do you have to z the frame when bding an 85 f/s?

do you have to z the frame when bding an 85 f/s?

thanks,

im thinking it would make more sense to z or raise the front crossmember if your gonna b-drop it

no you dont,just go with upper and lower a-arms and 3 inch spindles,should lay out and clear 22's with ease

well right now we have it laying on the stock arms on 22s. literally the ground is touching them. and the stock arms are thick. so tubular lowers will make the frame lay?

No, you need to Z the frame, modify the crossmember, or buy an aftermarket one. (KP sells one now)
If you dont, the frame will not lay flat. if the frame isnt layed flat when you BD, you will BDing the truck on an angle. Pretty messed up way of doing things.

is that true for 88-96? say a 1500 chevy suburban?
