These high-quality riser pads are made by Khiro and are 1/4′ – 1/2′ high. Riser pads, or risers, are hard plastic pads that can be inserted between the skateboard trucks and deck to raise the overall height of the skateboard. They are used as a shock absorber to help preserve your skateboard deck by reducing the risk for stress cracks where the deck and the trucks meet. NOTE: Black Khiro Angled Hard Riser Pads are sold in sets of two unless otherwise noted. Includes: Two (2) Khiro Angled Hard Riser Pads from Khiro. A good rule of thumb for choosing the right hardware to use with your riser pads is to simply add an inch to the height of the riser pads you’re using. For example, if you’re using .25′ riser pads, we recommend getting 1.25′ hardware.
