Yukon Gear Mini Spool for Ford 8.8" Axles (31 Spline)

Enhance your vehicle's traction with the Yukon Gear Mini Spool, specifically designed for Ford 8.8-inch rear ends with 31 spline axles and a 7/8-inch cross pin. This mini spool is an economical solution for achieving full-time lockup, ensuring 100% of power is delivered to both rear wheels simultaneously. It's engineered to install directly into a standard open differential carrier, replacing the spider gears to provide this aggressive traction characteristic.

Key Features and Benefits:

  • Full-Time Traction: Delivers constant power to both rear wheels for maximum grip in off-road or performance driving scenarios.
  • Cost-Effective Upgrade: A budget-friendly alternative to more complex locking differentials.
  • Direct Fit Installation: Designed to fit Ford 8.8-inch differentials with 31 spline axles.
  • Durable Construction: Built to withstand demanding conditions, though not recommended for street use.

Important Considerations:

Due to its nature of locking both wheels together, the Yukon Gear Mini Spool is not recommended for vehicles primarily driven on the street, as it can cause tire scrub and increase drivetrain stress during turns. For vehicles with significantly larger tires or high-horsepower applications, a full spool or a selectable locker might be a more suitable option. This product comes with a one-year warranty against manufacturing defects, offering peace of mind with your purchase.

This mini spool is compatible with a wide range of Ford and Mercury models, including various years of the Bronco, E-250 Econoline, F-150, LTD, and Cougar. Please verify fitment for your specific vehicle.

Get the ultimate traction for your Ford 8.8" differential with this reliable mini spool from Yukon Gear & Axle, available at GGCRACING.
