[file] To all,
My good friend has a small welding fetish and has created Nicks Stiff Diffs.

How are you liking yours Steve? Look forward to seeing how it works at Nationals.

It is awesome.
Gotta be careful in the paddock with u turns so you don’t break off an axle.
way better than my LSD.
I don’t sense any push or either. The car seems to track out 10 times better now.

Hi Steve,
are you comparing welded to a tired LSD or a good one?
Do you have a sense of how tight of a radius turn it starts becoming a disadvantage?
cheers,
bruce

Any idea exactly what else he does to the diff besides welding?? New side seals, cover gasket, etc??

$200 sounds pretty steep to me, but I’ve got a welder and do it myself- so I might be predjudiced… :wink:

Bruce the lsd was old not tired.
I have only experinced better track out at Infineon.

Bret,
He offers only experience and knowledge of what a 400 plus hp rock crawler can do to a DANA 40. The guy is all about the process and why and what happened before under severe torque. I promise it aint no back yard tack weld, the guy knows what he is doing.

I hear ya- BUT, it’s not that difficult to simply weld up the spider gears in an E30 diff, assuming that’s what he’s doing. If he’s doing something else for the $$$, it’d be interesting to hear about it.

Don’t take this the wrong way, having done a couple of these, I can appreciate what’s involved and $200 is not unreasonable.

Are these tigged or mig welded. I was going to tig one have but i’m a little timid about the amount of heat needed to melt the hardened steel on the spider gears.

I use a Mig welder. I can’t claim to be an expert- since I’ve done 2 of them- but so far so good.

I don’t think the hardness of the gears is a factor when it comes to melting them- I’ve never had a problem with it. You really just need to stick the gears together and jam up the space in between teeth with metal from the welder. I have a pretty big 220v mig welder though- so you might have some trouble with a small 110v welder.

Like I said before the thought has gone in to this.
Without given up the secrets I say "this ain’t no back yard tack weld".
Nick has a jig and templates made up for the application.
It includes more than melting the spider gears together which is at least the most obvious process.
He has seen explosing that we don’t need to see.
It is with that knowledge that I back his welding.
The number is on the sticker that I will be running at the nationals so give him a call.
