📞 Ask an Expert!Wavetrac is the only gear diff on the market that does not lose all drive when one axle is unloaded. Axles become unloaded during aggressive driving, track cornering, extremely slick surfaces, etc. It happens more than most people realise.
We won't go into torque bias ratios or the concept of how torque biasing diffs work at this point. Instead, let's get to know how the Wavetrac affects performance:
For example, you have a conventional gear diff (OEM, Quaife, MF, OBX, Truetrac, Torsen, etc.), you're on a race track for a track day and during cornering your inside wheel bumps over the curbing. This is normal for track driving. The issue is that, for those brief moments your inside tyre becomes unloaded when bouncing over curbs, the other wheel is not getting drive – means power is not effectively transferred. Gear differentials need load on both axles in order to function properly. The result on a track (or during aggressive driving) is that there are many times when a normal gear differentials supplies only intermittent power to the gripping wheel.
Now, consider same scenario with Wavetrac: The patented cam device in the Wavetrac prevents loss of drive when that inside wheel is unloaded. The device is able to generate a load inside the differential (to replace the lost load as it happens) that can then be biased to the gripping wheel - in the end making more consistent power delivery through a corner. That makes the car more predictable, and faster overall.
Other benefits
- Patented carbon fibre bias plate for the pinions. All other gear type LSDs run the pinions on the housing, meaning the friction from 0 miles is different to 100 miles, thus effectiveness is reduced over the life of the differential. With the Wavetrac performance is consistent with the Carbon Fibre bias plates!
- Patented wave profile eliminates the effect of a near to and zero load condition drive ability issues found in all other gear type ATB LSDs.
- ARP Bolts used throughout for superior faster reliability.
- 9310 steel gears run in billet or forged steel bodies.
- Manufactured & Designed in the USA
WAVETRAC: Smooth is Fast
The beauty of the Wavetrac is that it is ideally suited to high performance road cars that see track use. It is very strong, yet transparent to both driver and traction control electronics during regular driving. On the track or in spirited road use, it provides drive to both wheels without the handling issues that traditional clutch type differentials create (there is no tendency to push/understeer with a Wavetrac, or noises).
The Wavetrac outperforms other gear type differentials because unlike them, it won't lose drive when one axle is unloaded (which happens more often than you'd think).
Lastly, one of the most underrated benefits of the Wavetrac is its smooth delivery of power near the limit. Its patented design makes for a very predictable, smooth addition of power when you need it most - when things are at their limits: 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 to the driver, but the benefit can be felt. The Wavetrac makes you faster because it lets you drive with confidence.
FAQs
What vehicles is this Wavetrac differential compatible with?
This differential is designed for VW Golf R (MK7.5 and MK8) and Audi S3 models using the DQ381 7-speed DSG AWD gearbox. Always confirm your gearbox code (0GC / DQ381) before purchasing to ensure correct fitment.
Is this differential suitable for high-power or tuned vehicles?
Yes, it is built using high-strength 9310 alloy steel gears and a robust housing, making it suitable for high-performance and tuned setups where durability and consistent power delivery are important.
Will this differential affect daily drivability?
No, Wavetrac differentials operate smoothly during normal driving and do not introduce harsh engagement. They only actively bias torque when needed, so everyday usability remains unchanged while performance improves under load.
Does the Wavetrac differential come with installation hardware?
Yes, it includes high-quality ARP fasteners (including ring gear bolts), which are designed to provide secure installation and long-term reliability under load.
