We offer this must-have rear differential upgrade for those that want neck-snapping acceleration that only a performance gear change can deliver! Our Sport Series line of Corvette IRS Street Differentials are built for the Corvette enthusiast that wishes to have a professionally prepared, high performance street differential for their base C6 manual Corvette, without having to go overkill with the purchase of our very
heavy duty racing differentials we also offer.
Unlike O.E. GM differentials that are limited to stock gear ratios and slapped-together on a production line where assembly speed is more important than build quality - Each DTE Sport Series Corvette IRS Street Differential is available in a wide selection of gear ratios to suit your specific application and each unit is entirely prepared, hand assembled and blueprinted right here in the USA! This in-house production capacity enables us to maintain a very tight, 100% quality control process that guarantees outstanding build quality over the completed product every time, so you receive a finished differential that performs as you expect.
For nearly a decade, DTE Powertrain Inc. has continually been referred to by our customers, as the Gold Standard in high performance Corvette drivetrain, where our products have been in more race winning applications competing in Drag/Auto-x/Road Racing and setting more performance records than any of our competitors combined. Achieving a higher level of product engineering DOES make a resounding difference in the exceptional build quality and track proven durability of our driveline products, where you will simply NOT find a better equipped, professionally built, high performance Corvette differential anywhere else for your money period!! Give us a call when you're ready to unlock the true acceleration capability of your high performance C6 Corvette, with specialty drivetrain products coming from the pioneering leaders of innovation in the aftermarket Corvette IRS driveline industry!!

Transmission Power Capacity Ratings:
We do not attach a numerical power rating to any of our differentials, transmissions or drivetrain components for a few very specific reasons. Typically the horsepower output of an engine alone is *NOT* what damages drivetrain parts, but rather a combination of power, torque and the environment the component is used for in that application is however. Therefore, it's not only foolish for the builder/manufacturer of the driveline product to do such a thing, but its also directly misleading to the customer, since this is not enough information alone to base an accurate decision on what product the customer needs to be the most cost effective and durable selection for their given application.
Additionally, rating any sort of driveline component without any credible data to back up that fictitious claim as our competition often does is typically a marketing strategy only meant to sell parts, without giving proper regard to the customer on what they really need based on how they drive the car and what the intended usage is for that vehicle.
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 of the car, if the car will be taken to the track, if the car has wider/stickier compound tires compared to stock and if the driveline will use a differential strut or not.
Plan for wheel hop, (which we *HIGHLY* discourage) because most street Corvette's do this to some degree if *ANY* of the driveline suspension components are left stock. (i.e. control arm bushings, shocks, alignment, tires, etc.) Always add additional strengthening options accordingly to provide a cushion for that also.
In other words~ build the strongest driveline you possibly can within your financial boundaries and then drive the car accordingly based on the options you chose. One can *NEVER* have too much driveline strength for any vehicle platform and choosing a differential based entirely on a cheap price that is under-rated for your application, will only cost you far more money in the long run to fix it again the second time after you had the chance to do it right from the beginning.
