Skateboarders, listen up! If your trucks are feeling loose or making weird creaking sounds, these Ace Trucks pivot cups might be exactly what you need. These are specifically designed for ACE AF1 trucks - each pack contains two pivot cups, which is perfect for replacing both trucks on your board. The 96a hardness rating is that sweet spot that gives you responsive turning without being too stiff or too mushy. What's really cool is that these are hand-poured, which means better quality control and consistency compared to mass-produced parts. When pivot cups wear out, your skating feels sloppy and less precise, so replacing them can honestly make your board feel brand new again. The installation is pretty straightforward if you're comfortable taking your trucks apart - just pop out the old worn cups and press these new ones into place. Whether you're doing maintenance on your current setup or building a new board from scratch, having fresh pivot cups makes a noticeable difference in how your board responds to your movements. It's one of those small skateboard parts that doesn't get much attention but actually has a big impact on your ride quality. If you want that crisp, responsive turning feeling back, these replacement pivot cups will definitely deliver!
