Bags in place of coils ? 68 Burban. What Bags

[72MARIO]

I see that ECE sells a air ride kit for trucks and burbs. I would like to put somthing like this in place of the rear coils. So I roll low and still tow a car trailer. I dont think I am going to notch it because I am worried about the strength.............. just put in a 1/2 bump stop on the frame.

I see that Air lift has a small compressor kit looks neat and small would it work oky ?

So what bags should I use besides the ECE kit ?

Panhard bar ?

I have looked at the KP kit with the notch and truck arm kit it looks really neat but would it still be as strong as a Factory frame ? I would love to go this route but I need to be able to tow.

the burb

[PBFAB.COM]

Once you swap over from coils to bags, I would recommend a trac-bar upgrade as well.

Are you planning on doing the front as well? or just the rear at this time?

[72MARIO]

I will do the front in time. I need to sell my 67 short box first.

[PBFAB.COM]

If you plan on doing the front at a later date, then you may want to hold off on an air management (compressor, valves, tank, etc.). You can run the rear on a schrader system that can be inflated with a shop compressor when it's time to tow, and left at "just the right height" when you're not.

do you know with the ece kit can i roll with it about a 5" drop and still have it ride nice ? are there any better options ?

[sixtyeightchevykid]

im thinking about doing the same with my 68 lwb, but im lost so any help would be good...

[gringoloco]

I would start with a 2600# bag of your choice. Slam Specialties RE7s are good stuff, as are Dominators and Firestones, but there are tons of choices out there.

There is a write-up in FAQ about how to convert from coils to bags without using any of the fancy, unnecessary mounting bracketry found in the aftermarket 'kits'.

The bolt-in notches have been found to be plenty strong for towing, especially if welded in for insurance. Many people on the board have done it, myself included. A button bump-stop would probably be sufficient at only 5" drop though.

Full length panhard bar, ala ECE or CPP will suit your needs, and are adjustable.

i dont want to seen like a dumb kid, but i cant seem to find the write-up... could i get a link?

And my intelligence is again questioned because I don't see a coil to bags thread in the Suspension and Steering FAQ section.

Here's a few air bag tech articles.
Plus a few other suspension articles of interest.
I'll add more when I find them.

That is an awesome list, and yet not a single thread from here.

My comment was more to the point that there are many great build threads with pictures that I used to be able to find but somehow can't and none of them are in the FAQ section. Hell, gringoloco's dropmember build was one that I can't find now.

Sorry,... I was trying to satisfy you guys until I got home.
I couldn't find the FAQ "coils to bags" specific article.
I don't even remember one.

I did my search on the internet in about 5 minutes with DSL at work.
I have dial-up at home.
So I won't be much help.

There are a bunch of member that want these threads.
I'll do some looking,... but you guys have to help me.

Better yet,... do a tech article of your own,...when you bag your own trucks.
See how much of a PITA that is.
That's why I commend people like Rokcrln,... that has the patience to do what he does.

I'll keep looking on here.
But the internet and Google is a great source also.

I like using a RE-7 or SS-7 Slam Specialties bag,... bolted directly in place of the coil spring.
Use a 3/8"x4" bolt with a HD washer thru the trailing arm.
Drill 2 mounting holes and 1 large air fitting hole in the frame, to mount the upper end of the bag.
Run two lines with two schraders for the time being.

[gringoloco]

Found it! It was under Krue's index thread...

MrShelley's guide shows the basics. Feel free to ask any questions you might still have after reading through it. I have done three trucks, my '70 and two friends '65-'66s, exactly like this with excellent results.

Good advice here. Crank snout/harmonic balancer washers work well for the long 3/8 bolts.

You can also use a cheap in-line ball valve so that you only have one schrader. Open when filling, so that the truck is level, then close to prevent side-to-side transfer, extreme body roll, and scary handling.

How did you find it?

[tech@scottshotrods]

we are doing slams SS7s under 75.00 with free shipping bracket kit for 70.00 (all four upper and lowers and have lines and fittings

Ok I see alot of diffirent bags out here. The ones the erly classics show are huge. What is a RE7 vs SS7. The bags look to basically bolt in. but what ones ?

I am going to need a super track bar kit. Is there a better option ?

SCOTI will your shock mount mod work here with some shorter shocks ?

The air line are pretty easy I undestand all that for now.

Yes. Prob won't even need shorter shocks, just OE replacement length.
