VJ Accessory Combos include: skateboard trucks, skateboard wheels, skateboard screws, skateboard spacers, skateboard bearings, and skateboard riser pads. The skateboard trucks are light, stable, and resilient. They offer 6-hole baseplates, which will fit both the old school pattern and the new school pattern. The skateboard street wheel diameter options are 52mm up to 54mm with 99a durometer hardness. The hardness of the wheel will provide a super smooth ride on the street and allow the board to turn and pivot smoothly when executing tricks at the park. Our ABEC 7 bearings steel balls are chrome steel that will turn faster than other regular carbon steel balls. Whether this is your first time with completely custom skateboards, or you are an experienced skateboard builder, this combo will have all the necessary parts to help complete your build.
