    Can I fit the kit myself?
    In short, yes. If you are confident removing and installing a standard Morgan gearbox you will have no trouble fitting one of our kits, as everything has been specifically designed to match your vehicle.

    However, if your mechanical skill stops short of gearbox installation, we’ve got you covered! We fit our gearboxes at our HQ in Leicestershire and can have your pride and joy in and out in a few days. The gearbox will be fitted and checked by the very people who designed it, too. If a trip to Leicestershire is out of the question we will happily send your gearbox directly to your chosen mechanic and work directly with them, should they have any issues fitting. 


    Want to lighten the load? 

    Our full alloy case means significant weight savings can be achieved with this kit- up to 23kg compared to the R380!


    The perfect ratio: 

    Our gearboxes, as fitted to some current Morgans, are perfect for the vehicle, offering a great delivery of power throughout the rev' range and the box.
