Removing air suspension, replacing with coils

[Egan]

Step 2: Disconnect the shock and swaybar from the axle. For the shocks, remove the bolts at the bottom. For the swaybars, it will be easier to remove the bolt up top.





Step 3: Lift the rest of the truck off the axle and/or lower the axle.

Step 4: Next I went after the air system itself, dropping the compressor and tank, disconnecting the wires, and cutting the airline feeds to both airbags as well as the tire inflator in the bed.





I just taped up the wiring harness and zip-tied it up under the bumper.

Step 5: Now take out the airbags. Simply turn clockwise and they will come free.



You should also remove the spacers the airbags rested on.

Step 6: Install the bottom spacers, install the coil springs with the top spacers on them, and then lower the H2/raise the axle.




Step 7: Reconnect the shock and swaybar bolts. 77 ft-lbs for the lower shock bolt, 53 ft-lbs for the swaybar bolt.

Finished product:





Once it settles in, I may have to raise the front end at the keys to level it out.

Great info! Thanks!

Is it possible to keep the compressor operational? A few uses for air a side from the suspension. Even though it is a week compressor system....

You could keep it in although I think it is controlled off the level sensors and switch in the cab. It probably weighs 30 lbs so I tore it out. I'm going to use the mount the compressors were on to mount my air horns, tank, and compressor. I'm going to see if I can tee the bed inflator port into the air line off the tank. But that write-up is for next weekend.
