Applying air regulator to rear air bags

why not just adjust the rod on the ride height controll valve? there should be a plate welded to the center the rear diff with a few differnt holes in it. try moving the rod down one hole and see how that is. are you just pulling an RV?

 

or go drive a spring-ride for a week, you'll be happy with the bags as they are...

 

It doesn't work that way, you can't regulate the air pressure to the air bags for a softer ride. The amount of air pressure in the bags is related to the weight of the truck and load. The air pressure in the bag is the exact amount needed to keep the suspension at that height. The more air you allow in, the more air pressure is inside the bag. As the air pressure increases the bag will expand because the pushing force is increasing until the leveling valve cuts off the air supply to the bag. If you were to lower the air pressure in the bag to get your comfy ride quality the suspension will start to drop and ride height valve will allow more in to get back to the proper height. There may be only about 12 psi in the air bags to keep the suspension up when bob-tailing. With a loaded trailer you may need 80 psi to keep the right height. Drop the pressure to 50 psi, now you have less force pushing up the suspension. I hate to tell you, but there is nothing you can do. If your truck is too rough you need to look at the cab suspension, that is what is supposed to be cushy. If you have a solid ride cab suspension, you have my full sympathy!

 

and if you lower the suspension much off factory spec you open up a world of hurt in repairs as it wears out U joints and the rear section of your transmission do to the improper drive line angles which also cause all kinds of vibrations

 

If your worried about the truck "beating up" the trailer just install a typical goose neck fifth wheel. I have seen some that have a air ride type suspension between the fifth wheel and frame mounts. As far as the regulator, like the others said it won't work right. I have experimented with regulators going to my drive axles for when I sled pull. But in my situation I'm dumping alot of air to them not draining.

 

I really don't think moving the hitch point is gonna make any real difference in ride (whether it be for you or the trailer). The trailer is light to begin with so its probably gonna bounce around more than a normal class 8 trailer.

 

The more you move forward the better the ride, but like he said it's so light it's not much differance, but there is less bounce in front of center than behind. just ride a bus with a long over hang.
