Achieve maximum traction and consistent power delivery with the Performance Engineering & Manufacturing Assembled Full Spool. Designed for the legendary Ford 9-inch rear end, this unit is the ultimate choice for drag racing and high-performance applications where equal torque distribution to both rear wheels is non-negotiable. This pre-assembled unit saves you valuable time and ensures professional-grade setup right out of the box.
A full spool eliminates the differential action, locking the axles together for 100% power transfer to the wheels. This is critical for preventing one-wheel peels and ensuring your vehicle launches straight and hard every time. The 3.70 gear ratio provides an ideal balance between quick acceleration off the line and usable top-end speed, making it a versatile choice for a wide range of racing classes. Built from high-strength steel, this spool is designed to handle the massive torque loads generated by high-horsepower engines. The precision assembly ensures smooth operation and long-term reliability on the track. Whether you are building a dedicated drag car or a high-performance street machine, this differential case is the backbone of a strong drivetrain. Trust in the quality of Performance Engineering & Manufacturing for your next build. Find all your essential performance drivetrain components at GGCRACING.
