• Innovative:
Patented Wavetrac® design automatically improves grip in low traction conditions. This feature is truly innovative and unlike any other torque biasing diff design.
• Superior Materials:
9310 steel gears run in case-hardened billet or forged steel bodies. ARP® fasteners were used throughout.
• Maintenance Free:
As supplied new, the Wavetrac® differential will perform a lifetime of service without maintenance or rebuilds.
• Customizable:
If desired, you can alter the diff’s behavior to suit your needs using optional components.
The problem: Loss of drive during zero or near-zero axle-load conditions.
Zero axle load is a condition that occurs during normal driving but creates the most noticeable problems when driving in extreme conditions. Zero or near-zero axle-load is the condition that exists when there is ‘no-load’ applied through the drivetrain when one drive wheel is nearly or completely lifted (often in aggressive cornering). It also occurs during the transition from engine driving a vehicle to engine braking and back, even with both drive wheels firmly on the ground.
Here’s how that loss of drive hurts you:
1) If you lift a wheel, all gear diffs except Wavetrac®, will NOT power the other wheel.
2) During the transition from accel to decel, all gear diffs except Wavetrac®, do nothing.
During the transition from accel to decel, where you have near zero torque on the axle, even if the wheels are on the ground, the typical diff is unable to begin applying drive torque until AFTER the zero torque condition is over. While this condition is generally short-lived, the fact that most diffs can do nothing during that time means that there will be a delay once the zero torque condition stops – creating a reaction time in the driveline.
