yes there is a member here that is local to me. I think he has been talking to someone on this board because they sent him to me. rear i ended up doing shock extenders and djm hardware kit but truck was rubbing brake lines on frame so didnt do free travel mod since its a ssbc brake set up and ssbc brakes loop way out.
Doing the extenders and djm endlink kit did help but still hes not happy. I told him once he fixes brakes and bracket is cut off we can see how it is. if he doesnt like it we can swap in the tbss airbags and he will be much happier.
I showed nate the pics of the rear brake lines im glad I caught it because the customer could have had a really bad accident.
Also there have been a few lurkers here that have done the same i walked them thru the set up and they kept the front bagged set up and put the rears on with some 5/32 to 1/4 adapters and then hooked it back up and in all cases for 150 bucks they said they love the ride. Maybe they could change the rear kit set up oh and lift... the tbss bags give 7 inches of lift if needed and they can tow 6000 pounds NO ISSUES.
If anyone here has any kit in rear and not happy and if you have the same holes on your 07 up as the pic I posted in the first thread trust me on this. Get the trailblazer ss airbags in rear with some 5/32 air line and a 5/32 to a 1/4 inch adapter and trust me you will be very happy with the combination just make sure to use the djm rear hardware kit along with my bumpstops and do the free travel mod.
I also did a suburban for i think these guys few months ago
http://www.sanfranciscolimo.com/ or sflimo.com was one of those companies.
they do tours to san francisco and load it up to airport and the truck i did a 1.5 drop on pass side and 1 inch on drivers (has the gm lean) in front but rear i did the belltech sp shocks and the tbss bags and the driver said right away ride was better and he could put 7 people in the truck and load i up with suitcases in rear and air up the bags and there would be no sag and with the occupants all in the truck ride was much smoother vs stock springs/shocks oh they ran the airlift wireless air to control it.
