Quaife Limited Slip Differential, IRS Type 1 (33 Spline), QDF4R-33 is a direct replacement for the standard Volkswagen open differential. This unit is bulletproof, and will provide maximum traction for fastest acceleration and cornering. The 33 spline model uses stock CV Flanges and Seals for the output shafts. Unlike a conventional plate-style limited slip differential like the ZF, the Volkswagen Beetle 33T spline IRS Quaife ATB Helical LSD differential relies on gears rather than clutch plates for its operation, which means it is much smoother in operation! The Quaife progressively moves power to the wheel with more grip. These are a MUST if you want the most traction possible, SAFELY.
By getting the power to the ground! The Quaife Differential powers both drive wheels under nearly all conditions, instead of just one. With an ordinary open differential, a lot of precious power is wasted during wheelspin under acceleration. This happens because the open differential shifts power to the wheel with less grip (along the path of least resistance). The Quaife, however, does just the opposite. It senses which wheel has the better grip, and biases the power to THAT wheel. It does this smoothly and consistantly, and without ever completely removing power from the other wheel.
In drag-race type use, this results in a close to ideal 50/50 power split to both drive wheels, resulting in essentially twice the grip of an ordinary differential (they don't call open diffs "peglegs" for nothing).
In cornering, like in Hillclimb, Auto-X, or Road Racing, while accelerating out of a turn, the Quaife biases power to the outside wheel, reducing inside-wheel spin. This allows the driver to begin accelerating earlier, exiting the corner at a higher speed.
The Quaife also controls loss of traction when the front wheels are on slippery surfaces such as ice and snow or mud, providing the appropriate biased traction needed to overcome these adverse conditions. The Quaife Differential provides constant and infinitely variable drive. Power is transferred automatically without the use of normal friction pads or plates seen in other limited-slip designs, like the ZF.
The Quaife's unique design offers maximum traction, improves handling and steering, and puts the power where it is needed most. A definite advantage whether on the track or on the street.
The Quaife is extremely strong and durable and since the Quaife is gear operated, it has no plates or clutches which can wear out and need costly replacement.
The Quaife is great for street driving or racing. Racers don't have to put up with locking mechanisms or spools that tear the steering wheel out of their hands when cornering. Because it behaves like an open differential during ordinary driving, street drivers will have trouble telling it's there until pushing the car's limits.
The Quaife has been proven in everything from SCCA Rally to Formula 1. It provides autocrossers with such an advantage, it has become "required" equipment for a winning effort.
WARNING: You can NOT use a Quaife differential with a 3.44 R&P, the two are not compatible due to ring gear size.

Kit Contents:

The Quaife Limited Slip Differential is an Automatic gear-operated Torque Biasing differential. Sets of floating helical gear pinions (1) mesh to provide the normal speed differential action. (2) Center spring provides pre-load. In the event of a wheel slip, torque bias is generated by the axial and radial thrusts of the pinions in the pockets (3). The resultant friction force enables the driving road wheel and sun gear (4) to transmit a greater proportion of the torque. This effect is progressive, but at no stage does the differential lock solid. Hence the inherent safety of the Quaife Automatic Torque Biasing Differential.
