Using Firestone airbags with WD hitch?
First off, let me say that I have searched through the forums….and I’ve found some good info on this topic, but nothing really concrete. And a lot of the info I found was from way back in the early 2...

The two items will be working against each other! I would never recommend to someone to install airbags on a bumper pull. Install them for a 5th wheel since that weight is in the bed of the truck and you can level it with the bags. Bumper pulls use a wdh to, for the ease of explaining, balance the load between the front tires and the back. For your small trailer you could just use airbags or wdh but not both. If I had to choose one it would be a wdh and zero out the bags.
How do the airbags work against the WD hitch? Don't the air bags in effect just increase your rear spring rate? How does that counteract the WD hitch?
When you raise the rear of the truck with the air bags it does indeed change the effect of the hitch. Raising the rear with bags will reduce the amount of weight transferred to the front axle.
Best thing. Go to a level place. Raise the ball off the hitch. Air up to the PSI you want. Measure the front bumper distance from the ground. Drop the TT back onto the ball. Measure again. attach the bars, and adjust adjust the hitch until you have returned at least 1/2 of the raised distance back down. example. IF the front bumper is 15 inches off the ground unhooked, and when you drop the ball on the hitch it raises to 17" You would want the bumper to drop back down to at least 16" to the ground. 15 1/2 would be good, 16 1/2 not so good.
Now. Here is the kicker. Be sure you don't raise the rear higher than it was unhooked But usually, IF you get the front right. The rear will take care of itself
