Geoff Weeks Posted 2 hours ago Share Posted 2 hours ago Some trucks have left and right level valves. The heavy haul tractors one place I worked had their tractors set up like that. You had to make sure they both set exactly the same. This assumes that you have actually measured the pressure at the bags on left and right. Trucks with only one valve, well you only have one source feeding so they can't be getting different pressure from the valve.

Will Posted 1 hour ago Author Share Posted 1 hour ago Could it be a bad ride height valve? Quote Link to comment https://www.bigmacktrucks.com/topic/76516-neway-suspension/#findComment-593600 Share on other sites More sharing options...
Geoff Weeks Posted 49 minutes ago Share Posted 49 minutes ago not that I'm aware of. Take a picture of the valve in question. The ones I'm talking about have only 3 ports, inlet, outlet and exhaust.

Geoff Weeks Posted 48 minutes ago Share Posted 48 minutes ago Did you check for two valves? Did you check the pressure at right and left bags and confirm they are different?
