Quaife dog engagement gearkits are designed for drivers seeking a high strength geartrain that offers rapid gear selection. These gearkits completely dispense with the original synchromesh engagement mechanism, instead using a motorcycle-style 'dog-tooth' arrangement where each gear meshes to the next by a series of hard wearing precision machined teeth 'or 'dogs.'

These 'dogs' interlock with each other to provide a stronger, more positive gearshift than is physically possible using a synchromesh arrangement, which can easily be 'beaten' during a fast shift and is ultimately likely to fail if continually abused. In 'H-pattern' format, the real limiting factor on gearshift speed with a Quaife dog engagement gearkit is driver ability.

The gearkit also features 'straight-cut' (or 'spur') tooth profiles where each tooth is machined at angle straight across the gear, enabling torque loads to be transmitted at right angles to the main gearbox bearings. This has the potential to increase gearbox durability and reduces parasitic transmission power losses to a minimum, meaning more engine power is delivered to the car's driven wheels.

This Ford Bullet (2000E) 4-speed dog engagement Quaife gearkit is designed as a direct replacement for the standard Bullet gearkit. This close ratio gear kit provides ratios which are better suited to competition use, with dog engagement to replace the synchromesh.

  • Dog engagement for faster gear change.
  • Straight cut, close ratio gears.
  • Needle roller bearings support free running gears.
  • Includes Quaife mainshaft.
  • Larger, Rocket sized spigot bearing.
Gear ratios available:
2.250/1.495/1.168/1:1
2.500/1.660/1.220/1:1
