Custom  Chassis  For  Your  Vintage  Sports  Car

We are excited you have considered using one of our tubular-type chassis under your vehicle. We encourage you to take your time, do all the research you can, and make certain you are choosing the product that is the right fit for you and your project. The following information was put together in order to assist you with this task.

We have created our chassis with the intent to take American sports cars of the 1950’s to the next level of usability, functionality, and performance. This is accomplished in a cost effective and modular package while still maintaining a proper vintage look and feel. Years of research and design have come to fruition in this chassis, providing top-of-the-line performance while maintaining the charm and feel of a vintage sporting car.

While not identical, our chassis maintains the styling and major design features of the Kurtis 500-KK chassis of the 1950s. The updated suspension provides better handling and the use of readily available sprint car torsion bars and shocks. This gives us a level of ride customization that was unavailable at the time of the Kurtis design, allowing our chassis to be scaled to fit any sports car body with relative ease. The Ford nine inch axle housing in the rear will stand up to nearly any vintage power plant, and is the standard equipment in our design. It can, however, be easily swapped out for a different rear end to better fit the purpose of the vehicle being built.

The following is a short list of the chassis components being utilized as well as further options that can be added to  make the chassis fit your needs.

The Basics (all dimensions in inches):
-Chassis will utilize 1.750 OD x .095 wall 1018 alloy steel roll cage tubing

-Anti-roll bars front and rear (finished with vehicle weight totals)

You can contact us with whatever you would like and we will have it priced out and ready when we meet to discuss the project. We are a very capable fabrication shop and will be able to handle most any changes. We look forward to working with you save another piece of exciting American automobile history.
