Installed my Timbren kit on my 1995 dodge ram. I did not even have to jack it up installs real easy about 20 mins per side. I did not have the suggested 1" clearance between the rubber spring and pad only 1/2" {Leaf springs have so sag to them} thats with my fiberglass tonneau on the truck that will be removed. I put enough weight in so they were in contact with the rubber timbrens and did a test drive over some RR track and bumps, They sure firm the suspension up! {I should have no problem hauling a good load now thats for sure} I do think some new shock are in order for the frount as I do get a bit of dive when it hit the breaks but no bad. Can't remember when they were changed last so there do. Just thought I would give you an update. Jay
