E350 suspension

I recently bought a 2010 E350 that was converted by Advanced 4WD Systems by the previous owner. It has a 4” lift, leaf spring front with Bilstein 24-065283 shocks, unknown steering stabilizer, 315/70R17 tires (70 psi). The ride is pretty harsh, bottoms out more that is seems like it should, a bit “loose” at highway speeds. Anyone else have a similar setup and experience? Anything different shocks could help with? Does 70 psi seem right? Newbie to all this.

I run 45 psi on 305/65r18. Off road I run 25psi.
Not familiar with the Advanced conversion but I think they are quite decent. If the crossmember was not trimmed properly, the differential maybe hitting it.

Why are you running 70 PSI in them? What tires are you running? Are they E rated? Look at your door jamb and run what is suggested by the manufacturer. Just because the tire says Max inflation pressure 80 PSI doesnt mean you blow them up to the max pressure. My rig is an E-350 and it is also lifted, it has also ruined two steering boxes due to the steeper steering geometery.
