As the expo build progresses, I've gotten successively heavier and my suspension just wasn't up to the task. I had 850Js with a 1" spacer up front and 421 comps in the rear and was bottoming out freaquently on the trail and suffering from substantial body roll. Occasisonally the body roll was scary. After a conversation with Kurt at cruiseroutfitters, I decided to go with 418 comps for the front and 864s for the rear.
Huge improvement! the 418s are the same length as the 850Js, but much stiffer. I gained an inch of lift even though I'm not using the spacers anymore which means I gained 2" over the 850J. I now have about 3" of lift in the front - that was my target number.
The rear gained 2" with the 864s, though it still doesn't sit level when I'm fully loaded with fuel and water, etc. I installed Airlift airbags (which prevented bottoming out) but they were too short for the lift and so they weren't able to raise the truck to sit level. So, I have a set of longer airbags coming in the mail in a couple of days which should solve that problem according to Airlift tech support. That part number is 60755 for 10.5" long airbags (vs 8.5" for stock) for anyone with a lifted truck who is considering airbags. They also offer a 9.5" bag.
For anyone who has a HEAVY rig, I highly recommend this setup. Road handling is superb and won't rattle your guts. On a trail test in Anza with 5 adults in the car and full fuel and water, I never bottomed out (thanks in part to the airbags) so I think I achieved my goal of on and off road comfort from the same suspension.
