Our online skate shop carries some of the most solid skateboard trucks available. We only carry reputable brands, so you know the quality always is from the top shelf.
Typically skate trucks consist of a base plate, hanger (the moving part of the truck to which your wheels are attached), as well as a kingpin (with a large nut) that holds these two pieces together. In addition, there are the bushings and washers.
The protruding part to which your wheels are attached is the axle. The discs on the shaft are called speed rings. They protect your bearings from wear and tear while helping to keep them clean.
