Did a custom install for a customer of mine . Installed a rear Firestone Air helper kit on a 2020 GMC Sierra 2500 Denali so while pulling his 5th wheel camper the truck wouldn't sag down in the rear. The Firestone kit was purchased elsewhere. But it came with tire valves to put on a bracket and zip tie to hitch. So I made a switch panel and installed inside the bed (customer didn't want the on board compressor system) So I a pressure gauge, air inlet valve and used a Hornblasters electric valve to dump the air out. Customer loved the idea of it and very pleased with clean install. Hornblasters customer service was very helpful. I used the Live Chat a couple of times before and after of the purchase. "Tyler" was very helpful and knowledgeable on the hornblasters products. Will definitely use hornblasters products in future for all my air suspension parts!! And prices are reasonable.
