The Detroit Truetrac for Ford 9-inch 28-spline differentials is designed for hot rod builders and performance enthusiasts seeking enhanced traction without the complexity of full-locking differentials. This helical gear limited-slip differential is ideal for street and moderate strip use, providing consistent power transfer to both rear wheels while allowing for smooth cornering.
The Truetrac utilizes helical gears that create mechanical bias based on load and torque, automatically increasing lock-up under acceleration while remaining open during cornering. This design operates passively, requiring no driver input, clutches, or electronics, making it a reliable and low-maintenance option compared to active locking systems.
Ideal for classic Ford-powered muscle cars, restomods, or modern performance vehicles, the Detroit Truetrac ensures a direct bolt-in fit with 28-spline carrier internals, enhancing launch grip and predictable handling compared to open differentials.
