My experience is 15+ years (6 days a week/10-12 hours a day) specializing in suspension and brakes. After serving my apprenticeship in a Firestone store where I was designated to spend 10 hours a day in the alignment pit doing nothing but alignments, bushings and ball joints for 5 years I went to Goodyear for a little while than to Dodge to fix the more 3 dozen trucks waiting for buy back due to brake pull and chassis dynamics issues. I stayed another decade or so before moving on. Now I’m ort of on my own managing a fleet for a heavy construction firm working on my own suspension "consulting" business.
No gas charged shock absorber has the ability to raise chassis ride height. It may be that after installing them than lowering the car down it sat higher as the suspension was still unloaded but I think if you measured after a road test you would find no change. Gas charged shock absorbers all work under the same principle; although many have "gimmicks" like precision drilled holes in the upper piston or differently sized slots in the bore depending on how far up the bore the piston travels to change the dampening affect. There are no "bags" inside the shock body, some run twin pistons or different viscosities of oil, some have the ability to adjust to different road conditions via built in limiters or external adjustments but they are all the same fundamentally.
KYB gas-a-just are some of the stiffest shocks on the market (certainly not the best, but stiff) and I can compress them in my hands easily. How are they going to "lift" a chassis (even a light one)?
