I run mine about 45 to 50 PSI and this makes the truck stance just like stock. My pin wieght w/ hitch is about 1500-1600 lbs. This is loaded as camping and 5er is 8000#. Check out the suspension connection online and I recommend investing the $180 or so for the on board compressor if you don't already have it. Couldn't live w/o mine. Adjust as you go. And as stated above do not run more than 10psi while unloaded. It will handle funny.:cheers:xterraintx said:
