AIR SUSPENSION Options!?!

[tomp]

The SamCo coils provide 1-1.5" more lift in the rear, over the OEM coils. However, they are slighly lighter spring rate so if you tow - it is a good idea to add aftermarket air bags.

There is certainly nothing wrong towing with coil springs. I towed my RV for years with both the OEM and the Samco coils and never had an issue.

Installed myself. Got to raise the frame up enough that the rear axle will hang high enough when supported by a floor jack to remove the two lower shock mounted and the two upper sway bar to frame mounts. Now lower the floor jack and there will be plenty of room to remove to air springs. Caution must be used here, if you cut the two air lines things tend to do weird sh!t, just be careful. The air spring has a anti rotation catch on top that when push down will allow you to turn the spring and remove it. The new coils come in a left and right spring with both needing to be "up". To me and the way I installed mine was that the drivers side of the truck is the LEFT side. Read some of the descriptions in the service manual to find out. The job for putting in the coils took about a hour.

The work of removing ALL compressor related parts, wires, sensors, plugs and even the ride height button took the rest of my weekend tracing wires was the hard part but I am so OCD that I wanted it all gone .

Thanks for all of the info fellas. I don't plan to remove the air system entirely as I want to keep it for rear cargo use, so I won't be pulling it all out

We will just be removing the airbags and deaf-heading all of those lines. The compressor will stay as well as the lines to the cargo area.

I am making a hybrid of sorts.

Where do you get these Samcro springs and how do they clare in price to stock coils?

SamCo rear coil springs for the rear of an H2 provide approximately 1/2" to 1" of lift for the rear of your H2 Hummer, compared to the factory rear coil springs. They also provide the potential for more wheel travel, as they were designed for pre runners and race H2's. The springs have a 2.5" longer free length, but less spring rate than the factory springs to provide a ride quality similar to the factory air bag suspension. The additional free length would allow for about 20% more wheel travel with the use of longer shocks and refabricated shock mounts. Sold in pairs.

Cool option, but they seem awfully expensive versus stock as they only provide for .5 to 1" of lift and only allow 20% more flex when the vehicle is fitted with longer shocks/new shock mounts.

I replaced my airbags and now my Service Air Suspension warning won't go away. Anyone find a permanent solution to this? I've already tried removing the fuse in the front left wheel well.

Yep, depending on teh year, you either need a new pcm OR they reflash for 3 issues. I'll get you list when I get mine done. The Castlerock HUMMER dealer is going to do mine. 06 gets re-flashed.

Edit: Did you remove your bags for springs ? I have been reading through your post here and am a little confused. This post says you replaced your air bags, http://www.elcovaforums.com/forums/s...t=38979&page=2 to me that means you had new air bags installed but I guess it could mean you replaced them with coil springs (sorry, I am a little slow on reading between the lines) . But, I went over to the "other" site you said that you put springs in, if that is the case, try unplugging the compressor control module in pic below, remove the relay completly under the fenderwell and disconnect the battery, the light should go out.

P.S. Nice looking truck from what I've seen at the other site.
