Air Bag recommendations ?

[danielzink]

I'm wanting to purchase and install a set of air bags for my F-250

I've installed B code springs on the rear as well as a 5" Block.

I've talked to a couple places.

When I did the RSK is when I also put in the Donohoe 5" block.

Truck was still a little rear saggy so I put in a 1" zero rate block (Add a Leafs, Zero Rate for 4x4 Suspensions from Offroad Design)

Which made it sit perfectly level.

They're asking me if the truck is lifted.

From what I've read - the stock F-250 block 2" - is this correct ?

That would put me at 4" lifted if my math is right (stock 2" gone...added a 5" <2" +3"> plus the 1" = 4")

Thanks, Dan

I have air bags but use them for towing/hauling purposes to level out the truck. If you want to use the bags to level the truck, I wouldn't. They'll make the truck harsher. I would get the proper block and not use the bags as a crutch.

But if you're dead set on the airbags, Firestone or Air Lift - can't go wrong with either one. Are you going to get a controller for the bags?

I need them for towing.

Truck sits level...just sags a little when loaded.

I mainly just looking for reassurance that my math was right.

Your OP makes no mention of towing.

I'm lost with your math. Do you have a 5" + 1" block?

Yes.

Donohoe (Icon Vehicle Dynamics) 5" block w/ bump stop.

Stock F-250 block is 2"...

So my assumption is that it's now considered lifted 3"

Then the 1" leveling block = 4" total lift.

I would say you have a lifted application.

What I did with B code springs and stock f250 block is install a Firestone 2071 air bag kit. The airbag included was too short, so I installed an air bag spacer, like those listed here https://www.truckspring.com/suspension-parts/spacer-kits-air-springs.aspx. You could do the same, and measure for the spacer that fits your application.

I look it at this way....
When you swapped the D60 in, you made the truck an "F350". A stock F350 has a 3-3/4" rear block, let's call it a 4" block. Your 5" block = 1" lift.

Once I sat down and thought about it...and realized it didn't matter one bit how big a block was installed...

I ordered a set of Firestone air springs and mounted them.

I'll start a separate thread with the install pics...

But I could've had 12" blocks installed and it wouldn't have mattered...

being as the airbags mount on top of the leafs...

Needless to say I didn't purchase my springs from the first company whose salesman insisted I purchase the additional 2" spacers for $70....

Air bags are mounted like this:
