Quaife motorsport gearboxes are proven globally to deliver robust transmission excellence, season after season. Freed from the compromises of everyday road use, Quaife's range of advanced, heavy duty replacement motorsport gearboxes incorporate innovative technology to deliver real performance benefits.
Available for a variety of popular vehicle installations and drivetrain formats, Quaife motorsport gearboxes use high strength, contemporary tooth form technology and gear engagement design combined with wide shaft centre layouts. This enables the transmission of higher torque loadings than road transmissions and faster ratio selection, while users can exploit a choice of close ratio gear sets and final drive ratios (where available) to further optimise performance.
Universal 6-Speed In-Line Sequential Gearbox with Helical Gears - Direct / Overdrive
The Quaife QBE60G heavy duty In-line 6-speed RWD Sequential Gearbox is a direct replacement upgrade for the popular Ford Type 9 transmission and since its launch in 2008 has become the market leader in this sector.
A high strength 80mm shaft centre design with all alloy casings enables QBE60G to handle up to 375bhp, yet it can be installed into a Mk1 / Mk2 Ford Escort or
Caterham 7 without transmission tunnel modifications.
QBE60G features a modular gear cluster, allowing easier interchangeability of gear ratios and fewer moving parts, while a drum type sequential gearchange system is allied to an open face dog design on both gear and drive disc. This produces a positive, ultra-fast gearshift – an optional Quaife approved ‘intelligent’ semi-automatic paddle shift is also available.
Free running gears are supported by needle roller bearings to ensure a robust geartrain, while a choice of ratios and numerous gear lever position options allows customers a wide scope for optimising QBE60G to suit their individual requirements. Weighing just 38 kilos, QBE60G is ideal for rally and race use in Mk1 and Mk2 Ford Escort, Ford Sierra, Caterham, Westfield and numerous rear wheel drive kit cars.
Both helical and straight-cut (spur) gears are available on the QBE60G. The former enables the QBE60G to appeal to ‘fast road’ customers where gear noise is a critical issue.
Key features of the QBE60G heavy duty six-speed
sequential gearbox include:-
• Direct replacement for Ford Type 9 gearbox
• Ultra-fast sequential gearchanges
• Numerous input shaft and gear lever position options
• Weight approximately 38kg
• Direct drive, overdrive or double overdrive
• Over 1000 in use worldwide

Quaife ATB Differentials
A direct replacement for the standard open differential, the Quaife ATB differential transforms your car’s performance.
Unlike a conventional plate-style limited slip differential, the Quaife ATB differential relies on gears rather than clutch plates for its operation. That means it is much smoother in operation.
The ATB differential never locks harshly with a set pre-load of wheel slip across the driven axle, like a conventional LSD. Rather, it automatically biases the torque away from the spinning wheel across the axle, to a constantly varying degree, and never locks.
The ATB differential has many benefits over a standard open differential, including maximising traction and minimizing wheelspin, eliminating torque steer and snatching in front wheel drive cars compared to conventional LSD units, and a maintenance-free design, which retains the standard oil lubrication.
The Quaife ATB differential is proven in circuit and drag racing, rallying and road use, is produced from Corus steel billets, and is CAD designed and CNC machined, all whilst maintaining ISO 9001 standards.
With over 370 applications, the Quaife ATB differential is second to none. Accept no imitations!
Quaife ATB differentials are used by Ford, General Motors and Daimler-Chrysler as original equipment.
The Quaife ATB differential is also subject to a lifetime warranty (subject to terms and conditions).
