While the Ford 9” is known for strength and reliability, its pinion design sacrifices smoothness and efficiency - issues the 8.8” addressed over 40 years ago. The FN988 merges the best traits of both, offering a refined, high-strength differential solution with a 31-spline Truetrac, 1350-series yoke, and five gear ratio options. Engineered, tested, and proven by Detroit Speed, it delivers modern driveline control, durability, and performance for Pro Touring and high-output street builds. ENGINEERED FOR STRENGTH Detroit Speed’s FN988 Torque Arm assembly sets the standard for precision and performance in differential design. The integrated torque arm mount eliminates the need for additional brackets common in 9” axle housing swaps, improving the tight packaging constraints in 3rd\/4th gen F-Bodies. Each case is cast from high strength nodular iron and machined to exacting tolerances. Forged steel bearing caps further increase strength in high horsepower application.
