    Differences in \'67 vs \'69 Spring lengths?

    Is there a difference in the leaf spring sizes from '67 K series to '69-'72 K series, other than the fact that some trucks used 52" rear springs while others used the 52" rear leafs? Thanks in advance for all responses, Gary

    I think K/20 spring configurations were different from K/10s. Much Beefier.I know the '67 K/10 rear springs were longer two leaf sets compared to a '69 -'72. I can measure my '67 K/10 Suburban rear spring length and compare it to my '71 GMC K/5, if that would help. The Jimmy has a rear spring stack of about 5 layers, and shorter.

    I believe the 67 and 68s had longer rear springs and the spring perch is not in the center from front to back, unlike 69 and up. This is why you can not find rear springs(lift) for 67/68 trucks, nobody mass produces them.
