USA Standard Mini Spool For GM 8.5in / 28 Spline

Yukon Gear & Axle is well-known for its drivetrain components, and this USA Standard Mini Spool is a solid option for those looking for a low-cost way to get full-time traction. This mini spool replaces the spider gears inside a standard open differential carrier, meaning 100% of the power will always go to both rear wheels. This is a great setup for off-road vehicles where consistent grip is essential, like a Chevrolet Blazer or a Buick Regal used for trail riding.

Installing this mini spool changes the differential to a full-time locker. While this offers maximum traction, it's important to know that it's not recommended for street-driven vehicles because it can make turning more difficult and cause tire scrub. For serious off-road use, however, it ensures both tires are always working together, which is crucial when you're navigating tough terrain. This particular unit is designed for GM 8.5-inch axles with 28 splines.
