Quaife
R.T. Quaife Engineering, Ltd. is a British manufacturer of automotive drivetrain products. It designs and manufactures replacement gearboxes and gear sets, some of which are for four-wheel drive systems.
Quaife's signature product is its line of automatic torque biasing differentials, a form of limited slip differentials that employ helical gears rather than clutch mechanisms that are controlled either mechanically or by computers. These differentials are usually available as aftermarket items, but for some models are specified by automobile manufacturers as OEM equipment.
Quaife has also briefly built complete road cars, with the R4 GTS in 1999 which also competed in the British GT Championship.[1] The company is currently working on the R40.
The company was founded in 1965 by Rod Quaife and now run and owned by Michael Quaife (Technical Director) and his sister Sharon Quaife-Hobbs (Financial Director). Rod's son, Phil Quaife and Sharon's son Adrian Quaife-Hobbs are both professional racing drivers.
Based near Sevenoaks, Kent they have two sites, one in Sevenoaks and the other in Gillingham.
