RESTORATION PARTS

In road racing, you get a lot of practice building rear ends. In thirty years of racing with these differentials, we had only one failure. We sheared the ring gear bolts smooth off at the Detroit Grand Prix. We fed almost 700 HP through stock stub axles and spindles, and they never broke. This is one great piece of equipment.

Your 80-82 Corvette came with an aluminum Dana 44 differential. Nothing is interchangeable with the earlier Eaton diffs. We have been rebuilding 80-96 Corvette Dana 44’s for over 10 years.

There can be a tendency to change everything when the steering feels like an old worn out car. When restored to new, your steering will feel great! Your Corvette front suspension was designed to brake in a straight and stable line. The most widely promoted rack and pinion system doesn't help these cars, as the bump steer is off the charts and it has to be mounted so low to the ground as to make it vulnerable in day to day driving conditions. Note that steering 'feel' can be highly influenced by the condition of the rear trailing arm bushings. When those bushings are worn out, you would swear the problem was in your steering!

When Zora Duntov unveiled the independent rear suspension of the 1963 Corvette, he elevated the American sports car to a world class level. That design remained virtually unchanged for the next 20 years. In the last 25 years, we have learned how to keep this design competitive with the world’s best sports cars.

If you wish to ship your old parts to us, here is what we are currently buying. Remember, freight to us is your responsibility. After receiving, inspecting and (in the case of brake calipers) testing and accepting your parts, we will either credit your credit card or issue you a check. You don't have to buy from us to send in cores - we are always looking for good cores. Please email us for shipping instructions. Prices can fluctuate, so check here first.

We are in the process of adding dozens of additional high performance parts to our interactive website. These parts are all engineered, manufactured and tested over years of racing, and are built and marketed exclusively by Duntov Motor Company. They include everything from bump steer blocks, to rear mounted front caliper mounts, brake ducts, rear mounted alternator mounts, L88 and Grand Sport flares, etc. For now, call or email us for additional information.
