These are game changers! We have been using these silencers on our decks for a long time! They quiet the board rattle down and keep harware tight. By giving the truck a nice medium to sink into, your trucks will transfer less overall vibration from the road to the deck. This means your ride will be smother and hardware wont back itself off as easy.
Sold in sets of two, 1/16" thickness (compressable).
