Custom front airbag suspension

[oldestof11]

Thanks Eric!

So it looks like I should be running near 70-90psi. I wonder if that affects the ride that much vs something at 50psi. I would think yes but is it better than cut coils...

[oldestof11]

After reading Jared's whole thread and doing some more research, I am thinking of going with Slam Specialties RE-8's. At 100psi (out of 200psi) and 11" of height (unnecessary) it'll hold 3526lbs. At 6" it is over 4000lbs.

2 of them I can get for $250. Not bad I don't think.

you will have a much sharper ride with the bags at 100psi vs 50psi , something else to look at it is if the bags have bump spots built in. bump stops in the the bag make it much nicer to drive home if you have problem vs towing it

this is a setup we are just finishing up, 10" travel with 11" wide bags.
I do have a hand up on some people i have a 4x4 cnc plasma table so brakcets are pretty easy

[oldestof11]

With this being a lowered 2wd, suspension travel is going to be below 10".

[winkdemon]

the joints we use a emf bush joints for on road setups , find heim joints of any kind dont last as long as we warranty are work

all of it. I have a question when your travel is at ride height are you axle and bags sitting straight?And when you rasie or lower your suspension does the axle move to the left and right?
Thanks
Chase

from bump stops to full height the axle moves 1/4 inch from side to side . bags are straight and axle has pinion angle set

[oldestof11]

So why use a pan hard instead of a watts link?

Jonathan,

Not sure if this will help.

That does help. I think I have the rear figured out. I was going to do like Dale (owns the 2wd puller Gambler, Ford with a Perkins swap. Can't remember his screen name) and cut the main leaf 10 or so inches from the center line of the rear axle, add a 2" square bar, and weld a plate on the back for the bag. Add a pan hard or watts link and it's a 2 link.

i like the pan hard bar > less work , less parts to wear out ,less money to build . on a lower truck that wasnt going to carry wait i would consider one just for the wow factor

Where do you get those numbers?

My rear bags take 11 psi to hold ride height on my dually. With a full tank of fuel.

[Str8jacket]

Im building a 2wd truck, total load capacity 5ton all up, using a chev c30 front subframe and building a torque arm rear. I emailed around and eventually decided on slam specialties ss7s for for, emailed them and that is what they recommended, said 8s would be abit "wallowy" for the want of a better made up word. The rear bags I am pretty sure are the sliding taper bags previously mentioned, not home so cant get part numbers. And I am also using the emf bushes mentioned as well. Havent built it yet but have all the parts here and am impressed with the quality of all of the so far. Hope that helps

On your dually you have leaf springs and air bags correct?

I'm talking front bags too. Rear bags would take less until you're loaded.

No leaf springs only air bags. I have full rear air ride. Radius arms. Winks first air ride set up.

Even with a couple thousand pounds in the bed I don't get anywhere near 70psi.
