or without them, if yours are ok. So how will the locker discs interface with the stock side gears? And is it possible to drill a couple of holes and install the other two pins?

I'm planning to opt for the one without side gears, because I don't want to change my 22 spline axles. What do you suggest?

The Lockrite style locker you are referring to is sold with or without sidegears. The sidegears they provide make a much harsher 'grab' and thus are not the preferred choice on the trail. Use those on the race track for straight line ( 1/4 mile) style racing.
Use Suzuki sidegears and you will be happier. Less breakage, smoother transitions.
You will be happiest if you can source an early model four pin carrier and then install the lockright with factory sidegears. Trying to modify the 2 pin carrier isn't worth the time or energy.
