Wavetrac – Differential 2013-2018 Ford Focus ST MK3 EcoBoost 2.0T MMT6

If you’re tired of your stock open diff letting your Focus ST lose traction when you’re trying to get on the gas, this Wavetrac differential is one of the best upgrades you can make. It’s a genuine torque-biasing differential built in the USA that keeps power going to the tire with grip instead of just spinning the one with none — especially useful when you’re powering out of corners or driving on slick roads.

Instead of acting like a normal diff that basically shuts down when one wheel unloads, the Wavetrac uses a patented internal cam design so you stay moving forward with more control and smoother power delivery.

What makes it great
• Patented torque biasing keeps power where you need it most instead of just letting a wheel spin.
• Made with high-strength 9310 alloy steel gears and case-hardened steel bodies for durability under power.
• Built with ARP hardware for solid assembly you can trust.
• Includes a transferable Limited Lifetime Warranty for peace of mind.

Fluid Recommendation
Use factory specification Ford transmission fluid or a quality equivalent like Motul DCTF (approximately 2 quarts).
