We're getting ready for a big trip and I decided to give the 4108 Firestone Coil-Rite Airbag Helper Springs a try in the Chevy Trailblazer EXT from SDTruckSprings.com, http://www.sdtrucksprings.com/index.php?main_page=product_info&products_id=4438 . Customer service was great and shipping was fast. I ordered Sunday night and received them Wednesday. They looked and felt of good quality, including the optional union tee. I was missing a heat shield but I really only needed one so I didn't worry about it. Installation took quite a bit of wrestling to get them into the springs but I got them in there. I watched several youtube videos before hand in preparation including the Airlift videos. The Airlift's looked like they were more pliable, and were folded into a "hot dog bun" shape before inserting them into the spring. There was no bending these into a hot dog bun. If I had to do it again I would try removing the shocks. I even tried to "lube" the second air bag and spring using Windex but it actually made it much more difficult. I would be curious to try talcum powder. Updates to come after road tests with camper in tow.
