Most trucks are available in a few different widths, as well. Well, if it's too big, you'll look like a turtle, and if its too small, you won't be able to see them while riding. Your truck bolts should be flush with your board, so it depends on what size board you ride. In the past few years, there have been many different variations on trucks, to provide a bit of diversity to your board. For example, Tensor Trucks offer a plastic piece in the base plate, to assist with tricks like nose slides and tail slides.
Some companies offer a non-slip axle guarantee.
Like shoes, your trucks may take a few days to 'break in' properly, or for you to get used to them. Once they are broken in, though, you will get a feel for what you like and what you don't like. If it ain't broke, don't fix it. Click here to view the trucks we have available in Shop.
