Thread: Triangulated four bar-Ford 9"

Billy Shope was one of the original Ramchargers, a group of Chrysler engineers who revolutionized drag racing in the 60's. I enjoy reading his explanations of suspension geometry. Herewith is some of it....

Those are some good links (funny seems like the guy wants help but doesn't want to listen ). I'll have to take some measurements but just playing with the calculators it seems my top bar should angle down for 100% anti-squat . I'll check again later and post some pictures.

Another thought I noticed on Dons pictures they both have anti-sway bars (I think), should I put the one off the axle back on?? The more I read the more I get confused.

I don't know if this will show up but I got these measurements:
Wheelbase-120"
C of G (cam height)-20"
Rear lower arm-22", 9.5" front, 9.75 rear (depending on tire size, planning 30")
Rear upper arm- ?, 22" front, rear ?

It gives me a length of 11.2" and 19.44" up for the front pivot. Did I do this right??

I just came across a post over at Hotrodders that says the pumpkin on the 9" is cast steel, it's not is it???
