Does anybody have any experience with these? I'd like to hear opinions on this type of shock as well.
I've read that I may have to relocate the air valve because of its proximity to the tailpipe, did anybody else have to to this? If so how?

wouldn't it make more sense to move the tailpipe? Maybe do a down turn right off the muffler? As for the shocks I know nothing about them, other than they look expensive enough to justify reworking the exhaust rather than the air valve...

I currently have a them on my jeep. 1. It raised the sagging springs about 2"
2. I keep about 3-500 pounds in toold and parts in the back.
Only problem is that i had an issue with my driver side air shock rubbing the coiled hard brake line that goes to the driver side caliper. It wore a hole in it but they have lifetime warranty so it was swapped out for free. Its also not a bad ride.

installed these shocks with a set of new dorman leafsprings (all purchased from rock-auto). tossed the rear stabilizer bar and currently running the shocks at 35 PSI. The ride is much smoother since my other springs sagged severly. Even with the new leafs, airing up the shocks to 35psi lifts the rear an inch and 2 1/2 inches at 70psi. I probably wont be riding on more the 40psi unless towing. In the instructions it tells you to mount shocks with valves towards center of the vehicle, but the tailpipe would have rubbed so passenger side shock is mounted with valve facing out. I ran the lines through the frame and installed the tee valve (fill valve) inside the vehicle near the spare tire.

Kinda hard to see but you get the idea. I ran my air lines along the trailer hitch and gas tank. I took off my rear side plastics on the bumper and used one of the existing holes to mount my fill valve. With about 3-500lbs of tools in the back i run 75-100psi. The ride is now comfortable unlike before when my leafs were sagging so bad. It also gave me higher than stock rear ride height with these.

Nice! Mine are black too (expected white from all the pictures I had seen but no big deal). Im interested to see how these shock will fare here with manitoba's harsh winters. From your pics looks like you used the stock lower shock studs. As one of mine broke when removing the old shocks I installed one of the bolts that came with the kit (looks to be of good quality). Also two of the upper shock bolts broke both on the drivers side shock. Pounded out all of the spot welded nuts (drivers side and passenger) and installed new. I installed the fill valve inside as it is only plastic and did not want to risk damaging it.
Paid 54$ for the set from rock auto and with tax and shipping came to 75. Had I bought these here would have cost me 128$. I'll post pics sometime this week

Finally able to take some pics after first getting new camera. First picture is of the left shock. The air line runs along the frame and up through a whole near the left taillight.
Second Picture of the right shock. Air line runs through a small whole in the frame bout 2" back from the shock. Along the inside of the rear bumper and through same whole near left taillight.
Third pic is where I mounted the tee valve. Well protected from the elements
