Yukon Gear & Axle YP Mini Spool GM Spline

The Yukon Gear & Axle YP Mini Spool for GM differentials is a low-cost way to get full-time lockup. It replaces the spider gears inside a standard open carrier. Both axle shafts then turn together, so both wheels get 100% of the power at all times. Mini spools are popular for drag racing, off-road and other dedicated performance builds. They are also sometimes called differential mini spools or locked differential spools.

Key Features:

• Installs into a standard open carrier case in place of the spider gears
• Delivers 100% traction to both wheels at all times
• Economical option that gives the traction of a full spool
• Made from high-quality materials for strength and long life in performance use
• Built by Yukon Gear & Axle, which makes its parts to tolerances that meet or exceed OE specifications
• Available in GM applications with different axle spline counts and housing styles

Application Notes: Mini spools are intended for performance and competition use. They are not recommended for street-driven vehicles. For vehicles with large tires or high horsepower, Yukon recommends a full spool.

Yukon Gear & Axle is a respected name in aftermarket drivetrain parts. Choose the variant that matches your GM axle spline count and differential style.
