Upgraded metal gearbox output gears are now available in both standard and oversized gearing!

Machined from billet aluminium these are the perfect replacements for worn plastic gears. They're even better when paired with our roller bearing gears and wider drive belts.

The oversized gear gives approximately an extra 10% top speed and has been tested working on standard C5s. The trade off is reduced hill climbing ability.

We have a limited amount of these available on the website right now. Only 3 of each as we are reserving some for our own and customer projects.
