Includes a set of 2, 1/2" hard plastic riser pads. These risers feature the 6 hole design so these will fit on virtually all deck and truck combinations. Perfect for Old School Skateboards, Cruisers, and Longboards. PREVENT WHEELBITE - Risers increase ride height which reduces wheelbite. Risers are great for those who ride loose trucks or big wheels. INCREASE DECK LIFE - Risers add a layer between hard aluminum trucks and the wood deck. INCREASE POP - Adding height to your setup increases the distance between your tail and the ground. The increase in distance allows for more downward force to be generated when popping your board.
