Quaife Engineering is delighted to confirm that it has delivered the first batch of its new heavy duty in-line six speed sequential gearbox, which is rated to over 750 bhp.
Designed to suit the high torque and power handling requirements of the endurance racing market, the new QBE69G incorporates the following key technical features:-
90mm shaft
centres and large gears to maximise strength
Modular six speed gear cluster layout
An integral oil pump for optimised lubrication
A sleek, modern casing design
Semi-automatic paddleshift compatibility
Many choices of gear ratios
Overall weight approximately 45 kilograms

Use of the very latest dog engagement tooth profiles in the 69G has resulted in a six speed sequential unit which allows ultra rapid gear changes and not only offers users a choice of gear lever locations, but also the option to upgrade to a state of the art closed loop, pneumatically operated semi automatic paddle shift system.
The QBE69G gearbox is supplied with a choice of straight cut (spur) or helical gear ratio sets:
