BENEFITS
- Maximizes traction and minimizes wheelspin
- Proven in drag and circuit racing, rallying and road use
- Eliminates torque steer and snatching in fwd cars compared to conventional LSD
- Maintenance free design and retains standard axle lubrication
- Produced from CORUS steel billets throughout
- CAD designed and CNC machined then inspected to ISO 9001 standards
- Used by Ford, GM and Daimler-Chrysler as original equipment
- Massive range available, from Alfa Romeo to Volvo
- Beware of cheap imitations!
Reliability is total; the ATB Helical LSD 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 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 LSD the QUAIFE ATB Helical LSD unit requires no special maintenance or rebuilds, 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 ATB Helical LSD differential offers safe, reliable, winning performance – everything you’d expect from a QUAIFE product.
AS ENGINE POWER outputs increase ever further, the ability to utilize this extra performance becomes more important. Wheelspin may look spectacular, but such losses of traction waste time either from a standing start or exiting a bend, whether driving on the road, circuit, rally stage or drag strip. Fortunately, QUAIFE’s patented Automatic Torque Biasing (ATB) Helical LSD differential is an effective, well-proven, low-cost solution.
As a direct replacement for the standard, factory ‘open’ differential, QUAIFE’s ATB Helical LSD unit can transform the performance of your car. Unlike a conventional plate-style limited slip unit, QUAIFE’s ATB Helical LSD unit relies on gears, rather than clutch plates for its operation.
That means it’s much smoother in operation, because unlike a conventional plate-style 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 (especially of a front-wheel drive car,) 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 utilized in rear wheel drive vehicles, while QUAIFE ATB Helical LSD units offer significant traction advantages fitted to the front of four wheel drive cars.

Amazing difference, WORTH EVERY PENNY, Buy from these guys
First of all, I want to say, that this part is a special order item(it ships from England) and most places that offer them don't tell you it may take up to 6 weeks to get. I called Edge Automotive and for around $1400 bucks, I had it here in a week. Call them first to confirm these details before you order. I was hesitant to get it but after installing it (installed a stock LUK clutch and Fidanza flywheel) I took it out for a test drive in the rain. This differential makes the front hook up like it's all wheel drive and with virtually no wheel hop. Even on wet turns, the traction control didn't even kick in as I was punching the throttle. I also have a bunch of other mods and am going to get my car re-tuned in a couple of days which will be interesting and I will post my second review then. I am a very analytical and skeptical person and this is only the first night I have driven with it. But it by far is the single best performance modification that has yielded the most "fun" or "wow" factor and I can see it helping a lot in autocross events.
