Hummer H2For those who like a little more gleam to their Hummer, the H2 offers a similar rugged look as the H1, but as a lower cost, and with more added features, making it almost a massive luxury SUV.
@MixManSC I just came across your thread on the rear air sensor and level kit. I just had the front end done and leveled with the Kryptonite UCA an Fox shocks. Sits a little higher up front currently. I’m planning to run 24x12 on a 37x13.50r24. Front keys arent turned up very much.
Was curious if you could give me some more info on how you relocated the sensors. I love the air ride and the features that come with it. I believe a 1.5 in spacer or 2 in would do the trick. I think my front is set just right for my wheels/tires, just need to bring the rear up.
It is a bit complicated to raise the rear with the rear air ride..... You basically will need to have a GM Tech2 so that you can access the rear air ride module to monitor its parameters for one thing. With that you can determine the current voltage for the sensor on each side. This is your proper mid-point (it can change a small amount no problem). I basically used 2" coil spring spacers with the lower air spring centering cups mounted to the top of those. Then (after noting the above voltages for each sensor) cut each sensor rod in half, run a die down the rods and use a tube nut to lengthen the rod on each side. Then with a Tech2 connected and watching the rear sensor voltages adjust them in/out to get to the correct voltages. I cannot remember the exact sequence I did things off the top of my head but it also involved manually getting the rear to the exact height on some blocks.
@MixManSC Sounds like a big job. I could probably get access toa GM Tech2. My cousins fiance' works at the local GM dealer in town. Just not sure about the rest of it. Cutting the sensor and such. I really like the air ride option and keeping a trailer level, even though I dont tow much with it. I think I read online here that if you disable you have to pull a sensor from the fender liner to get rid of the "service air ride" light on the dash. I would think that if you did remove the bags it would also mess with the compressor hookups, am I right?
Yes, I'm not aware of any way to continue to have the accessory functions of the compressor with the air springs removed as it will be in an error state and as such will not allow the inflator switch to work. It sounds more complicated that it really is. The sensors are visible just behind/above each rear tire. There is a solid metal rod with a rubber attachment point on each end. One end is attached to the frame, the other to the moving arm of the sensor. The attached - images. On the one you can see the coil spring spacer with another black piece on top of it. The piece on top is the original air spring centering piece - it was where the much larger spacer is and now is bolted to the top of the spacer instead. The other photo if the air ride height sensor rod. The sensor itself is at the top with the movable arm. I just cut the rod in half and threaded it with a 1/4-20 thread die.
@MixManSC ill talk with a shop that I deal with on suspension lifts, etc. I have the tools and stuff to work on my Vette. Working on this 9k beast requires some serious jack stands and equipment. They may have some experience with them, not sure till I ask. Sounds like you lift the body up so you can access the bags, and the spacer, move the sensors and reprogram. Is that right?
That bracket can be moved but there are bumps cast into the control arms that assure that the brackets are positioned right and do not slip or move. I found a document I wrote up when I did mine. See the attached...
