Matt Wolly is using Motive Gear Performance Ford 9" Ring and pinions both front and rear. Matt is a tough competitor, has the constitution of an ox and does what he says he's going to do. When Matt is not racing on rocks he's building buggy frames and all kinds of stuff at his shop. As a business owner and professional rock crawler Matt knows the value of hard work and performance parts that work hard. We can't say exactly how Matt has set up his Ford 9" assemblies, but one thing for sure- they are built to last.
