Independent Risers Black 1/4 .25 SetThese high-quality riser pads are made by Independent and are 1/4" high. Riser pads, or risers, are hard plastic pads that can be inserted between the skateboard trucks and deck to increase the space between your wheels and your board. If you want to try out some bigger wheels, hard riser pads can absolutely make that happen. Just remember that if you want to install riser pads to your board, youll want to increase your hardware length as well. 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 youre using. For example, if youre using .25" riser pads, we recommend getting 1.25" hardware.Click here to view our entire selection of Independent products
