  If you've ever dreamed of upgrading to a C5 / C6 Corvette Independent Rear or front Suspension,

but you don't have –

  • The expertise to design the system –

  • The equipment to fabricate the parts –

  • The money to hire a reputable shop to do the job –


Then you've come to the right place!

Our Corvette Interface Adapter Kit:

  • Facilitates the installation of a C5 / C6 Corvette IRS into just about anything with four wheels.

  • Takes the guesswork out of the installation and places every suspension mounting point exactly where it was designed to be.

  • Allows the entire IRS system to be installed in fraction of the time that would be required to install even a conventional 4-link or ladder-bar system.

  • Brings the IRS upgrade project well within the realm of many DIY fabricators, and can be accomplished with simple hand tools.

  • Gives the DIY fabricator the sense of accomplishment that can only be realized through a job well done.

  • Is a true bolt-on suspension upgrade, once the rear frame is properly positioned in the car.    

Here's how it works:

The factory C5 or C6 Corvette lower suspension cradle only has mounting points for the lower control arms, because the upper control arms, shocks and even the cradle itself are bolted directly to the Corvette's original unibody frame...





However, with the addition of our Corvette Interface Adapter Kit...

(Shown Below)

...the new assembly instantly becomes a complete top to bottom suspension mounting  platform with additional mounts for the upper control arms, the shocks, the lower cradle, and even the main frame, built right in - making the entire suspension assembly a breeze to install!








Shown below is the Corvette Interface Adapter Kit mounted on a 6" narrowed C5 Cradle, ready to be installed in our Chevy S-10 project truck.






















Above is the final assembly (without the billet aluminum covers)

installed in the S-10, ready for its final wheel alignment.

We at Dobbertin Performance Innovations appreciate your business and highly recommend the addition of a Rear-View Camera with every Corvette Interface Independent Rear Suspension installation. 


This is because the chance of a 'gearhead' lying on the ground behind your car to check it out, exponentially increases with this upgrade – and without the camera, there's a good chance that you might accidentally run over someone.
