We have a significant amount of experience building gearboxes and parts for road, race or rally Austin Healeys. Our range includes parts for side change and centre change gearboxes. We have invested heavily in CAD/CAM design and manufacturing alowing us to increase the range of products we offer. With the recent introduction of our centre change gearboxes cases we have now completed the puzzle to allow us to build brand new gearboxes. In addition we also offer a range of gearboxes from stock for outright purchase, no exchange required. Different gearsets are available including: helical and straight-cut gears, TULIP and SEBRING ratios.

As well as parts we can also offer customers a rebuild service. Why not let the Healey experts build your gearbox?

CNC machined using our own CAD drawings.
