Having pioneered the sequential gearshift in the late 1980’s, Quaife has proactively continued to develop and refine its sequential gearbox technology to improve reliability and to adopt integrated electronic paddleshift systems. Quaife is reactive to external requirements and is constantly evolving its gearbox range to suit market demands. Numerous bellhousings for popular engines are available from stock to enable the easy installation of Quaife’s in-line transmission range into a variety of vehicles, as is a range of accessories, including a choice of gear levers to suit individual requirements. Irrespective of selection method, Quaife’s close-ratio gears reduce the rev drops between gearshifts enabling even highly tuned engines to stay operating in their optimum power-band at all times, while the choice of gear ratios and final drives (where available) allows users to fine tune gearing to suit their particular requirements. Dog engagement enables rapid ratio selection without the performance or wear compromises of the synchromesh mechanism and is largely intended for motorsport use, whereas the helical variants of Quaife gearboxes are equally at home in a road environment. Quaife’s motorsport gearbox range includes complete replacement in-line, transaxle and four-wheel drive transmissions, offering five, six and seven-speeds depending on application, with a choice of synchromesh or dog engagement and helical or straight cut (spur) gears.
Designed using the latest FEA 3D software, precision engineered using state of the art CNC machinery, assembled by skilled and experienced technicians, tested, refined and perfected using all of the firm’s considerable drivetrain expertise, Quaife motorsport gearboxes offer unrivalled reliability, performance and value for money for racing, rallying, drag, trackday and fast road use.
