Designed from a clean sheet, the new Wavetrac Differential brings current gear technology to 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. 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.
Each unit is crafted from the highest quality materials available. The internal gears are made from high strength 9310 alloy steel. Bodies are machined from case hardened steel billet. To complete the package each differential is built exclusively using high quality, high strength fasteners from ARP, the world leader in fastener technology.
