Suspension raised to almost extended, used some soap on spools and spacers, slides like clockwork. A 2017 Cadillac Escalade giving out from tired air shocks and heavy weight got me almost on par with my normal load and with a little under 75% of my usual tools and my usual load carried on my back. The ride was not affected, if improved at all. Note * 2 sets used on each side, that's a lot of weight. On the next machine/vehicle I will install internal airbags and factory air shock absorbers. This is an easy and inexpensive upgrade.
