Also, I like your wheel and tire choices. I ordered up the same size tire and wheels. How do you like the Toyo A/T 2s? I ordered up the A/Ts (they were about 200 dollars less.

I didn't really do anything to bleed the hydroboost system other than operate the brakes and steering while it was running.

The tires are pretty good. I have about 12k miles on the truck now and they're starting to show a little wear, but still lots of tread left. They're pretty quiet (at least compared to the engine). The traction in snow/mud is OK. I did have to put it into 4wd to get out of my driveway the other day, but that is probably more having to do with the fact that I have open diffs than the tires The wear may be attributed to my alignment. The alignment guy suggested I get some offset ball joints to help it out a little, but I didn't. We'll see how they hold up over the long run.

How many pounds of air do you have to put in to start lifting the truck?

Thanks,

I haven't really used the air ride (other than messing around) Normally I don't have any air pressure in them and just drive around on the regular springs. The air bag set up may have actually made it a little worse, because when I bolted it all together the bolts that hold the airbag bracket to the leaf springs compressed pulled the springs together, so they're acting more like 1 higher rate spring compared to the multileaf setup that would get stiffer as weight is added. Its not much of a difference if any, although I may back the nuts off a little on the air bag brackets to "help" with this.
