These gears have been developed with the Duratec user in mind. The gear tooth profiles are much larger than Ford original spec and are similar to a typical straight cut gear.

The amount of engine torque this gear kit can be used with is about the same as a typical straight cut gearset. The gears are cut to an angle of 25 degrees which means there is more than one tooth driving at any one time.

This is stronger than one at a time as foundin straight cut gearboxes and also 95% quieter. They are also gear shaved after gear cutting to perfect the gear form.

First and second gears are bored out larger than standard which saves weight. In other areas the gear train is also lightened, the benefit of this is enhanced syncro life and a potential faster gear change. First and second gears are also fitted with caged needle roller bearings to reduce friction.

The .82 5th gear pair have an increased helix angle and finer pitch teeth for quieter cruising. Available with long (V6) and short (4 cylinder) input shafts.

We believe these gear ratios are the optimum for most applications where the vehicle is used on the road and for competition use.

The ratios are very similar to those that Ford used for their Rocket helical gear kit during the 70s.

Ford Type 9 5 Speed Gearbox
(Also referred to as a 'Type N' gearbox in some workshop manuals)
Ford’s first RWD 5 speed box was based on the 4 speed Type E and features a cast iron main case with alloy tail housing. This gearbox is the most commonly used for 5 speed conversions on older vehicles, not just for classic Fords but for other classic makes such as MG and Triumph as well as kit cars. A 4wd version of this box was also available and was fitted in early XR4x4 and Granada Mk3 models.

Oil capacity 4wd: 1.25 litres (plus 0.5 litres in transfer box)
