Need help....
I had speedinc install a DTE stage 2 diff on my 01 z car made 416 rwhp ran the car at the track few times with nittos just couldnt hook. I got myself M/T drags 315 's and first try off the line at 3500 launch something broke car would move only for few feet before getting stuck.
Towed the car back to speedinc and diff was sent to DTE to see what they can do about the broken 390 gear. Cost me $600 bucks to replace the gear and some bearing. Anybody else here have this problem with DTE if i would of known before that the diff was that weak i would of kept the stock one on and not paid 1200 for DTE stage 2. Larry told me to go with there stage 4 now since there putting a AA corvette kit on it. (Larry great guy over there at speedinc).

I know plenty of guys running DTE differentials, making 200+ RWHP more than you, and they have dozens of passes at the strip, but then again, they also opted for a stage package made for drag racing, and are typically running a brace or 3 rib case.

The differential model you placed the order for through your DTE Product Dealer and the differential that we received the order for was for a ***STAGE 1*** street differential, NOT a Stage 2 or anything of the like. Why you chose a street differential to go drag racing with (especially with a 6-speed transmission) is beyond our understanding, so if that was your intent from the beginning, than a Stage 1 model was not for you in the first place- as it's not built for drag racing use like our other heavier duty models are...
Often times folks go for the cheapest differential they can possibly get their hands on irregardless of the intended application, which is a foolish decision; because they often buy a unit that is under-rated for their application since they based their decison on price alone and then they are confused on why it failed. We get this all the time....
Furthermore, the only thing that was wrong with the unit was a gear failure and everything else in the unit was like new, so the only parts that required replacement was the ring & pinion itself, NOT the bearings also.....
Lastly, we knew that you had put this unit on the track after we found out you broke it, even though it was the wrong unit you chose for the application and typically, racing parts aren't covered under warranty. ***HOWEVER***, we informed your dealer that we would ***STILL*** cover you to some extent and eat all the labor operations/charges to get you going again if you covered the parts- basically a 50/50 split, even though we didn't have to do anything based on the differential documentation we provided you. We wanted to assist in the situation if we could. Plus, I've squeezed this unit in our already tight schedule by coming in early and staying late yesterday to get this done for you faster than the norm.
Now you still come on this board and bash us anyway for the help we gave you?????? WOW! Maybe a simple phone call first if you had a question, instead of the "attack first and ask questions later" internet behavior??
We're here to help and always have been, but as anyone who knows me personaly, already knows that I'll go the extra mile to help anyone in any way I can if they conduct themselves with us the way they also like to be treated. However, the door will immediately slam shut if we're needlessly attacked online for no good reason...
As always, I appreciate your business, as I do others and I encourage you to **CALL** here first if you have a question about something, rather than what we've seen here today- as that will get you much farther, much quicker. Larry is indeed a good guy over there and he builds a LOT of very high HP cars using our HD racing differentials with outstanding success, so next time, if you have a question- again, please call one of us first and we'll do what we can to help you.
Your differential ships out today back to Larry.
