Wavetrac® designed from a clean sheet using state-of-the-art knowledge and engineering to be a better differential than any other. It uses a patented design to improve grip in low traction conditions.
Wavetrac® gives you quicker acceleration and faster cornering by driving both drive wheels instead of just one. And, it offers improved no-load performance when compared to other helical gear differentials on the market.
Patented Wavetrac® design automatically improves grip in low traction conditions. This feature is truly innovative and unlike any other torque biasing diff design.
9310 steel gears run in case-hardened billet or forged steel bodies. ARP® fasteners used throughout.
As supplied new, the Wavetrac® differential will perform a lifetime of service without maintenance or rebuilds.
If desired, you can alter the diff’s behavior to suit your needs using optional components.
