The bags have internal bump stops, I'm not sure how soft they are, but it's not quite even touching the shock bump stops yet.

Well after a long chat with Ryan at Accutune, I am going to try to raise the front end up 1" or so and see how that goes. I may be bottoming on the bumpstops in the bags. Unfortunately this will increase spring rate.... Going to throw a zip tie on the shock shaft too. And Ill dump it again and measure what I have for minimum shaft length just to compare to. In theory the zip tie shouldn't get to that measurement.

That's not a bad thing necessarily. Your original issue could have been that you were simply bottoming out. Most of us would be able to recognize that I think, and that's why I didn't think to mention that.

Could also put a go-pro in your wheel well and record suspension movement while driving. That's always a neat trick, and will show you how much everything compresses when you experience your symptom. That might be a better next step.

Yeah it will be more than the kelderman spec, but worth a shot.

Rear is going to need a lift if the front goes up more....

I have never used bags with the internal bump. It makes me nervous not being able to see them or change them out if I don't like them. Starting to think my paranoia was actually correct.

You said the shocks were his issue before. He bought fancy shocks with different valving per your recommendation and the issue is still there.

Or were you suggesting something else?

Not just his Suggestion FWIW.... But I think we may be onto something.... I don't think I will have time to do more than a speed bump test this weekend tho.

For the issues he was describing, a valvable shock is the only way to go. Something off the shelf that you can't change the valving will never accomplish what he needs. The whole internal bumpstop deal is a whole different ball of wax.

Sooo I'm pretty sure my Windshield is leaking.... Every time it rains I get loud "static pops" thru the stereo, even when it's off.....

Anyone familiar with these? Should I try to pull the trim and smear some goop on it or just take it to the pros?

From shocks one day to popping stereo the next, you are definitely covering all bases?

Good luck

It's done it a few times before..... But it's raining again and does it just about every time now..... Ugh. Scares the shit out of the dog when it does it in the middle of the night. Nothing like a 100lb scared German Shepard jumping in your bed....

Shocks and windshield could be domino effect.

If you have full coverage insurance a windshield is probably covered with a crack or chips.

It's been doing this awhile, just reminded of it now that's its been raining again....

There is a chip, but otherwise good. I'll call the local glass place for a remove and reseal/install quote

If you have glass coverage a rock thrown up by the vehicle in front of you while driving down a gravel road would make it so that it was covered by insurance...

Just thinking to myself and out loud I guess.

If I need more height in the bags, and don't want lift why not just trim the lower bag mount down an inch? I'm assuming the bags will be Ok higher.

Probably not all that hard to unbolt them, cut them down and reweld. They are the ones with the angled plate.

Thinking some more..... Then the shock will be the bumpstop. Ugh unless I can perfectly predict the internal bump stop and have them both hit at the same time

Cant u just put the bag in a vice or step on it and measure what its minimum height can be and then go from there? Is there enough room for an external bump? Can u raise the upper shock mount assuming it cant go to full extension now?

I can dump the air just like I did, truck is a big vise

External stop would be a PITA.

If I need shorter shocks I will work with Accutune to get them.... I gave them the measurement from the lower bolt to the mount with the bags at 8" tall.... But yes and no... There is a LOT of shit right above the shock mount, but it could be done. Lower might be easier to drop!

Spring rates.... Needs to be high enough to hold the weight. Unless I'm crazy I can't get any less?

Added zip Ties to the shock shaft. Definately not bottoming on the bags bump stop. Only about 2.5" of movement on the uptravel anyway.

And.... My oil leak is getting worse! Grrrr no idea where it's coming from now. Looks like rear main ish as the most of it is around the back of the oil pan and the bellhousing.

Upper pan doesn't look like it's leaking.

Underside is well oiled now...

Begin ramble...

Spring rates. you need a minimum to hold the weight up. No two ways around that. BUT with the air bags, you have to add pressure to get the height. A spring can be made taller at the same spring rate correct? Where in the air bag the spring rate is increased with air pressure. However in theory the spring rate is as low as it can be to hold the weight at X height?

Zip ties on the shock shafts show I am not using the front suspension. Nearly NOT AT ALL. When I got to the start of gravel, I hopped out, three fingers of movement on the shaft, ~2.5" uptravel.... Thats not much (and not bottoming out on the bags)

Here is after a pretty decently rough section. A bit more movement, but still not much...


I did try inflating the bags to 9" tall. No difference, a bit worse even perhaps (more spring rate...). And they sit funky on the bases like that, not happy looking.


Frustrated.

Should I go back to coils? Just try to find taller softer ones?! Anyone have an idea of spring rate needed? 6200lbs on the front axle.


Went and played on the rocks.





Shoved my phone in and took a bunch of pictures.... This one caught my eye once it was on the computer. Looks like possibly the dipstick (or whatever that tube is..)? There is no "gunk" stuck there, high flow spot?

So you're still having the same issue as before the new shocks, and the shocks, nor bags, are bottoming out when it happens, based on the zip tie trick?

As for the oil leak, holy shit that's a lot of oil. Is the dipstick connected in that picture? Looks like it's not.

Correct, nothing seems to be bottoming at all. I am using hardly any suspension travel

And yeah.... Its a ton more than it used to be!! Its always leaked a little, but not like that. I didn't even see the dipstick when I was under there.... Only in the pictures. I will have to clean up and investigate.

Its just a Oring and a retainer clip/tab it looks like. Oring shit the bed perhaps?

That oil "leak" is just Ford's way of keeping the frame from rusting.

How much pressure do you have in the bags now? What # are the bags?
