^those are some sweet trucks!
I gave my new springs/air springs a work out today. This is with the 2" drop springs from tuftruck(advertised as 2", I got more like .5" to 1" drop). Also have the 9" long air lift 1000 air bags. I bought the spings used off another member. I bought air lift kit but with the drop they were too long so I got shorter air bags.
Roughly 2,250 lbs plus driver. Driver is a very dense 220lb
Yeah she's a squatting but it's also ~900lb over capacity and it rode great. The air bags really do a good job keeping it from swaying and bouncing around. It was sitting right to where the bump stops were touching. This was with ~35psi(max). I filled the bags AFTER loading, which is not correct, but I had no option.
And I swear my truck gets better mpg with a load in the bed...
