If nothing else, after putting a thou mi or so on it, might be worthwhile to check the rear pads to see if they're showing any wear. If yes, then probably all just fine. Overall, how do you like your disk/disk system? How long have you had it?

crackarjax - while I understand what you're saying, I'd personally use a disk/disk mc for a disk setup if, for no other reason, than to have the correct dia piston pushing the fluid (and in the correct size lines). Otherwise, pedal effort starts to get monkeyed with.
Nope I left the hard lines as is except from the rear tee over to each rear wheels.
They are working because when the valve popped the rear where the only thing stopping the truck. I've had them on the truck over a year now. I just put over 700 miles on the truck this weekend alone.
I can't tell you I love it other than the looks! As far as stopping power the 11" drums stopped it just as good in my opinion. Maybe in the rain it stops better now but over all I was disappointed in it. I really thought I was going to see a big difference but it hasn't happened.
For the money spent on the kit I wouldn't do it again!

Get out and drive the truck this summer and have some fun!
It sucks not being able to hear!

LWB trucks rule, if you don't think so measure your SWB!
After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.
