Quaife ATB Differential - Honda EG5 (D16Z6, D15B engine etc) S20 gearbox

Product Information

The Quaife Limited Slip Differential will totally transform your car. It is a direct replacement for the original equipment ‘open differential’ and provides superior traction which is not available with an original open differential fitted.

Unlike a conventional uprated plate-style limited slip differential, the Quaife LSD relies on gears rather than clutch plates for its operation. That means it is much smoother in operation and is a “fit and forget” modification, as opposed to a plate diff which will require regular removal of the gearbox to maintain.


How the STOCK HONDA open differential works:

When driving in a straight line an open differential provides drive to ONLY ONE WHEEL. When turning, it provides drive TO THE INSIDE WHEEL ONLY, this is the case even if you are experiencing wheel-spin. When turning, driving just the inside wheel creates a situation called ‘under-steer’, this means that in a left hand turn, due to a loss of traction, the car drifts out to the right. This is a highly undesirable situation and detracts greatly from the performance available. This is the case even if the car is standard (i.e. unmodified). The problem is even greater on a car with power upgrades.

How the quaife limited slip differential works:

In a straight line the Quaife Limited Slip Differential will drive both wheels, therefore immediately the traction is improved by 100% as compared to factory fitted ‘open differentials’ as described above. In a corner the automatic torque biasing action of the Quaife LSD means that power can be distributed to either/both wheels and is given to the wheel that has the most traction. This automatic torque biasing action means that ‘understeer’ is eliminated and traction is improved immensely. This will turn more of the cars tractive force into forward motion and ultimately make the car quicker. If power upgrades have been made to the car it will benefit even further by achieving more forward motion from the added power. A Quaife differential is an absolute must-have modification for any car which comes with an open differential out of the factory.

The Quaife limited slip differential requires absolutely no maintenance. It carries a lifetime warranty* making this product a true ‘fit and forget’ solution for improved traction and handling.

Proven in circuit and drag racing, rallying and road use, it is produced from Corus steel billets, and is CAD designed and CNC machined, then inspected to ISO 9001 standards.

Quaife is the most well-proven, established and thoroughly tested brand on the market. Accept no imitations!

Used by Ford, General Motors and Daimler-Chrysler as original equipment, no other manufacturer has these credentials.
