DTE "Sportsman Series" C5 Corvette IRS Street/Track Differential

We offer these Sportsman Series rear differential upgrade packages for those that want neck-snapping acceleration that only a performance gear change can deliver! Our "Sportsman Series" lines of Corvette IRS Differentials are built for the Corvette enthusiast who wishes to have a professionally prepared, high performance street/track differential for their C5 automatic or manual Corvette.

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 that build quality... Each DTE Sportsman Series Corvette IRS Street/Track 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! Our in-house production capability enables us to maintain a very tight quality control process. That process guarantees outstanding build quality every time.
