I recently swapped out my shocks on my 2018 Ram 2500 with Bilstiens 4600. Nice difference. Took the jitters out.
Going from a 1/2 ton to a 3/4+ ton is part of the problem. 1/2 tons are definitely more cushy in the ride department.
Only problem with airing down below the TPMS is if you're getting a flat you won't know it. BTDT. About 3 weeks ago while out camping the DW and I got in the truck to go to Sisters (10 miles) and the tire symbol was blinking. Scrolled thru the EVIC and sure enough the right rear was at 65 PSI. Got out and checked the RR tire and saw a screw in it. 1st stop was Les Scwhab.
