Ron you will find some that say you do not need the rake kit (E-Z Steer) and if you are a weight lifter and can bend steel rods with you bare hands maybe so. If not, you will benefit from installing a rake kit. How much will depend on the places you ride and your riding style.
If you are mechanically inclined ZOOK can hook you up with a real high quality rake kit for way less then I've ever seen it anywhere else. I've installed four of his kits and they all are flawless. Call him at (334)648-0157.
Guess that means I'm for the E-Z Steer
