Expert Reply:

I do personally prefer Firestone air springs over Air Lift, but for your specific vehicle the Firestone kit available will limit your compatibility with in-bed hitches. I recommend going with the Air Lift LoadLifter 5000 Air Helper Springs # AL57288 so that you'll still be able to install and/or use an in-bed hitch. These springs have a 5,000lb capacity to help offset suspension sag and keep your ride height level.

If you plan on hauling different loads regularly and need to adjust your psi levels on the go then I recommend also picking up the Air Lift WirelessAIR Compressor System for Air Helper Springs # AL58WQ. This compressor comes with EZ-Mount brackets to avoid having to drill into the frame for a much easier installation. This dual path compressor can adjust the psi levels in the air springs separately to help deal with uneven loads in the bed. The included remote and Bluetooth connectivity will allow you to monitor and activate the compressor without having to run any lines into the cab like you would with other systems.
