Long term review 2003 K1500 the good, the bad, and the ugly
Suspension Connection is great to work with. The Firestone kit is simple to install. Rather than install a compressor, I opted to drill two holes for the Schrader valves through the bumper above the spare tire access port. It helps to us a carbide drill to get through the chrome. This airbag system greatly improves handling with carrying moderate to heavy loads, and while trailering. I've pulled a 7500 pound trailer twice a year with this system since 2005. The airbags did develop some leaks which were covered by Firestone's warranty after 5 years of use. When replacing the airbags make sure you use Loctite thread sealer on the bolts if you are re-using the same bolts. The bolts provided in the kit originally had thread sealant on them. Since this is my daily driver, and I don't haul heavy loads often, I'm a little disheartened that both lower brackets failed. To my surprise Firestone does not warranty the lower brackets! It is clearly a design problem as the brackets fail along the brake press formed 90 degree bends. The choices are buy new brackets, repair the old ones, or fabricate better ones. I've done the later two. All-in-all, this is a great set up if you know what you are in for. This is not a install and forget system. All of the components of this system should be routinely inspected...especially before a long haul. In hind sight, I would recommend installing a compressor and beef up the lower brackets before installing.
