Steve, This discussion won't be solved by just thinking about it..... So, why don't you just go out to your van tonight with some spacers, a jack, a ruler, spring compressor and a six pack. Open a beer, take a swig. Measure the compressed length of the spring. Mark the rear shocks compressed as they are now, jack a wheel up so its off the ground and mark its extended length. The difference between the extended length and the compressed length is the sag. Take a swig. Insert a spacer. The extended length of the shock shouldn't change since it is topped out. Lower the van back down and again mark/measure the compressed length the shock with the jack removed. Measure the compressed length of the spring (just the spring) with the spacer in place. Take another swig. Subtract the new compressed length from the old compressed length. The difference in compressed lengths of the shock before and after inserting the spacer should equal the thickness of the spacer and the length of the weighted spring should be the same....If not then your premis is right--drink remaining 5 beers. i'm thirsty, fred |
