The factory Chevy/GMC front hub units are notorious for having issues, even when running stock size tires. The billet front hub upgrade kit has been designed to replace the factory hub unit and bolt right on without having to modify your brakes or spindles. The GM billet front hub kit is the perfect upgrade to eliminate the stock wheel bearing issues these trucks have. This upgrade is fully CNC machined, as well as fully annodized. It utilizes a much wider bearing spread, crush sleeves, bearings, 14mm factory threaded wheel studs, 2” semi hollow snouts, and billet aluminum hubs. This is a direct bolt on replacement and will work with the factory brake calipers and rotors. All hardware and bearings included!
