High-Performance Mini Spool for Ford 9-Inch

Achieve consistent traction and power delivery with the Allstar Performance 31-spline mini spool. Designed specifically for Ford 9-inch rear-end housings, this mini spool is a cost-effective way to lock your differential for maximum performance on the track. By eliminating the differential action, you ensure that both wheels receive equal power, which is essential for drag racing, circle track, and other competitive motorsport applications.

Technical Specifications

  • Compatibility: Ford 9-inch rear-ends
  • Spline Count: 31-spline
  • Material: High-strength steel
  • Type: Mini spool
  • Application: Racing only

The Allstar Performance mini spool is crafted from durable steel to withstand the high torque loads of racing environments. It is a lightweight and efficient alternative to a full spool, offering significant traction benefits without the added complexity or cost. Installation is straightforward for those familiar with Ford 9-inch differential setups, making it a popular choice for racers looking to improve their launch and cornering consistency. Because it locks the axles together, this part is intended for off-road or track-only use, providing the predictable handling required for competitive driving. Its precision-machined splines ensure a tight fit with your axle shafts, reducing wear and preventing slippage under load. Whether you are building a budget-friendly race car or fine-tuning your current setup for better traction, this mini spool is an essential component for your drivetrain.
