Need help finalizing my suspension setup for my '72 Blazer that will be running 44s. (Front) I plan to use 12" springs from a 73-87 Chevy with an ORD shackle and 1" zero rate. That nets about 13-13 1/2". Then I plan to build 2" drop hangers which hopefully will give me the 15" of lift that I want. A. Since I'll be using springs for a 73-87 Chevy, which are longer than my original springs, will this give me a bit more lift? B. What angle should I put my shackle at? Or will that depend on suspension travel (which won't be much, but I just want enough so that I won't rollover on curves at the mall ) (Rear) I will use 8" springs with an ORD 4" shackle flip, 6.0" HD shackle, and 1" zero rate. This gives me about 15" of lift also. C. With this setup will the tires be in the same place as before? Or will they be more forward or backward? D. Should the shackle be at a certain angle or at a 90*? Would like to run rockwells instead of my D60/14FF combo that is sitting & waiting for a suspension. E. Would I have to move the spring perches in on the rockwells with a WMS of 72"? Pinion angles, driveshafts, etc. are another story. Suggestions & constructive criticism welcome. Thanks.
