Ford is known for building strong rear axle assemblies, most notably the 9-inch. But with the 8.8 ringing in at a strong second, it only makes sense for enthusiasts to modify them for more horsepower and torque. They’re a perfect unit to rely on for street/strip applications, and companies like B&M make components to beef them up.
