Description
The Detroit Truetrac is a helical limited-slip differential that delivers consistent, predictable power delivery to both rear wheels without the maintenance demands of clutch-type units. If you’re running a Ford 9-inch rear and need reliable traction under hard acceleration without sacrificing drivability on the street, this carrier offers a proven solution that outperforms open differentials while maintaining smooth engagement during normal cornering.
Built for durability and engineered to handle sustained track abuse, the Truetrac’s helical gear design provides mechanical bias that improves weight transfer and reduces tire spin—essential for serious competitors and dedicated enthusiasts who demand consistent performance lap after lap.
