DTE Powertrain has pioneered and perfected nearly every major durability/performance advancement of the aftermarket C5 Corvette IRS Differential since the beginning of the decade. Our innovative driveline products have repeatedly set the bar high to where our competition can only compare themselves to and our depth of in-house engineering/manufacturing capability allow us to consistently stay ahead of our competition time-and-time again.

Our driveline products are expertly engineered, thoroughly tested and are produced of our own exclusive design that have been validated in the field with track-proven results from our various customers globally. Additionally, our products are actually our own design…not just simply name re-labeled parts coming from other manufacturers that are seen from other builders.

DTE application-built differentials are blueprinted in-house using premium components with quality, precision and durability in mind as an engineering target first- not simply built cheaply with questionable parts, just for a low-ball price that are also seen from other builders. In short, if you're looking for a "cheap" differential that's thrown together using "cheap" parts that are pirated copies of our original design, then assembled with short-cut build techniques- than DTE Powertrain is not for you...

We feel you deserve nothing less then the best we have to offer, coming from the industry leading professionals for your high performance C5 Corvette! Give DTE a call today when you're ready to upgrade your Corvette’s drivetrain with a no compromise approach in build quality and leave your competition broken on the starting line!

***Any complete, rebuildable differential with any ratio redeemable as core!***

1997-2004 Corvette

Differential Power Ratings:
We do not attach a power rating to any of our heavy duty driveline components or differentials for a few very specific reasons. Typically the horsepower of an engine is *NOT* what damages drivetrain parts, torque and application does however; so to put an inaccurate rating on a driveline component is foolish for the builder and misleading to the customer- therefore we don't do that in any capacity. Additionally, "rating" any sort of driveline component with any sort of power ratings is typically a marketing strategy only meant to sell parts, without regard to giving the customer what they really need based on how they drive the car and what the intended usage is for that car. Lastly, when making the decision to purchase a differential, one needs to take into consideration how much power the car currently has, how much it will have, the intended usage for the car, if the car will be taken to the track...ever, if the car has wider/stickier compound tires compared to stock and if the driveline will use a differential strut or not. Plan to experience wheel hop, (which we *HIGHLY* discourage, because most Corvette's do to some extent if *ANY* of the driveline suspension components are left stock, (i.e. control arm bushings, shocks and alignment) so add strengthening options accordingly to provide a cushion for that. Build the strongest driveline you possibly can within your budget and drive the car accordingly based on the options you chose. One can *NEVER* have too much driveline strength for any vehicle platform.
 
IMPORTANT NOTICE!
 DTE has ALWAYS been the LEADER and PIONEERS in producing innovative, high performance, high strength C5 /C6 Corvette driveline products for over 4 years…long before anyone else was doing it or felt the need to. NO other Corvette differential builder offers the same level of component preparation, build quality and professional engineering into their driveline products as DTE does.…...period! 

Don't be fooled by other "cheaply built" differentials that others offer that don't include the same level of attention to build quality, professional engineering and component detail that DTE always offers as "standard" equipment; such as including cryogenically treated gears sets, complete assembly deburring, etc.  We are also the ONLY Corvette IRS differential builder to successfully convert the 2-series differentials to accept the 3.15, 3.42, 3.73, 3.90 , 4.10 ratio's without sacrificing durability of any kind! Many of them are in continued use on the drag strip to date with outstanding success!

Our competition consistently trails DTE in high performance, design engineering concepts for the Getrag Differential. They often copy our high performance differential components and blatantly label it as "their own design" or "concept" directly off the back of all of our R&D efforts. Some of our own product description text found on our website has even been found to be shamelessly cut-&-pasted directly onto our competition's website even though they are not authorized DTE product dealers!

The bottom line is~ Our Corvette driveline products may be imitated by our competition for themselves, but they will NEVER be duplicated to our precision engineering and quality. DTE is and will remain, the leader in creating innovative, high performance, HD Getrag Differentials and components, as we are relentless in our quest for the "perfect" product design. When it comes to driveline component quality and build services, you certainly get what you pay for!!!
