If you feel your setup is too noisy and clattery, then a set of shock pads or risers might be what you need to get it all running smoothly again.
These Viper 1/8" riser pads will give you a small amount of distance between wheel and board, and help you on your way to rolling without wheel bites. On top of that, the vibration dampening effect they have will keep you on your feet, skating for longer, since they will be less tired.
The mounting points make it possible to use the Venom riser pads for both old school and new school truck mounting. Useable for both skateboards and longboards.
