      Description

      Maximize Traction with a High-Performance Mini Spool. The Richmond Rear Differential Mini Spool is the perfect solution for Mustang owners looking for enhanced traction in high-performance applications. This component replaces the spider gears in the differential, ensuring full power is delivered to both rear wheels simultaneously, making it ideal for drag racing and off-road builds.

      Engineered for Strength and Reliability. Made from high-strength steel, this mini spool is designed to withstand high torque loads and aggressive driving conditions. By eliminating the need for a limited-slip differential, this cost-effective upgrade provides consistent traction without the added complexity of clutch-based or gear-driven limited-slip units.

      Installation. This product requires professional installation and proper setup within the rear differential.

      Application. This Richmond Rear Differential Mini Spool fits 1986-2006 Mustang, Excluding V6 Models.
