Product DescriptionMoser Ultimate 9″ 31 Spline Axle & Differential Package

Moser Custom Alloy Axles are without question the best in the business. We begin with premium quality “MADE IN THE USA” Alloy Steel that is forged right here in Portland, Indiana just blocks from our manufacturing facility using Moser designed tooling, induction heat-treated to optimize torsional strength, and 100% magna fluxed. This process not only gives the axle strength of a “race only” axle but makes it ideal for street use as well. The axles are specifically designed and engineered to take the stress and strain of both racing and high performance street uses. Our axles can be made to fit virtually any rear end setup. All popular bearing sizes and bolt pattern combinations are available. If your future plans call for a narrower rear, Moser Custom Alloy Axles can be shortened and resplined to fit your needs and bolt pattern changes can also be made.

This kit also includes the Revolutionary Wavetrac differential. 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 9” users that allows the use of a 35 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.

Also included are the axle bearings, studs and retainer plates along with a complete setup kit to install your new Wavetrac unit.

Highlights:

  • Strong enough for racing applications but smooth and quiet for street use
  • Fits almost every rear-end setup
  • Works in low and no-traction conditions
  • Maintenance free
  • Customizable with optional components for your individual driving needs
  • Transferable Limited Lifetime Warranty for motorsport uses
