Question - about rear shocks. NEED HELP QUICKLY!

Don't do a thing until tomorrow. If you're not happy, be prepared to remove them.

There are too many alternatives out there for you to not be happy.

Pull them and get something else.

That sucks.

That is really surprising to me that you lost height with a shock swap. The shocks are not meant to suspend the vehicle but to dampen the suspension movements. I can't imagine a shock (other than a true air shock) changing the ride height of the rig. I guess if its lower, its lower but its just really weird.

gas charged shocks are "charged" for only one reason. To keep the dampening oil in suspension. The compressed gas inside the shock keeps the oil from frothing.

The negative side of that is that it forces the shock to full extension. But it's not enough to pick up a vehicle.

Put it this way, the pressure in the shock is low enough that one can simply push the shock back into compression. That is not enough "power" to lift the truck which would likely be over 1500 lbs at the to rear corners.

Back to the height of the vehicle when you removed the shocks, that doesn't really mean much. The height is dynamic as you move and the shocks work themselves as the truck moves over rough surfaces. Drive around on the new shocks for a few days and if afterwards you still don't like the way the truck looks, get some coil spaces to raise the rear.

IMO, it's dumb to sacrifice ride quality and function of the suspension just to have the truck sit level when it's still and the Ranchos are the shiznit.

TBs were adjusted few thousand miles ago and alignment already done.

The Ranchos did not appear to be gas charged, as I had to pull out on them to get them the right length to fit.

Seriously though, when I removed the rear shocks, the side I was working at that time on dropped down at least an inch or more. I can also tell it sits lower in the back now with the 9000s on.

the remote reserviors are for sure. The 9000's aren't, I don't think. Some shocks like Ranchos are low pressure charged but the crappy shocks like the stock shocks are high pressure charged, therefore push apart when you take them off.

Can anyone confirm if the OEM shocks from an H2 with Rear Air Suspension are gas charged or not? I am wondering if they put these gas charged shocks on just non-air H2s since they dont have the air bags.

gas charged are on air-ride as well, same shocks.
