DTE Current Differential Model Coverage
We’ve had quite a lot of emails and phone calls lately from customers, dealers and tuners alike, inquiring on what new differential models we are currently building and which we are not. The models not being covered yet are only at a temporary hold and will commence once aftermarket gear sets are available and ready for release. We’re not certain when that will be, but we will let everyone know when we know for certain. We do however, have every other HD internal differential component completed and in production for any model year from 1997-2006.
Models Currently Covered:
1997-2004 C5 Corvette equipped with LS1/LS6 using M6, M12 and A4 transmissions
2 or 3-series cases
2.73, 3.15, 3.42, 3.73, 3.90 and 4.10 ratios available
2005 C6 Corvette equipped with LS2 using M6, M12 and A4 transmissions
2 or 3-series cases
2.73, 3.15, 3.42, 3.73, 3.90 and 4.10 ratios available
2006 C6 Corvette equipped with LS2 using M6 and M12 transmissions
2 or 3-series cases
2.73, 3.15, 3.42, 3.73, 3.90 and 4.10 ratios available
No gear sets available as of yet for the 2006 C6Z or the 2006 C6/LS2 A6 models. The MG 3.42, 3.73 and 3.90 gear ratios are on backorder from MG until Mid-September and if we get them in sooner than that, we'll let everyone know. We hope this clarifies things a bit for some folks.
Best Regards,
DTE

I am ready to pull the trigger on a stage III with micro polish gears, but I cant decided between the 3.73 and the 3.90’s. I have 400 RWHP and I don’t want 1st gear too short. It’s a street car, no racing…yet. Any suggestions

I won't speak for the experts at DTE but I can tell you I have a 3.90 with an MN6 tranny and a little over 500RWHP and the best I can do in first gear to red line is about 35mph. First gear is very short on the 3.90

Figured it would be. Basically with MN6 and 3.90’s you have a lower final drive ratio than the Z06 in first gear. I have been leaning toward 3.73, there is no use in shifting all the time and sitting in first with the wheels spinning.
