I am having problems with my air suspension of course so I want to get rid of it in favor for springs. I have an 05 H2 with a 6 inch fabtech lift and was wondering what I need to order. Do I need just the fabtech springs from a lift kit or do i need some sort of mounting hardware. Thanks!

 

I just changed over as well. Got my Fabtech six inch lift coils and then ordered the rubber insulator pads (4 each) from GM. You don't need anything else. I had the computer reprogrammed so the check air suspension warning did not keep going off. You can go without the insulators, but then the springs would be metal to metal.

 

Thank you very much! Can't you just pull a fuse to get the "service air suspension" to quit blinking?

 

No. You will still get the "check air suspension" warning over and over. I read about people doing all sorts of different tricks, but eventually it has to be done by some tweaking in the PCM.

 

Ok. How hard was it to put the new springs in?

 

I bought some metal hose crimps and plugged up both hoses to the old air ride set up. Then had a peron on each sensor which is visible from the wheel well mounted to the frame. Have them both start all the way down pointing towards the front of the truck. shut off truck and restart and move the sensors up an inch, shut off restart and continue process til the service light goes off. Then zip tie in place. Worked for mine and I have been going for 4,000 miles no problems. Plus I still have the function of the compressor.

 

Hello,

Read your post about converting to coil springs with a FABTECH lift. I am looking to do the same thing. Was wondering how it went? Are the 4 insulators all you need with the springs? Any towing issues if you tow?

Hello there, owner of a 2004 H2 (bought it in 2004 March), and happy with the truck. Recently had air suspension issues, so got the airbag replaced. But the truck is still losing air. I'll troubleshoot it, but wanted to know if anyone has tried to build a brand-new air compressor system for a Hummer H2 like this one: https://rebuildmastertech.com/hummer...t-89060581-1/?

As the truck crosses the 22-year mark, it might be time to rebuild some of these critical sub-systems from scratch, so just wondering.
