Air line tee comment
October 1, 2011
By MeI am
"I see lots of people comment on the lack of a air line tee. If the bags are teed together you get more sway on curves because the air moves easily from one bag to another. If you want to inflate the bags evenly - use a TIRE GAUGE. One of the benefits of air bags is that you can compensate for uneven weights with different pressures."

Pros: Instructions were easy to follow. Took about 3-4 hours to install. Fairly easy.
Cons: I wish they had provided the required 6mm hex wrench. Not too many have these around
"I would buy again. I put them on a Dodge Ram 2500 4x4 with long bed. I have not yet used them with the camper a large camper. As easy as these were to put on I should have done so many years ago."

2005 silverado LS crew cab
July 24, 2011
By Rich
from Pa
Pros: easy to read instuctions
Cons: could not get the min. distance wanted only could get 7 in
"First of all it took me 4 hrs not 2 hrs to install. I could not get the recomended 7.25-9.00 in. of height on the bag. I only could get 7 in. The trounce bolt on my truck had a molded stud not a bolt so I had to cut the spacer block down a half in to get the nut back on.
On the right side of my truck the frame was stepped so i had to shim one side of the bracket about 1 in.
However after I got them installed they do work well. On the way home from my friends garage I did notice my truck did body roll in the turns. have hooked my camper up to the truck yet but I feel they will do just fine.
