"I haven't loaded my trailer on yet with the new bags, but I think it will be a big help. The only thing I will mention is on installation don't let your suspension extend. Just jack it under the axel and then take off the tires. Installation was easy after that. The kit is excellent quality and I'm sure will do the job I want." —Al W from Parowan, UT bought a Firestone Air Bag Suspension Kit for a 2007 GMC Sierra.
