Wavetrac ATB Locking Differential (LSD) SKODA 02E
Octavia MK2 & MK3 DSG – 2WD, 25T crown wheel

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

How does Wavetrac improve performance?

Imagine a situation with a traditional gear-type lock (OEM, Quaife, MF, OBX, Truetrac, Torsen, etc.). You are driving on a track and in a corner the inside wheel hits the curb and becomes light for a moment. This is normal in track driving.

The problem arises because during that brief moment the other wheel is not getting traction – the engine power is not being transferred to the road. Gear-type locks require a load on both axles to operate. Therefore, on the track or during aggressive riding, a regular lock often only transmits power to the holding wheel intermittently.

Wavetrac is different. Its patented cam mechanism prevents loss of traction even if the inside wheel becomes lighter. The mechanism creates the necessary load inside the differential to compensate for the lost traction and directs power to the holding wheel. 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 ensure consistent performance throughout its life.

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

• ARP bolts throughout
  Very strong and reliable construction for 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

Designed specifically for high-performance street cars that are also used on the track, Wavetrac is highly durable, yet virtually unnoticeable to the driver and the car's traction and ride 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.

In addition, one of the most significant advantages of Wavetrac is its extremely smooth power delivery at the limit of traction . The patented design makes the power increase predictable and smooth exactly when it is needed most: in the middle of a curve at the limit of traction or on the exit when maintaining speed with the throttle.

For the driver, this feels like a clear advantage. Wavetrac makes the car faster because it allows you to drive more safely and confidently.
Smooth is fast.
