Aston Martin V8 Six-Speed Manual Conversion

Hutson Automotive is proud to distribute the Roadcraft Tremec T56 Magnum conversion kit for classic Aston Martin V8s

Aston Martin V8 Six-Speed Manual Conversion

Hutson Automotive is proud to announce that we will be distributing the Roadcraft Aston Martin V8 Six-Speed Manual Conversion, a complete, fully re-engineered gearbox package built around the Tremec T56 Magnum.

Designed for the V8 Astons of the 1970s and 1980s, from the DBS V8 and AMV8 through to the V8 Vantage, the kit brings six well-spaced ratios, a modern synchromesh change and a relaxed overdrive top gear for long-distance touring. Rated to 700 lb-ft, the T56 Magnum handles a standard V8 with ease, with plenty in reserve for a Hutson high-capacity engine build.

Two versions will be available: automatic to six-speed manual, and five-speed manual to six-speed manual. Everything you need is supplied in the kit, including a CNC-machined bellhousing, billet flywheel, clutch, gear lever and a true mechanical speedo drive, so your original instruments work just as Aston Martin intended.

The first kits are expected in January 2027. Prices and full specifications will be announced shortly, so register your interest now to secure an early allocation.
