Mechanics and car enthusiasts, this OTC wheel separator is exactly what you need for tackling stubborn wheels without damaging them! The tool comes with four different adapters - dual wheel outer, dual wheel inner (the long cupped one), single wheel (short cupped), and a flat adapter for various applications. What's really smart is how it applies pressure to the wheel rim instead of the delicate wheel lip, which completely eliminates bending or damaging your expensive wheels. The pusher end has two handy grooves - one for 16-17 inch wheels and another for larger 19.5-24.5 inch wheels, so it covers pretty much everything you'll encounter. The outer drive hook features a handle that makes alignment super quick and easy, plus it has a flat side that prevents the tool from turning while you're using it. This thing is built like a tank and feels super solid in your hands, unlike some cheaper separators that flex or feel flimsy. Whether you're working on regular passenger vehicles, trucks, or commercial vehicles with dual wheels, this tool makes the job so much safer and easier. No more hammering away at wheels and risking damage - just set it up properly and crank away. Seriously, if you do any kind of wheel work regularly, this OTC separator will pay for itself in no time by preventing costly wheel repairs and making your job way more efficient. It's one of those professional-grade tools that just works perfectly every time.
