Wavetrac ATB Locking Differential (LSD) VW 02Q
MK5 Golf GTI & some TDI – 6-speed manual, front-wheel drive

Simply put: Wavetrac is the only gear-type differential lock on the market that does not lose traction even if one of the drive axles is lightened or loses load. This situation often arises, for example, during aggressive driving, when cornering on the track over bumps or on very slippery surfaces - more often than many people think.

How does Wavetrac affect performance?

Let’s take the example of a traditional gear-type lock (OEM, Quaife, MF, OBX, Truetrac, Torsen, etc.). You’re driving on a track and in a corner the inside wheel hits the curb and momentarily loses traction. This is normal in track driving. The problem is that during that brief moment the other wheel doesn’t get traction – the engine’s power isn’t being transmitted to the road.

Gear-type locks require a load on both axles to operate. Therefore, when one wheel becomes light, traction to the other wheel is momentarily interrupted. The result is that on the track or during aggressive riding, power is only transmitted intermittently to the wheel that is holding on.

Wavetrac is different. Its patented cam mechanism prevents loss of traction even if one wheel becomes lighter. The mechanism is able to create the necessary load inside the differential to compensate for the lost traction, allowing power to be directed to the wheel with better grip. The end result is smoother power transfer in corners, more predictable handling and an overall faster car.

Other benefits

• Patented carbon fiber Bias Plate for satellite sprockets
  In most gear-type locks, the satellite gears rotate directly against the housing, which changes friction with use and reduces the effectiveness of the lock. Wavetrac's carbon fiber plates maintain consistent performance throughout its life.

• Patented Wave Profile construction
  Eliminates near-zero load traction problems found in other ATB-type differentials.

• ARP bolts throughout
  Excellent strength and reliability in heavy use.

• Gears made of 9310 steel
  Mounted in a machined or forged steel housing for maximum durability.

• Designed and manufactured in the USA

Wavetrac – Smooth is Fast

Wavetrac is ideal for high-performance street cars that are also used on the track. It is highly durable, yet virtually unnoticeable to the driver and the car's traction control systems during normal driving.

On the track or in fast-paced street driving, it transmits power to both wheels without the driveability problems caused by traditional clutch locks – for example, there is no “pushing” that increases understeer.

Wavetrac outperforms other gear-type locks because it does not lose traction in the event that one axle becomes lightened – a situation that occurs surprisingly often in reality.

One of the most underrated features of the Wavetrac is its extremely smooth power delivery at the limit of traction . The patented design makes the power delivery predictable and smooth exactly when you need it most: in the middle of a corner at the limit of traction or on the exit when you are maintaining speed with the throttle.

In these situations, the difference is clearly felt by the driver. Wavetrac makes the car faster because it allows you to drive more confidently.
Smooth is fast.
