Moser Engineering Wavetrac differentials use a patented design to improve grip in low-traction conditions. Precisely engineered converging/diverging wave profiles are placed on one side gear and its mating preload hub. As the two side gears rotate relative to one another, each wave surface climbs the other, causing them to move apart. This imparts an increased normal force through the side gears, increasing the bias ratio as a function of load. The increase occurs automatically only when conditions find it necessary, and it 'reverts' back to its nominal bias ratio quickly and seamlessly, maintaining optimal drivability and performance at all times. Moser Engineering Wavetrac differentials are manufactured from the highest quality materials. With internal gears made from high-strength 9130 alloy steel, the bodies are machined from case-hardened billet steel.
