Synchro Gear Kits

Homologated and custom gear sets.


Close ratio, straight cut gears make the best use of the power produced by your engine. Gearboxes are often overlooked. There are about 3 homologated gear sets for the 116/75 range and we stock the most common ratio set allowed across the whole range. Available in standard synchro or Dog engagement, all gears are very high quality and heat treated. They are needle roller throughout and the kit includes main gears 1-5, new lay shaft and gears 1-5+R and in the case of the dog box it includes the sliding dog hubs. We can offer a build service or even complete boxes with LSD. Price given is for the Synchro kit,
