Wavetrac is 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.Internally, its gear tooth forms are optimized for strength and improved oil film retention over competitive designs. Our gear package is smaller, reducing overall mass, yet is more durable since particular attention was paid to the tooth strength – optimized for high torque conditions.Attention was also paid to the side gear/axle interface, putting as much material thickness as possible in this critical area – most important when power levels get high.The internal gears are made from high strength 9310 alloy steel. The diff bodies are machined from case-hardened steel billet. To complete the package, every Wavetrac® differential is built exclusively using high quality, high strength fasteners from ARP®, the world leader in fastener technology
