Thanks for the feedback [MENTION=31274]corey_lax[/MENTION], it was informative posts from users such as yourself that turned me on to airbags in the first place. I remember reading a couple posts from [MENTION=80845]jerrybizzle[/MENTION] and [MENTION=56721]ScrewdFX4[/MENTION] where they said you could raise the rear a little while unloaded without compromising ride quality too much.
Truth be told, I was planning to install airbags at the same time as my front level. I have been saving for front level, airbags, wheels and tires since I purchased the truck. I bought the front level a while ago and recently had to get the front end aligned so figured I might as well do the level now to save having to do the alignment again after installing the spacers. The tires I had on the truck were toast so I picked up some used tires to tide me over until I can get the wheels and tires I want. Between the tires and the alignment it has left me short in the funds department.
I was looking at doing the blocks or shackle as I thought it would be less expensive, but blocks are going to be close to $200 anyway. Shackles would be much less expensive but I am having a difficult time sourcing them up here in Canada. I wanted to do Firestone airbags but there is a $50 rebate for the Airlifts right now so they would be $150 cheaper, that would bring them close to the price of the blocks. I will have to seriously consider that!
Do you notice any difference in ride with the 10-12psi in the bags? I would also be curious if you notice any more spring chatter while going over bumps, especially washboard breaking bumps.
