The XB-554 HD PROFESSIONAL is our newest product release (June 2020) and is the Professional Grade version of the XB-550 HD. It has all of the features and benefits of the XB-550, with a couple key upgrades that makes it an ultra-durable and stronger tool that will handle the most difficult large tire applications, and day-in-day-out commercial use. Specifically all of the wear points use Hardened Alloy Steel. The hardest working element: the female ram threads utilize a hardened 4140 alloy steel thread insert that can be replaced if it ever wears out. Also the top of the ram foot, ie. the ‘ram pad’ is also upgraded to 4140 steel. Along with Grade 8 bolts all around, and an extended 3-year warranty, the XB-554 HD PRO has addressed the limitations of the XB-550 when used on the most extreme applications like Skid Loaders and production environments like Mobile Tire Repair Service. The 554-PRO was designed to handle the BIG tires that you’ll find on farm tractors, agricultural and industrial OTR wheels, large trucks, military vehicles, etc. However, we created a patented configurable ram foot that can accommodate a large range of rim lip sizes, and it will still work on ATV/UTV. There are 4 different foot length configurations, so that you can get the feet as close to the Bead Seat as possible without touching the Bead Retainer, but still get good purchase on top of the Bead Bundle. Its still far more portable than any other large tire bead breaker, and much less expensive. Small enough to break the back-side bead of a tractor tire without removing the wheel! If you are a farmer, business owner, or a large vehicle enthusiasts; you can now can easily change your own tires whenever, and wherever you want.
