The Yukon mini spool for 10.5-inch GM 14-bolt trucks installs into a standard open carrier in place of the spider gears and provides continuous 100% traction to both wheels. As a low-cost traction upgrade, it’s intended for off-road or dedicated use; Yukon notes full spools for very large tires or high-horsepower applications where added strength is needed.
