Will it work in the A413 also? If so, I'll take it...

[135sohc]

Yes it will.

I do not know for sure. Craig is pretty smart with these cars, and if he says it fits I would trust his word.

[ShelGame]

Thanks! I'll take it. Send me your PayPal info and I'll send it over...

[lengel]

Sold!

just run extra magnets in the trans pan

How does that LSD work??

[moparzrule]

It goes between the spider gears and pushes out on them. Simple but affective. It's a good street LSD, not so much drag race.

I disagree. I would not run it on the street, at all.

This is not made by Phantom Grip.

Less than 5000 miles.

So thats not a PG unit? If not what was it and why should it be compared to a PG unit? Was this yours?

Perhaps that one was not installed correctly....perhaps the spider gears were too worn out and should have been milled first.....perhaps the carrier bearings were worn out causing a bad load on the unit....perhaps that unit had way too stiff of springs for street use.

There's way to many factors to show one mishap and say it's no good to run on the street. Thats like melting a wiseco piston, change your tune and install JE's, and then recommend to not to run wiseco's....the problem wasn't the piston, it was the tune. The problem there is not the PG unit, it's something else. I know people that have had a PG unit in for 50k miles.

Or the design of this type of block LSD is inherently bad from the start. Think about it, every time both wheels are not spinning at the same speed, your are grinding metal against metal.

The unit in the picture was bought from Omni Potent, along with lathed spider gears prepared by them.

I will never used another "block" LSD in my car no matter the make, due to their design.

[moparzrule]

And everytime a piston goes up and down a cylinder it's metal against metal. The oil is there to lube it. Not sure what to say, but the worst I've seen a PG unit do is just stop working well after 20-30k miles. I would still contend that something else was wrong, or they use inferior metal to make the block. From the look of it, that appears to be the case. You can see clearly on this PG unit for sale, which is used, it has virtually no wear on it. If yours did that in 5k miles, I'm sure he had more than 50 miles on this PG unit, so it would have already been showing significant wear. You can only see slight signs of rubbing, but certainly no actual indentation of wearing down.

[tryingbe]

Piston rings don't have ~700 lbs of force pushing behind it against the walls like these block LSD do. Oil works to lube the pistons/wall while oil works AGAINST block LSD as block LSD need to have metal grinding each other for it to work correctly.

I'm done talking about these inferior products. Shelgame races in classes so he have to meet certain specs, but for others, the OBX LSD will work much better.

I need an OBX, too.

This is for the new race car which currently has a welded diff (which isn't legal or safe) and breaks axles.

The PG type may not be perfect, but its better than that...

[knownenemy]

Interesting thread; although a for sale thread,
the information should maybe be moved to a FAQ about the block LSDs.

I had considered one for my hybrid a520/a555,
but the OBX is surely the more reliable way to go; I've read.
(also twice the price. lol)

Rob, if you happen to disassemble the diff. I have some clutches left over from an old posi project. They are fibre style that fit between the axle gear and carrier, to be used in place of the factory shim. I cant remember the thickness of the top of my head but either .060" or .090" sounds right. They are totally ATF compatible and will not contaminate your ATF as they wear. I still have a few side gears that were machined to accommodate the extra thickness of the clutch. There are many machining variances with our diffs. so some will accept the shim as is and some require machined side gears. I have had excellent results with these diffs. even with the Ford 7.5" spring and my own sorta "P.G". style blocker. The price of the OBX makes anything else obsolete!!

Thanks
Randy

Its on my bench now.

I'd love to have a set of those clutches. Even 2 or 3 sets if you have them. My car will need a fresh trans eventually, too. I was planning for an OBX, but if the clutches help this diff out, I'd be willing to stick with it.

Check out my LeBaron project log...

[GLHS60]

Rob, if you P.M. your mailing address I'll send you a couple of clutches to experiment with.
If you want, include your phone # and I'll give you a call and share what I can as I'm a 1 finger typer .

Thanks
Randy
