Quaife designed the QBE62G to provide a modern, uprated, robust, direct replacement transmission for the ZF DS-25/2 gearbox as used in the Ford GT40, DeTomaso Pantera, BMW M1 and many other mid-engined supercars.
The fitment, major dimensions, gearchange location and shift system used on the Quaife QBE62G replicate the ZF DS-25/2 gearbox, while the five speed ‘H-pattern’ layout and distinctive ‘dog-leg’ first gear location are also retained to ensure authenticity.
Developed in conjunction with a British-based replica manufacturer, Quaife has ensured that the unit’s length allows for easy installation into Ford GT40 type cars, but QBE62G is also suitable for numerous mid-engine replica and kit car applications.
Key engineering details include the use of 85mm shaft centres and an ultra-reliable hypoid crownwheel and pinion, which enables the QBE62G transaxle to handle a maximum recommended 500bhp. Helical gears are included with a synchromesh gear selection, minimising gear noise and ensuring everyday usability. Designed for either rod or cable-operated gearchange mechanisms, while a Quaife oil pump and clutch lever assembly are available as optional extras.
