The mini longboard trucks can be described with one word, UNIQUE. We’ll give you some more information anyway... Our mini longboard trucks have grade 8 kingpins and axles just like the 7-inch trucks, which mean that they won’t break or bend. The mini trucks are 3-inches in length from axle end to axle end. Use these trucks on all of your narrow boards, and especially the minis. They pump and carve like crazy, don’t be afraid to loosen the nut on the kingpin if you are a lightweight.
