I drove three separate 5000 mile trips in about 10-15 days each trip on my bilstiens, very comfortable after driving 22-24 hours straight some days, i just pulled them off when i got my lift and got the old man emu coils and shocks for the front 882's since i have a winch bumper, and honestly i think i'm going to switch them out for some billies. I can get the part number for you if you want tomorrow, but the truck rode nice for those trips, the thing is though everyone's butt guage is a bit different alot of people with my set up like it, it's just a tad to harsh for some of the overland travels i do, i plan on doing round trip from seattle to tennessee next summer so will be doing something a bit different and adding some beefed sway bars.
My votes for the billies though
