Recommended Helper Spring Option for 2019 GMC Sierra 2500 Towing Fifth Wheel

Question:

I need some helper springs for my 2019 GMC Sierra 2500 4x4. The back end of the truck sags when I pull my fifth wheel trailer.

I'd recommend an air helper spring system like the Firestone Ride-Rite # F2613. The beauty of an air system versus a jounce bumper type system like the Timbren Aeon springs you've looked at is that you can specifically tailor the support provided by the springs according to the amount of cargo or fifth wheel pin weight you're dealing with. If you were to add a compressor system like # F2097 would allow you to add or release air from the system with just a flip of a rocker switch that you install in the truck cab which is extremely convenient.

With a fully adjustable system, you can dial in your suspension for fifth wheel towing, receiver hitch towing or even hauling heavy cargo in the truck bed, where with a jounce bumper type spring there is no capability for adjustment whatsoever.

I've linked to some installation videos for you, showing how the springs are installed and a typical compressor install.
