Pardon the duplication above....I just watched your YouTube video and after lifting your front torsion bars more, it looks much more level. I think I see the issue with the discrepancy in lift height though....S10 springs will and did give you 3-4" of lift, and that's what you got. You stated that you have 7" of lift, showing the distance between the top of the rear tire and the fender at 7". To accurately measure lift, you need to have the van on a level surface and measure from the ground to the fender both before and after the lift. That distance should
increase by 3 1/2" after the lift, which looks like what you got. Yes, you have a 7" gap from wheel to fender, which is 3 1/2" more than you started with. And that's what was advertised on this site. Sorry you are unhappy, but just want to clarify for anyone reading this thread.
Once you go to S10 springs there is no easy way to lower the rear end. Stock springs and adjustable shackles or air shocks are a better solution for a mild or adjustable lift.
Once again, I think your van looks awesome in the YouTube video....maybe it will grow on you!
