Description
Durable Traction Solution. The EXCEL from Richmond Differential Mini Spool is engineered to deliver uncompromising traction for performance-driven Ford Mustang builds. Designed for use with open carriers and 31-spline axle shafts, this mini spool replaces the differential’s internal components to create a full lock between both rear wheels. Ideal for drag racing and straight-line performance, it ensures both wheels receive equal torque, maximizing grip and acceleration.
Construction and Appearance. Crafted from high-strength steel, this mini spool is built for durability and long-term performance under high-load conditions. The robust material construction ensures resistance to deformation and wear, even in high-torque setups. Precision-machined to exact tolerances, it fits securely within Ford 8.8-inch (10-bolt) carrier housings, providing reliable operation in demanding environments.
Installation. As a direct replacement, the mini spool installs within the factory differential housing of compatible models without the need for extensive modification. Designed specifically for open carrier applications, installation should be performed by experienced technicians due to the precision required for correct differential setup and operation. Once installed, it delivers immediate improvements in straight-line traction.
Application. This EXCEL from Richmond Differential Mini Spool fits 1986-2004 Ford Mustang models. Excludes V6 models. It enhances vehicle performance by eliminating wheel slip during acceleration, making it ideal for racing or high-performance builds that prioritize forward momentum over cornering flexibility. A trusted upgrade for enthusiasts seeking maximum rear-wheel drive efficiency.
