    Hi Everybody,
    I have a spread axle flatbed trailer and I am going to dump install a dump valve. Should I install it in the front axle or the rear axle. Which would be better? Can use some helpful advise.

    Thanks,

    rear axle...and wire it into your cab (use a spare toggle...and wire in a light to remind you thats it dumped)

    dump on every corner more than about 30 degree's.....it will save your tires and keep you from bending an axle

    just make sure to re-inflate or you will bend the other axle

    and if you are dumping....go slow

    If you're going to put one one might as well spend the extra coin and get a 2nd one on the rear axle too, there are some different angles in the roads, for instance like coming down a slight incline and making a turn at the very bottom, the front axle will be in the air so if you dump the rear all you end up doing is dragging the front and rear axles. Bronc is right about the light, you dont know how many times im haulin down these 55mph roads empty and all of a sudden i got a big blue cloud behind me because one axle wasent aired up.... As soon as you touch your brakes it will lock.

    Question? What kind of trailer do you have? Aluminum or steel and what make? What kind of suspension do you have also?

    Having a dump valve on your trailer is a good thing to have as long as you don't use it for every turn you make. You only really need it if its a super hard turn or if you get into somewhere and you have to make a u-turn.

    If you can put one on both axles.

    Dump the rear axle. We had one on our old flat. But when we upgraded there wasn't one. We totally miss it. It helps out so much when you're backing into a tight spot. We had ours wired into the cab so the wiring is still there. We just need to wire/install it on the trailer.

    Dump valves are handy in a tight situation. It's just when you have people who abuse them is when they become troublesome!

    Was by chance the new trailer you bought an East?

    A dump valve is for releasing air out of airbags on an axle. You can put them on any airride but are mainly used on spread axles.
