Many people think suspension setup is a mysterious black art. It's not!

At Race Tech you have choices:

  1. Buy our Gold Valve Kits, High Performance Springs, and Ultra Slick Suspension Fluids and install them yourself. (If you get stuck call your Tech Support 951.279.6655.) Hey, if you're really into it, check out our Suspension Seminars.
  2. Send your shock and forks to Race Tech or have your local Race Tech Center install them. You can also have your local dealer do the work.
  3. Have the work done by Race Tech track side at AHRMA events!


At Race Tech our customers' satisfaction is vital. We put it in writing.  ►Read More!
