    Thumbs up Suspension drop reference

    Here is the way to take the measurements, and I would like to thank Spike for his photos.

    Front



    Rear



    Measure from the centerline of the wheel up (plumb) to the fender lip. Any other measurement doesn't count. 1/4" accuracy is good enough.

    *EDIT:* The current base line measurements for 02-03 trucks (fender flairs) is 18" Front/20" rear.

    Provide:
    Manufacture and front drop type / Manufacture and rear drop type
    Measure front/measured rear
    Make sure you have atleast 200 miles on the drop before posting
    (tire and wheel sizes don't matter)

    Ground Force 1/3 kit 9904 goes in tommorow,
    pre drop measurements are
    19 3/8 rear and 17 3/8 front

    3 days later I got the truck back . Looks really good. think there is still gonna be like a half inch of rake but it looks much better. will post new measurements after a couple hundred miles and a comparison pic once my web server comes back up--

    265 miles later measurements are 16 3/8 front and 17 rear for a net of 1" front and 2 3/8" rear.
    Yeah I know dirt!!!! It was raining when i picked it up. Rest assured its been cleaned off!!!!!!
