Description
High-Performance Mini Spool. The Richmond Rear Differential Mini Spool, featuring a 31-spline design, delivers a solid locking solution that improves traction by firmly locking both axle shafts together. It is engineered specifically for Ford 8.8" differentials equipped with 10 bolt open carriers, making it ideal for applications that demand enhanced durability and consistent power transfer. This mini spool is especially suited for racing and off-road use where maximum traction is essential.
Construction and Appearance. Manufactured from high-strength steel, this mini spool guarantees long-lasting reliability and performance. Its robust design can endure severe torque loads and harsh driving conditions. The product retains a natural steel finish, prioritizing function over aesthetics while providing resistance to wear.
Installation. Installing this mini spool is moderately challenging and typically requires differential disassembly. No drilling is necessary; however, professional installation is recommended to ensure proper fit and optimal operation within an open carrier setup.
Warranty. This product includes a 1 Year or 50,000 Mile warranty to protect against manufacturing defects and premature failure. Application. Compatible with 1986-2006 Mustang models, excluding V6 engines.
