Question - about rear shocks. NEED HELP QUICKLY!

[PARAGON]

theoretically then, the front should drop also. They are the same high pressure gas charged type that's on the rear.

He stated this will cause the rear to be lower

This sux because I really like the shocks. I remember seeing somewhere on a link here, that there is a 1" coil spring spacer that I could use. Anyone know where this link is? I will try and search on it.

Another option is a stiffer coil spring if anyone knows of some?

PM sent...

Phil, yours were probably worn out

Paragon, strange thing is that the front OEM shocks are not gas charged.

[Ed G.]

I think the front shocks are gas charged, when I removed mine they extended. They didn't seem like they had as much pressure though.

Found out some more info from Rancho. Rancho/Monroe actually makes the stock OEM shocks for the H2.

Paragon & Ed are correct, in that the front are also gas charged, but at a very low amount compared to the rear. (25-40# max psi)

Rancho is working with me and trying to find a solution. They are leaning towards the Monroe monotube (self-adjusting) 911508 for the rear and the 911507 for the front.

These are their H2 replacement shocks with pressures that are in the same ranges as the OEM shocks.

IMO, you are looking at this all wrong. Shocks are about ride quality. Monotubes are not going to come close to performing as well as variable valving and the triple tubed setup the 9000s have.

It sounds as though you are happy and fine except that your truck sags in the rear. This is a result of spring setting. Up the spring rate in the rear to accommodate and you will still enjoy the benefits that the 9000s offer.

There's just a huge difference when you go from one truck running 9000s to one that's running stock or even bilsteins. People run spring spacers in their coils all of the time and it's something I would seriously consider if I was you before I would sacrifice the ride quality the shocks provide.

Again, my opinion.

[tomp]

That ia what I would like to do. The ride quality, like you mentioned, is very nice. When I get home from work, I will try and find the spacers linkage. I think I saved it a while back.

[tomp]

Hopefully Paragon or Phil can answer this. Is there a safe amount of turns I can lower the torsion bars, that would not require an alignment? Say maybe 1 to 1.5 turns?

[tomp]

Cool, I am going to try 1.5 turns. I originally cranked them 4 turns and things are a little stiff. Now that the rear is lower and softer, I need to drop the front a hair.

[PARAGON]

Obviously this depends on where your truck is in relation to the jounce bumpers. My bars are up a few turns and still touch the top the jounce bumpers at rest. I doubt if I backed mine out that it would lower the front by much.
