Can I fit the kit myself? 

The short answer is yes. If you are a confident mechanic, capable of removing and installing a standard Morgan gearbox you will have no trouble in fitting one of our kits, as everything has been specifically designed to match your Morgan - no bodges here! 

If, however, your mechanical skill stops short of gearbox installation, we’ve got you covered. We offer an in-house fitting service at our HQ in Leicestershire, UK, where the team that designed and build our Morgan replacement gearboxes, will fit your box for you. 


If Leicester seems like a bit of a stretch of a journey, we can ship your gearbox directly to a mechanic of your choosing and deal directly with them, should they have any questions regarding best practice during the install.

Unsure if you could fit our Morgan gearbox yourself? Take a look at our installation instructions.


Want to lighten the load?  

The all-alloy case on our Morgan replacement gearboxes means significant weight savings can be achieved with this kit- up to 23kg compared to the R380!

Our gearbox is the ideal replacement for your Morgan gearbox. 

Gear Ratio - Mazda Transmission
