Allstar Performance is America's leading circle-track racing parts manufacturer. From aluminum panels and chassis components to brake hardware, steering boxes, and oval-track shock packages — every Allstar product is born from sprint car and modified racing experience.
The Allstar Performance full-size spool is the ultimate solution for racers requiring maximum traction and consistent power delivery. Designed specifically for the Ford 9-inch rear end with a 3.250-inch case, this 40-spline spool eliminates differential action, ensuring both rear wheels turn at the exact same speed at all times.
Spools are a staple in drag racing and circle track applications where traction is critical. By locking the axles together, this spool ensures that power is applied evenly, preventing one wheel from spinning independently of the other. The 40-spline design offers increased surface area and strength, allowing it to handle the immense torque produced by high-horsepower engines. Its rugged steel construction is built to withstand the extreme forces encountered during hard launches and high-speed cornering. If you are looking to optimize your rear-end performance and ensure reliable power transfer, this spool is a must-have component. Explore the full range of drivetrain upgrades available at GGCRACING.
