I've recently purchased a 75 FJ40 that has been lifted via springs. I think it's lifted 4"...I'm trying to determine the actual height of the lift and ask for your help. The vehicle has 255/85/16 tires (swapping out for factory steel wheels), which measure 33.5" tall. The reference points I've used are at the underside of the front frame (near the bumper) and the underside of the back frame near the shackle mounts. The dimensions are both front 23" and drivers side back 26.5"/ passenger side back 27.5". I think the frame maybe bent in the rear...need to further investigate. Any help or guidance is greatly appreciated.
