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 Wavetrac Differential is crafted from the highest quality materials available. 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.
I ordered the Wavetrac unit for my 2018 focus st. Still nearly zero torque steer. The traction change turns a great driving experience into a phenomenal one. Very pleased with the reasonable shipping cost. Too bad wavetrac doesn't include stickers. No one will ever know why it handles so much better now.
By far the best upgrade for the ST over anything else I have used. Why add power when you are just going to one wheel peel it away? LSD first, then add more power. Wavetrac all the way.
