heres what i use
Vehicle Suspension Kits - Timbren Suspension Enhancement Systems
replaces the factory cushion.
ive installed these kits on about 10 1500 trucks with stf decks
they handle like a ferarri with 2 big quads on the deck after
hahahahahaah
but honestly it stops side to side sway and stops bounce in the rollers
The airbags will only displace each other if the air lines are tied in together, you should be running a seperate line to each bag with two seperate shrader valves, have them on a 2500HD, work great.
