This 5speed Dog Engagement gearbox is a direct replacement for the Ford Type 9 using the same mounting points and hole patterns. This hand built unit incorporates our extensive knowledge to give you unparalleled shift characteristics as well as increased service life. With a 72mm gear centre (instead of 70mm as per standard) and aviation specification material used for all gears to provide added strength and increased service life in these highly stressed areas.
The heart of the gearbox is also the most important. The dog tooth design in our gearbox is paramount to our extremely impressive shift. We use 6 tapered teeth with a tri ground face design which actually pulls the next gear into position which reduces stresses on the teeth and increases the speed and smoothness of shift.
All main shaft gears run on needle roller bearings which eradicates the pitfalls of mounting high speed gears onto a main shaft and gives the gearbox a much slicker operation.
Rigorously tested after assembly the gearbox comes supplied with our alloy lid and breathing system along with our quick shift gear lever to make sure you get the best from the gearbox.
