Rear Suspension Air Bag to Coil Spring Conversion Kit For Hummer H2

Did not know they were going to be red, lol. They fit perfect, following the instruction from all of the feedback was great. No instructions in the box, could have been great. But I like the height, and easy of the install.

Product worked great! made the Hummer look good and ride good again, just make sure to purchase the 4 MOOG rubber paddings that go in top and bottom of springs part# K160072, when you pull the bags off make sure to pull off the lower black cups also after bags are removed.

I wasn't expecting the red, however, these did exactly what I bought them to do. The springs on my 2002 Suburban z71 were worn out causing the truck to sag and roll badly over bumps and in turns. Not even helper bags could solve the issue. These springs are much more substantial than the factory springs, in both coil diameter and height, equivalent of a small lift kit in the rear. These are also a progressive rate spring meaning the coils toward the bottom have a tighter coil than the top, which helps balance out the load over bumps and helps support the weight of cargo or trailers. The ride is firm but not stiff and definitely an improvement over the factory springs. Install was not terribly difficult if you have a good mechanical understanding, however it did require me to drop my rear axle several inches to install. Again this was on an 02 Suburban and is not exactly what these springs were intended to be installed on.

I've had these on a 2003 tahoe for a few weeks now. I was looking for 2 inches of lift while carrying a constant 400lbs in the back at all times. The z71 springs didn't cut it but these h2 Touring Tech springs I feel will. Initial lift was 2.5 inches in the back, but settled at just under 2 inches. The load rating is perfect, they help out with stability and ride quality to no end, as well as some fairly good flex for those of us that find ourselves far off the beaten path. The pictures attached have all suspension bolted in place, and still had one full inch until I hit bump stops.

Works perfect, buy isolators that fit.

Great product, easy to install, but needed spring compressor to shorten - easier to fit it in(stop dash board warning suspension service alarm)Remove Relay (location)=(1) Dash-Upper Plenum (2) Master Cylinder (3) Electronically Controlled Air Suspension Relay (4) Chassis HarnessDriver side rear electrical outlets to the air pump (unplug both)Disconnect the negative cable to the battery for 10 second - to reset the computer to not see the air suspension pumpDrive's great now

Installation was easy just had to unhook shocks and sway bar links. I did not purchase the rubber insulators and it fits and rides great.

I've extensively researched this matter of conversion from air bag to coil springs and finally settled for these. These are the cheapest you'll find as of June 2014. They work just fine. They came with some basic instructions that are straight forward. What they're missing are labels to tell you which one is left or right, top or bottom (reason why I deducted one star). ACCORDING TO GM DEALER I Called, the tallest spring goes on the left (driver side)and the shortest on the passenger side. The side of the springs were the coils are closer is the bottom. It can be hard to detect when you first look at them. The most I've ever done in a car is change tires but I was able to put these springs in with minimal assistance from my cousin. There are tons on details and videos on YouTube and forums about this installation. Hardest part is to safely lift the 6000+lbs H2. Make sure the truck is COMPLETELY SECURE AND SATBLE BEFORE DOING ANYTHING UNDER IT. The truck will appears a little higher with the new springs but I heard it will naturally adjust later. And (according to touring tech and I agree) you don't need the rubber spacers. I bought them but only used them on the top portion. The bottom doesn't fit as it was design for the air bags, not conventional springs.
