Wavetrac Ford 8.8" torsional differential fits the 2015 Mustang GT and Ecoboost and V6 models. This is the only torsional differential manufactured that works in No or Near No-Load conditions. The Wavetrac is a stronger more advanced design then a standard type 2 Torsen helical diff that comes from the factory. Patented Wavetrac design automatically improves grip in low traction conditions. This feature is truly innovative and unlike any other torque biasing diff design. Heavy Duty and maintenance free!!

Product Features

  • Made in USA
  • Unlike other gear driven diffs, when unloading a wheel, only the Wavetrac will still put power to the other wheel.
  • Lifetime Warranty is Transferable.
  • Functions under both acceleration and deceleration (most others only operate on acceleration).
  • Non-Intrusive: No more "fighting the steering wheel" in low speeds or tight turns compared to a spool/clutch type diffs.
  • Maintenance Free: No parts to replace - No oil to change.
  • Super Durable: Larger gear to housing interface. Billet steel housings. 9310 alloy steel internal gears.
  • Direct replacement for factory differential.
  • Manufactured with ARP Fasteners.
  • Smoothly biases power to drive wheels seamlessly in between acceleration and deceleration. NO DELAY!
  • Smaller gear package to reduce mass. Higher tooth strength increases durability.
  • Innovative wave design of preload hubs to gear interface means Wavetrac works in zero load or near-zero load conditions.
  • Works with existing traction control/ABS electronic systems seamlessly. 
  • Wavetrac Fluid Requirements: 75W90 Motul Gear 300 (100118) or 75W140 Motul Gear Competition (101161). 

The Wavetrac is the only differential that can automatically add more load internally when it’s required. In the case where both wheels are on the ground during zero axle load, such as during a transition to deceleration, the Wavetrac device is able to prepare the drivetrain for when the zero torque condition stops, eliminating the delay seen with ordinary gear diffs. What this means for you as a driver is that power is delivered to the gripping wheels for more time and in a more constant manner making you faster and improving stability.

The Wavetrac truly is different - and its innovative features can make a real difference in your car’s performance.
