I have information from GM on rear spring specifications that shows the average design load at camber height is 545-605 #, the camber height at design load is 1.58" negative and the average rate of deflection is 115 #/in. Doing the math then says that the average camber in the unloaded condition should be 3.16" to 3.68" positive. My old spring measures 3.70" psitive camber in the unloaded condition and the new springs I bought from Dr. Rebuild measure 5.35" positive in the unloaded condition and I measured the deflection rate and it is real close to the 115 #/in. It seems like these new springs will make the rear end sit up too high. Does anybody know what the unloaded camber number should be? Also, does anybody know of a shop in southern CA, preferably Orange County, that rebuilds and re arches leaf springs? Thanks.
