SRT4 quaife...

[The S is Silent]

I'm looking for a LSD to put in my hybrid a555, and was wondering about the Quaife from a SRT4. I know it's a different style diff, but I've heard of it fitting with a spacer for the ring gear and longer bolts.

Does anybody have a link to a site with the specs for the spacer? Does anybody know anything about this? There is one on ebay for cheap...I'm thinking about getting it.

The quaife people are talking about is the neon t-350 quaife, not the one for the t-850 in the srt-4. The regular neon quaife will bolt right into a 520/523 or a hybrid trans. It can also be used in a 404/413/670 with the use of a spacer. What you need to buy for your hybrid 555 is the regular neon diff, or the obx "copy" of the neon quaife.

Yeah, I know there is a difference between them. I thought I read somewhere that the neon guys were putting the SRT diff into the 420a trans with a small amount of fab work.

If I can't do it, I'll spend the $$ for a new OBX or a used quaife.

I heard it also, but never saw any good proof.

By process of elimination I think you could rule that out. We know the t-350 in a regular neon shares the same diff design as the 520/523. We also know that the srt diff shares non of the key dimensions with the 520/523, bearing size, bearing location, axle size are all different. That would seem to make the use of a srt quaife in a t350 unlikely.

Even if you could, most of the used srt quaifes I've seen have been $800+ since the you can't buy them direct from quaife and have to go through chrysler instead. Thats not much of a savings, and then you still have to work to get it in.

In addition to that Chris, the car is discontinued. I dont expect them to stock up on these diffs because they are quaifes.

I have had both Quaifes here T850 and the T350 and the SRT4 Quaife has larger axle shaft splines, larger bearings, a wider spacing for the bearings.

So, in a word, no it won't fit into out transmissions and even if you could/would get it in there you still need to have a set of custom axles made since the passenger side axle on our stuff has the long snout and would need a larger spline and diameter so this would also require a custom right side bearing retainer.

Thanks Cliff.
