Quaife begins deliveries of the New Heavy Duty QBE69G six speed sequential in-line Gearbox.

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

Choice of input shafts available

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:
Gears: 1st 2nd 3rd 4th 5th 6th

Spur (1:1) 2.435 1.858 1.494 1.268 1.116 1.000

Bellhousing options including Dodge Viper and Sierra Cosworth YBT pattern are already available and, in addition, use of an specially designed adaptor plate ensures that the QBE69G is compatible with fitments already offered for Quaife’s smaller QBE60G unit, including the Ford Duratec and Nissan 350Z.

Various input shaft options are also available from Quaife on request to suit customer requirements.

Quaife’s popular digital gear position indicator is also directly compatible with the new 69G and is available as an optional extra, ex-stock.

Forward orders are now being taken for the Quaife QBE69G unit, which is competitively priced at £6595.00 excluding VAT where applicable.
