Hey Mike, welcome back! Both the Firestone Ride-Rite # F2613 rated for 5,000 lbs, and the Firestone Ride-Rite Red Label # F2709 rated for 7,500 lbs will keep you at factory ride height when you aren't towing. All you need to do is run the air bags at the minimum 5 psi.

In most cases, the 5,000 lb load leveling capacity is plenty. Your pin weight won't come close and most people typically aren't hauling so much that they need the higher capacity. Both sets of air bags are compatible with the OEM prep package like we discussed before so that won't be an issue.

Are you planning on installing an air compressor as well?

What about Pacbrake pv25rv . I can run it at 0 psi correct. That is one I am considering. Or is Firestone better.

@MikeH you can only run them at 0 psi because of the jounce bumper, which you're probably going to feel if you're running them like that. It is a 5 psi minimum For Firestone but you won't notice they're on there like that. Pacbrake as that OEM prep restriction you pointed out before, and Firestone is better anyway so I would stick with them.

@MikeH I agree with Robin. I've installed several Firestone bags on my trucks.
