I made a few extra kits as I made my own to raise my rear seat 2.5". You will get a little more than 10" at the front of the seat for clearance. This kit will come with a total of 8 pieces to raise the seat along with the seat belt mounts and all the hardware that you will need. Bolts and nuts are grade 8. Steel risers are .125 steel. $125 shipped in lower 48 states. PayPal accepted.
