Moser Engineering now offers the Wavetrac Differential for use in the Ford 8.8 rear differentials. This unit is designed to work with 33 spline axles and offers a smooth driving experience on the street while taking abuse at the drag strip.

Official Release:


Moser Engineering is proud to once again announce a partnership with Autotech Corporation. Moser Engineering will be the sole distributor in North America for the “Made in the USA” Innovative 33 spline Wavetrac Differential for 8.8” Ford style differential applications.

This is the strongest unit available and also boasts a Transferable Limited Lifetime Warranty that covers use in a motorsports environment. Moser Engineering was sold on the Wavetrac once we tested and tried to break the units in our fleet of race vehicles. They not only passed our tests but performed flawlessly.

With the economical horsepower available in today’s market it has been hard to supply a street capable differential that could not only handle the horsepower but give smooth and worry free operation even under drag race conditions. The “Made in the USA” built Wavetrac is the first reliable diff to be made available to the 8.8 Ford users that allows the use of a 33 spline axle and doesn’t have the noise and harshness of a locker style unit. These attributes make this the only choice for a street/strip machine.

This unit is different than any other torque biasing diff design because it works in low or no traction conditions that would stop other designs in their tracks. The Wavetrac units are made from 9310 steel gears run in a case-hardened Billet steel bodies and use high quality ARP fasteners. The unit is designed to be maintenance free and this means that as supplied new, the Wavetrac differential will perform a lifetime of service without maintenance or rebuilds. The unit is also customizable and if desired, you can alter the diff’s behavior to suit your needs using optional components.

This design really opens up the possibilities for dual purpose race cars. This 33 spline design when coupled with Moser Engineering Custom Alloy axles will give you years of worry free operation. With Moser Engineering’s expertise we can help you design a rear for your car that will not only handle the horsepower that you are building but make your car drive and handle life on the road as well as it handles life on the track. Combine this “Made in America” design with your “Made in America” Moser Axles and Housings and you will have a unit that will handle the toughest of conditions.
