MG Gearbox Conversion Kits

In producing a gearbox that creates a driving experience only hoped for when these cars were first built, Vitesse Global LTD has designed, developed and built arguably the best single upgrade available for both the MGA, the MGB / MGB V8.


At Vitesse Global LTD we have spent untold development hours, making sure our MGA and MGB / MGB V8 gearbox upgrades are everything you want them to be! Due to the thought-through design and careful consideration of our engineering team, these boxes fit exactly in the place of your existing gearbox - no nasty holes, no messing about with an angle grinder, just a perfectly fitting gearbox upgrade. 

We have taken the brilliant Mazda gearbox, used to such great effect in the MX-5 and redesigned a number of components, to ensure this snug and aesthetically sound replacement. All of our gearboxes come with full installation instructions, meaning a keen amateur mechanic should find it no harder to fit one of our MG gearbox upgrades than fitting an original.
