Our new molded foam seat insert kit is designed to add form fitting high-density padding to the bottom and lower lumbar of your current seat. Everything you need is included in the kit. Please note that this kit is designed to be used with a seat that fits the driver properly as is. If your seat is too large for you already you will need to purchase a larger volume kit.
