***Exclusively from Downforce Motorsports!!!***

From the original blueprints and castings to the exact locations of the rivets, the Riley/ Kar-Kraft MkIV is a true continuation of the legendary MkIV from start to finish!! 

The Riley engineering team has already spent countless hours taking authentic paper documents and drawings, original castings, fixtures and molds and converting them into current design software to aid in refining the build process. When it comes to insuring the authenticity of the MkIV, the continuation MkIV is a result of very close attention to detail in both design and the materials used.
With the exception of improvements in alloys and safety, the team at Riley has taken considerable time reviewing each document, drawing, component as well as interviewing those involved with the original MkIV project. All of the components will be made using the original designs and authentic production methods, resulting in truly legendary piece of history!

The original MkIV, known as the “J-Car”, was the first race car produced with an aluminum honeycomb chassis combined with a steel roll-cage with the goal of creating a lighter, yet stronger car. This type of design, born from the aerospace industry, became the basis for motorsports chassis construction until carbon-fiber tubs emerged many years later. Kar-Kraft, an independent Michigan-based race constructor and automotive prototype company, was commissioned by Ford to develop the GT40 MkII and then subsequently build and develop the MkIV. The MkIV raced at Le Mans and pick up where the winning MkII left off, featuring improved suspension geometry, engine development and aerodynamics with a lighter chassis, scoring the overall victory in 1967.

The MkIV ran in only two events in 1967, winning them both. The first success came early in the year as Mario Andretti and Bruce McLaren won in impressive fashion at the 12 Hours of Sebring. Only a few months later, four more chassis were entered in the 24 Hours of Le Mans with Dan Gurney and AJ Foyt sharing the victory. The 1967 24 Hours of Le Mans still remains the only all-American victory in its history (drivers, chassis, engine, tires and team). In all, twelve MkIV chassis were built, with an additional seven continuation cars constructed by Kar-Kraft over the years since.

Riley is proud to be able to continue the manufacturing of the truly legendary MkIV racecar, taking on the Kar-Kraft assets including tooling, fixtures, molds and engineering drawings, to produce the authentic period correct MkIV again for those looking to own a part of history.
