Wavetrac DQ250 (20T) FWD 2WD 6-speed transmission Differential lock 10.309.185WK

Simply put - Wavetrac is the only differential on the market that does not lose all drive when an axle is unloaded.

Axles get unloaded during aggressive driving, cornering, extremely slippery surfaces, etc.
It happens more than most people think.

We won't go into torque bias ratios or the concept of how torque bias differences work at this point.

Let's move on to how the Wavetrac affects performance:
For example, you have a conventional differential (OEM, Quaife, MF, OBX, Truetrac, Torsen, etc.), you are on a race track for a track day and while cornering your inside wheel hits the curb. This is normal when riding on a racetrack. The problem is that for those brief moments when your inside tire is unloaded jumping curbs, your other wheel gets no drive - no power loss.

Differentials need to be loaded on both axles to work. The result on a racetrack (or when driving aggressively) is that a normal differential often only delivers intermittent power to the gripping wheel.
Now same track with Wavetrac: The patented cam device in the Wavetrac prevents loss of drive when the inside wheel is unloaded.

The device is able to generate a load in the differential (to replace the lost load when it happens), which can then be biased to the grip wheel - in the end providing a smoother power transfer through a corner.

This makes the car more predictable and faster overall.

Other benefits: Patented carbon fiber preload plate for the pinions.

In all other transmission type LSDs, the pinions run on the housing, which means friction varies from 0 miles to 100 miles, reducing efficiency over the life of the diff.

At Wavetrac the performance matches the Carbon Fiber Bias Plates! The patented shaft profile eliminates the effects of rideability issues at near and zero load found on all other transmission type ATB LSDs. ARP bolts used throughout for superior, faster reliability. 9310 steel gears run in billet or forged steel housings. Manufactured and designed in the USA

WAVETRAC:
Smooth is fast The beauty of the Wavetrac is that it is ideal for high performance street cars used on the track. It is very strong yet transparent to the driver and traction control electronics during normal driving.
On the track or in lively street use, it provides drive to both wheels without the handling problems that conventional clutch differentials cause (there is no tendency to push / understeer with a Wavetrac). The Wavetrac outperforms other differentials because, unlike them, it does not lose drive when one axle is unloaded (which is more common than you might think).
Finally, one of the most underrated benefits of the Wavetrac is its smooth power delivery close to the limit. Its patented design provides very predictable, smooth power delivery when you need it most - when things are at the limit: on the edge of traction mid-corner and using throttle to keep it there; or coming into a corner a little hot, but quickly back on it to maintain exit speed....
These situations are often subjective for the driver, but the benefits are tangible. The Wavetrac makes you faster because it lets you drive with confidence. Smooth is fast.
