    Default J bar rake?

    How much rake do you want typically in a modified? 4 bar 4 bar. And what does raising it up and down on the frame side do?

    Starting Point:

    Start with pinion end at:
    Ford 9" - Center Line of Pinion
    QC - 1 1/4" to 1 1/2" above pinion center line.

    Then set rake so left hand frame end is 7" higher than pinion end. Measure from center of attaching bolt to center of attaching bolt.

    Adjust as needed from there.

    Yup. Acts like a kickstand on a bicycle with more angle.
