USA Standard Gear Mini Spools are a low-cost traction option for vehicles looking for full-time lockup. The mini spool installs into a standard open carrier in place of the spider gears and delivers 100% power to both tires at all times. These units are not recommended for street-driven vehicles. Full spools are recommended for vehicles with large tires or high horsepower.
