Rear airbag questions

Aloha everyone,
I have a question about rear airbag install.
My tundra has a 4” block on the rear which brings the space between the leaf spring and frame to 4 1/2ish”,not much for bags to sit and also have upward travel.is this an issue if I keep a little air in the bags at all times?.
Would 2”block and inflating bags to ride hight(5”)work better?.
I’m looking for towing support for my lifted truck,also to stop rocking front to back,and lastly squeeze a little lift out the setup when not loaded.
Any thoughts are appreciated.

 

You owe me a cheeseburger ! I just got off my ass and measured my bags for you ! Lol
I have a 6 inch lift and am currently using a 2 inch spacer, I measured the bags only and they are just like you measured 4 1/2ish. To answer your question I wouldn't put air in the bags to makeup for the lift, it will not give a good ride.. Based off of your current setup, installation of Riderites would work perfect without putting anymore than the recommended 5 psi. When you load up then put air in the bags.. Hope that makes sense

 

Thanks for the info and the cheeseburgers in the mail,hoping to have system installed soon I’ll update with pics.i have a airlift wireless one setup and daystar cradles custom lower bracket and using the stock top bumpstop plate to mount.

 

Here’s the lower mount,just a little adjustment then it’s welded together,going for 7/6 lift all together.
