Jaguar XJ Quaife Differential units – Jaguar XJ Limited Slip Differential
The Jaguar XJ QUAIFE differential will prevent loss of drive and traction that occurs with a standard Jaguar XJ differential wheel slips.
Whilst requiring some torque in the slipping wheel, the Jaguar XJ limited-slip differential QUAIFE Diff unit is progressive in action but does not lock completely – controlled power is transmitted through the limited slip Jaguar XJ differential to all the driving wheels.
Installation is identical to the normal Jaguar XK differential with bearing pre-loads and pinion mesh being restored to the original Mini differential manufacturers’ settings. Servicing of the Quaife Jaguar XJ differential unit is simple as all gear pinions are free fitting and normal final drive lubrication oils are retained.
Benefits of the Quaife Jaguar XJ differential
• All Quaife Jaguar XJ differentials come with a Life Time Warranty
• The Quaife Jaguar XJ differential maximises traction and minimizes wheel spin
• Proven in drag and circuit racing, rallying and road use
• Eliminates torque steer and snatching in fwd cars compared to conventional Jaguar XJ LSD
• Quaife Jaguar XJ differentials are a maintenance-free design and retains standard axle lubrication
• The Quaife Jaguar XJ differential is produced from British Steel billets throughout
• CAD designed and CNC machined then inspected to ISO 9001 standards
• Massive range available for most Mini’s and many other vehicles Quaife Jaguar XJ differential –
More traction, more speed As engine power outputs increase even further, the ability to use the extra power and performance becomes even more important. Wheelspin may look great but in reality, is it a loss of traction and control, a waste of time uses fuel and tyres whilst going nowhere!
Whether driving on the road, track day circuit, rally stage or drag strip – you need a Quaife Jaguar XJ differential to give you control and usable power. Fortunately, QUAIFE’s patented Automatic Torque Biasing (ATB) Helical Mini LSD differential is an effective, well-proven, low-cost solution. As a direct replacement for the standard, factory ‘open’ Jaguar XJ differential, QUAIFE’s ATB Helical Jaguar XJ LSD unit can transform the performance of your Mini.
Unlike conventional plate-style Jaguar XK limited-slip units, QUAIFE’s ATB Helical Jaguar XJ LSD unit relies on gears, rather than clutch plates for its operation.
That means it is much smoother in operation because, unlike a conventional plate-style Jaguar XJ LSD, it never locks harshly with a set pre-load of wheel slip across the driven axle. Rather, it automatically biases the torque away from the spinning wheel across the axle, to a constantly varying degree and never locks.
To the driver, the results are significant performance improvements; – superior, controllable traction without the harsh steering wheel snatch or torque steer that have long been associated with performance differentials.
These traction benefits can also be utilised in rear-wheel drive vehicles, while Jaguar XJ QUAIFE ATB Helical Jaguar XK LSD units offer significant traction advantages fitted to the front or Rear-wheel drive cars.
The Quaife Jaguar XJ differential units are designed using the latest CAD techniques and are CNC machined to ultra-tight tolerances from the very best CORUS steel billets.
The completed Quaife Jaguar XK differential units are then subject to rigorous in-house inspection on a tri-coordinate measuring machine before being dispatched to the customer. Such quality means that unlike a conventional plate-style Jaguar XK LSD the Quaife Jaguar XJ differential unit requires no special maintenance or rebuilds, is long-lasting and it retains the standard method of lubrication, making for an easy, pain-free upgrade.
Proven in rallying, racing and on the road, the Quaife Jaguar XJ differential offers safe, reliable, winning performance. Paramount can supply Quaife differentials for almost all Jaguar XJ models, if you don’t see what you are looking for please email us
