Default source for rear differential

I'm looking for a source to purchase a 3.73 or 3.9 rear differential to be used with sc 650 rw hp application.

Dynotech will not be able to provide until this fall(out of stock).

Any suggestions on who might carry? Thanks.

Check out a post by BoostedBlkZ06, I believe he is selling a 3.90 diff or gears, maybe it will help you out.

Motive Gear is on a National backorder of 3-series 3.90, 3.42 and 3.73 gear ratio sets until the Fall, according to MG. We do have quite a number of all of these ratios in stock, but they have been spoken for in advance from our other customers, installing tuners, etc.~ before we knew of the shortages. MG tells us that they *may* have a shipment sooner than that, (July) but that is not confirmed. They get shortages like this every-single-year to some extent, so it's nothing new...


Regards,
DTE

Sounds to me from DTE's response that possibly one of the installing tuners that buys from DTE might have what you're looking for. I wonder if places like Lingenfelter, A&A, L.A.P.D., West Coast Corvettes, etc. might have one even if DTE can't sell you one at this time.

GM actually sells a brand-new complete 3.73 carrier. I have called Shawn @ the LAPD and he once said he could get it. But it was pricey though...
