I had those. For a while.
Nothing but probs. PitA!
My install? Driving 'habits'? Poorly designed band-aid cure? Whatever.
Found that those bottom brackets that just sit in place on the spring via air pressure, would walk back-n-forth on the top of the spring. As much as an inch in either direction from their proper positioning, as per the instructions. I referred back to those numerous times trying to figure what I'd done wrong.
They require minimum 5lbs. of pressure at all times. I had to run at least 10psi to keep them in the 'right' place. ...and even then, I could see that they would still shuffle around.
Shot of black paint. Drive. Check for rub marks.
The problem? @ 10psi the truck was sitting at a 5" drop.
Nooo. Wrong. I lowered it 6, not 5!
So, as hard as it was to do, I dealt with it by gritting my teeth, putting the OCD on hold as best I could and resigning to "they are what they are."
I only needed them for carrying real weight occasionally anyways.
Ran them @ 5psi for a few months.
Then...I needed them. Two complete '50's Buick interiors in the box.
One front seat alone is over 200lbs.
On the bump stops.
But yea. I got this! Helper bags! Woohoo.
Through some air at 'em & all I hear is 'pssssssss...' from the right rear.
That bag had been walking back-n-forth so much, so often that the metal band at the top of the bag had worn a hole it.
A tire patch didn't work.
Now I gotta unload 1/2 this ****. Make 2 round trips. 80 miles each.
...and because I had dicked around trying to patch it, no warranty.
"Lower your truck!" they said!
I dunno. I think that maybe the prob has to do with where that top bracket is mounted on the frame & the way that the spring changes shape as it flexes through it's cycles & where the bottom bracket sits.
Having to be on an angle doesn't help things either. Maybe if that top mount utilized a pivot/shaft such as a shock's.
But, more-n-likely though, it was probably a reflection back on me & the corner-carvin'. HeHe. oops.
Some stuff just won't put up with me.
If something has a weak point, or a limit, sooner or later I'll find it.
More parts for the been-there-done-that pile
One thing's for sure, I found the weight limit of a 4/6 dropped RCSB 400.
To me, this makes more sense.
Vertically mounted, middle of the spring.
