Quaife Sale - Automatic 135i 335i Only

[HP Autosport]

Quaife, The Ultimate Differential for your 135i and 335i(late model automatics only, after 09/2007 production date) with automatic transmission.


"The Quaife Automatic Torque Biasing Helical LSD Differential enables a car to accelerate more rapidly and corner faster. How?

Simply by getting the power to the ground.

With an normal open differential, fitted as standard on most cars, much precious power is wasted through wheel spin under acceleration. This happens because the open differential shifts power to the wheel with less grip - along the path of least resistance.

The Quaife differential, however, does just the opposite. It senses which wheel has the better grip, and automatically biases the power to that wheel. It does this smoothly and constantly, and without ever completely removing power from the other wheel.

In cornering, while accelerating out of a turn, the unit biases greater 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 differential also controls loss of traction when the drive wheels are on slippery surfaces such as ice and snow or mud, providing the appropriate biased traction needed to overcome these adverse conditions. Power is transferred automatically without the use of normal friction pads or plates seen in other limited-slip designs.

The Quaife ATB Helical LSD differential'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 differential is extremely strong and durable, and since it is gear-operated, it has no plates or clutches that can wear out and need costly and regular replacement. There is no maintenance required to the unit, so you can fit and forget.

The Quaife differential 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 cars towards its limits.

The Quaife differential is proven in everything from SCCA Rallying to drag racing and Formula 1. It provides autocrossers with such an advantage, it has become "required" equipment for a winning effort.

Expand your vehicle's limits with the Quaife ATB Helical LSD Differential!"

Automatics 135i come with a bolted differential, that means the Quaife is all you need and someone to intall it for you.

When you purchase the entire Quaife final drive, it's all set up and ready to bolt in. You are saving a good amount of labor there.

Quaife LSD only for manual R&R final drive and install LSD:

$1305 + 7-8 hours of labor at $139.67(our shop rate) = ~$2422.36

Quaife complete final drive for manual R&R final drive unit:

$2210 + 3 hours of labor at $139.67(our shop rate) = ~$2629.01

A difference of about $200! On top of that, you don't need to search for a shop who has the knowledge to set up the gear pattern and backlash for you, because it's already done. You are doing a final drive R&R only, just about any shop can do it.

Just the internals. You are keeping your final drive housing.

DCT is a different unit.

Since all DCT final drives have a welded ring gear, you will need a complete final drive.

Here is a low mileage unit for sale:
