Skateboarders and longboarders, this simple hardware kit might not look like much, but it's actually super important for keeping your ride smooth and safe. You get 8 axle washers (also called speed rings) and 4 lock nuts - enough to fully outfit two trucks. The washers are the real heroes here - they reduce friction between your bearings and the truck hanger, which actually increases your speed and helps your bearings last longer. They also protect your bearings from dirt and debris that can grind them down. The lock nuts are crucial too - they keep your wheels securely in place so you're not dealing with wheels falling off mid-ride. As you change wheels and bearings over time, your nuts can wear out and lose their ability to stay tight, so having fresh ones is always a good idea. Everything in this kit is standard size for 8mm axles, which covers pretty much every skateboard and longboard truck out there. The thread size on the nuts is 5/16 inch, and the quality is solid - these aren't some cheap parts that'll strip or break on you. Whether you're building a new board from scratch or just doing routine maintenance on your current setup, having these basic hardware components on hand is always smart. They're one of those small but essential parts that keep everything running smoothly and safely. Don't underestimate how much difference fresh washers and nuts can make in your ride quality!
