valves

would this be a good setup?

soory the top two being dumps and the one on the bottom is a fill!!

i would go with a dump valve and a fill valve for each corner. so 8 for a whole truck

i had thought about somethign like that one day. and for the price of the 2 check valves, you have bought another valve and plumbed it alot easier

well how much are check valves? compared to valves?

yeah but in the event one side is heavier than the other, it may not fill straight and sit crooked. You have no way of fine tune adjusting on the fill other than dumping the one side back to match. Also if one corner develops somewhat of a leak, you can't just bump up the one corner.

just a few other things to consider. You're only cutting 2 valves from an 8 valve system which is going to save you less than 100 bucks while adding more joints causing more points for potential air leaks.

check valves are going to run you $20-$25 each.

could someone please post a similar diagram for a two 4 valve system for the front suspension i only have 4 valves and 2 bags to do the front of my toy.

if you have 4 valves for the front of the truck, i dont see the problem

in that drawing it shows you using 3 valves, run all 4 with one fill for each bag and one dump for each bag

If you take out each of those dump valves, and take out each of those check valves you can use one fill valve to fill both bags and put a "T" fitting on the fill line between the valve and the bags with a second valve to dump the two bags. This way you can use only 4 valves all together and have front up/down & back up/down.
