The Pig Piles 1/8" Skateboard Riser Pad is a 1/8" thick shock absorption riser pad for a skateboard. Riser pads help reduce stress where the trucks meet the board. When buying risers you should be sure your hardware is longer than the combined thickness of the deck and riser pad.
Riser pads are inserted between your skateboard trucks and deck to raise the overall height of the skateboard. They're used to avoid wheel bite, which can occur when wheels rub the deck when you're turning or performing tricks. The larger the wheels are, the higher chance of wheel bite.
