how do I put a supra posi in a truck diff?

I would LOVE to have one of those LSD's for my daily driver 4Runner... The one I drive 80 miles each day to & front work... I can't think of anything more perfect for additional winter time traction and light wheelin' while still being transparent on the road <IMG SRC="smilies/smile.gif" border="0">
Yep, I definately agree (it doesn't hurt anymore <IMG SRC="smilies/biggrin.gif" border="0"> ). But I think I'm going to wait and put an e-locker in my 4Runner since it will be seeing moderate off-road use. I sure wish we could get the Tru-Trac that has an e-locker built in, but they aren't making them for Toyotas yet <IMG SRC="smilies/frown.gif" border="0">
I've had the opposite experience with my rear locker in the snow. I think it's great! Not dangerous at all and I can go farther in 2wd. Only time it gets a little hairy is on ice but it's no big deal to me, the exta traction off-road is more than worth it. <IMG SRC="smilies/smokin.gif" border="0"> <IMG SRC="smilies/usa.gif" border="0">

Pretty easy to put it in. Ring and pinion are exactly the same, so you can swap over your gears. Here is the one problem though, you will not have enough room for the adjuster on one side, so you have to use one bearing race from the supra, and the other from the truck. They are the same, just one of them use a thicker outer section on the race. Compare the two and you will see. I ran one for about a month, until I blew my gears because of too much power.
Can you just throw the Supra carrier into a truck housing with the truck ring and pinion, and use the same races that are in the truck diff? Probably needs to be a 6cly. diff. though? So, then just put the truck ring and pinion in the Supra Carrier? I was thinking this would be good up front untill I can afford ARB. Does the L/S only come in the turbo models, and what other years? Gibby, How much did pay for yours? (Pic-n-Pull Yard?) <IMG SRC="smilies/biggrin.gif" border="0">

I got mine from a supra owner for $100. The 86.5 and newer turbo is the one to look for. Pre 86.5 fits ifs front. Some cressidas also may work. As for the install, Gearman told me a couple of years ago that if you install it in the v6 diff it weakens it. maybe he will jump in now and clarify it as I don't remember everything he said. Gibby

You have to use a combination of bearings and races from both, or go to bearing house, with mesurements that you need, and get some new bearings that will work. It will only work in the V6 carrier.
Gearman is right, it does weaken it a little bit, but no the housing, the right adjuster, whiched doesn't see much of the force. The left adjuster gets most of it. On the right adjuster you don't get as many threads to bite into, so the adjuster could evenutally weaken and pop out. If done right, I don't see this happening. If you were to get a skinnier bearing for the right side, you could put the ajuster in more.
I ran the supra LSD in my truck running 250hp and a racing clutch from a supra. I ended up ripping the gears apart, but the carrier and housing stayed intact.
I believe Gearman has seen them fail, but then agian, how was it set up?. Depending on gears that you have, it might make a difference. If you don't think you have enough threads on the adjuster, than don't do it.
