Looking for recommendations for an air bag kit to be used with 4 inch lift pro comp 22415 springs. Also what length u-bolts for rear with these springs? Rear center of axle to fender measures at 27.5 and would like to stay around the same height. Currently have factory springs with aftermarket blocks and half a helper spring that previous owner installed. I do not have the factory jounce to install bags onto.

 

I used the PMF airbag tang plates. They're great. I can't remember what airbags I went with, think it was Firestone. I'll have to look it up. I would also definitely buy the Daystar airbag cradles. I've had much trouble with my airbags staying in place on the bottom so I picked up the cradles, just haven't found the time to install. But I expect them to solve my issue nicely.

 

I just dug up my records - I used the Firestone ride rite kit. And if you are doing the pirate pro comp recipe the rear ubolts I used were 8 inch.

 

Where can I find the pirate pro comp setup or list of parts? I have the 22415 and 22210 leaf springs on order along with shackles and spring hangers. I will get the top plates and cradles as well. I was hoping to find air bags and upper brackets separate but may just have to purchase complete kit. Being a heavy duty mechanic I have all the air line and fittings readily available.

 

Below are the parts I used. I just did this lift in March.

Front ubolts should be 9.5 length. I ordered 8.5 the first go around and they were too short. The rear ubolts are plenty long enough.

I used different shocks as well, but included the list for bilstein.

You can also find a cheaper adjustable track bar. I think most guys use on from Zone

I have this cheat sheet...Haven't made up my mind on which way to go

 

Neat spreadsheet, but do you not think you'll need u-bolts and shims for the X/C code spring swap too?

You have those part costs factored into the procomp lift, but not the code spring lift. Also the "rolling chassis" note at the bottom, just FYI model year 2008 is way different from the 05-07 truck front setup.
...

 

ATS includes U-Bolts, Shackles etc. in the price of that kit. Good pointer on the rolling chassis. I'll update it.

 

Firestone ride rites work great - I am running the same rear springs. I got some Daystar cradles which adds about an inch to the overall assembly. They allow the axle to droop a bit and most importantly don't stretch the bags which may cause damage. The bags themselves are most likely designed for the stretch, so I wouldn't consider them being required...
