MED DOG GEAR KIT
The ultimate in competition gearbox kits for the Mini, used by race winners and champions worldwide. Our gear kit is CNC machined to exacting tolerances with a five-dog engagement.
The gears are machined from vacuum arc remelted S156 steel and are then Cryogenic treated for ultimate performance and durability. These gears are designed to run with very little backlash, to eliminate gear tooth wear commonly associated with other dog-engagements gear kits on the market.
The modular selector forks are also CNC machined from aerospace 7075 aluminium, which retains the same tensile strength as steel. The kits are also supplied with the needle roller bearing for both ends of the lay-gear, along with the first/third needle roller bearing and specially machined first and third motion lock nuts.
Also available with "Superfinish" option for optimum performance and durability. Superfinished gears have a chemically-accelerated vibratory finishing that provides a surface-textured property to promote lubrication.
Superfinished gears will experience reduced friction, lower operating temperature, less wear, better scuffing resistance, and better contact fatigue resistance, all of which contributes to a better running transmission.

The ultimate competition gear kit, as used by champions in Mini Miglia, Mini Se7en, historic, sprint, hill climb and rally events worldwide.
Also used by most premier engine builders with ultimate reliability.
