Yukon Gear and Axle YP MINSGM8.5-30 Mini Spool for GM 8.5-Inch 10-Bolt, 30-Spline

The Yukon Gear and Axle YP MINSGM8.5-30 Mini Spool is a durable traction solution designed for GM 8.5-inch 10-bolt rear differentials with 30-spline axle shafts. This steel mini spool replaces the differential spider gears and locks both axle shafts together, helping deliver consistent power to both rear wheels in off-road, drag racing, and other high-traction applications where maximum drivetrain engagement is required. Its natural steel finish provides a straightforward, functional appearance while supporting reliable service in demanding environments.

Designed as a practical alternative to a full spool, the Yukon Gear and Axle mini spool installs inside the existing differential carrier and is suited for applications where controlled on-road handling is not the primary concern. Because both axle shafts remain mechanically coupled, this component is intended for competition, trail, and off-road use rather than typical street-driven vehicles. Professional installation and careful inspection of the carrier, axle shafts, bearings, and related differential components are recommended before operation.
