Airbags

[GuppyWN]

Put a pair of Firestone airbags on my Tundra today. Haven't seen this but seemed like a neat location to put the fill valves. My license plate has four holes. Two top and bottom. The top is for the screws that attach the plate to my truck. I put the fill valves in the bottom two. Clean, neat and you'd never know they were there unless you knew what you were looking at.

Thought I'd pass it along if anyone is planning on a Airbags in the future.

Been putting air shock/air bag valves there for years.Its the best place to hide them in plain site.

Other than on my old Hummer, the top two holes for the rear plate are where I have always installed the valves. Once installed they don't need removal unless you move to another state.

I installed airbags on my 07 Tundra, anybody have recommendations as to how much air pressure to use for a tongue wt. of about 1,000 pounds?

Did you take any measurements of stock height?

What I have always done, and probably others do something different....

I measure the stock height from the ground to the bottom of the hitch receiver tube.
Then when airbags installed, set them at the minimum of 5 psi and measure again. I have always been lucky and the minimum air pressure has taken me to within a 1/4 of an inch of the stock measurement. (On my 2015 it is only 1/16" off.)

Then, after the trailer is connected and vehicle ready to go, and I max out the load on the front bike hauler deck, I take another measurement and inflate the bags to the stock measurement.

In my case, with a tongue weight of around 550, with a fully loaded deck, I usually drop about 1.5 inches.

Firestone manual suggests 1 psi per 32lbs of weight

[f5moab]

Can't find that in my Firestone Ride-Rite Manual; the one I received says....

" For example, 50 psi of inflation pressure will support a load of 2500 lbs. per pair of air helper springs. FOR BEST RIDE use only enough air pressure in the air helper springs to level the vehicle when viewed from the side (front to rear). This amount will vary depending on the load, location of load, condition of existing suspension and personal preference."

Just purchased a Chevy 2500, Purchasing (5 weeks) an 8528RKWS 5th wheel whose pin weight dry is 1090. No idea how much additional pin weight will be added but do you think I will need air bags? Just budgeting.
