We offer a selection of new and reconditioned original Caterham 6-speed gearboxes.

These gearboxes are available with the following gear ratios and are equipped with helical gears:

1st gear:  2,690:1
2nd gear: 2,010:1
3rd gear:  1,590:1
4th gear:  1,320:1
5th gear:  1,130:1
6th gear : 1,000:1
Please Note: Not all gearboxes include the necessary mounted sprocket for a mechanical speedometer drive!

Available in "Road" and "Race" versions. The racing version distinguishes itself by offering a stronger shift lever return spring, along with gearbox housing ventilation. If this variant is ordered, the housing ventilation must be connected to a ventilation hose.
Due to its uniball mounted design, the optional reinforced shift lever allows for quicker shifts and a more precise shifting feel. Furthermore, this replacement lever offers the same imperial thread size as found on a series Caterham, making this a simple conversion that even allows for the continued used of an original gear knob.

The propshaft does not need to be changed when replacing a standard 5-speed gearbox with a 6-speed gearbox. However, it is often necessary to change the rear axle ratio.

We are happy to advise you with selecting the optimal ratio, as well as any other questions you may have on converting to a 6-speed gearbox.
