The ultimate in competition gearbox kits. Our gear kit is CNC machined to exacting tolerances with 5 dog engagement. The gears are CNC machined from aircraft specification steel and designed to run with very little backlash to eliminate gear tooth wear commonly associated with other dog engagements gear kits on the market. Included in the gear kit are our alloy modular selector forks that are CNC machined from aerospace 7075 alloy which retains the same tensile strength as steel, also supplied are the needle roller bearing for both ends of the laygear along with the 1st / 3rd needle roller bearing and CNC machined 1st and 3rd motion locknuts.

Available super finished for optimum performance and durability. Superfinishing gears using chemically accelerated vibratory finishing brings about a surface textured property that facilitates lubrication. The 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.
