Partial front Suspension assembly

[Derek69SS]

...or more of a mock-up really. I'm trying to figure out if I can get my ride-height set right from the get-go. I hope my calculations are somewhat accurate.



I partially assembled it with no height adjusters installed (just the 9.5" 700# AFCO springs). The crossmember sits 2.5" off the floor. Adding approx. 1750 pounds of sprung weight, will drop it about 2.5".

(700# x 2 = 1400#/inch)
1750/1400 = 1.25" compression
1.25 x 2 (because the lower ball-joint is 2x the distance away from the pivot) = 2.5" lower
2.5 - 2.5 = 0" cross-member to ground. (almost low enough )

The height adjusters are 2.875" high at their min. height.
2.875" x 2 (lever of A-arm again)= 5.75" clearance at the crossmember

WAY TOO HIGH!!!! That's almost stock height

I'm thinking I should cut 3/4" off the height adjusters, and get it down to about 4.25".

Here is some more eye candy
