Yukon Mini Spools for 30 spline GM 8.5" axles are a low-cost traction option for vehicles looking for full-time lockup with quick and easily installation. Mini spools are designed to replace the spider gears in your standard open differential carrier to give you 100% power to both tires at all times. These units are not recommended for street-driven vehicles and are sold as off-road and race use only. For larger vehicles with oversize tires and/or high horsepower, we recommend upgrading to a full spool.
