    Does the shackle flip cause the rear axle to move forward any? Since you are only lowering the rear end of the spring shouldn't this cause it to move downward on an arch thus pushing the axle slightly forward? Is this the reason for the invention of the zero rates? Also, I can't find the zero rates on the web site - did I miss them somewhere?

    Just curious, I'm going to be starting a new project and would like to eliminate my rear block.

    Whether the flip kit moves the axle forward depends greatly on what spring you use. With a stock spring, it's a negligible amount, usually 1/4" or so. With a deeper arch spring, it can be more.
    The zero rates are here: Zero rate page
    The reason we have the Zero Rate is to give guys more options, that's all. You can sure use them to move the axle back if you have a flip with a deep arch spring.
