Post some pictures, the tire will have some deflection when they get bottomed out

Probably going to start by taking 4" off overall on the cab side of the fuel cell carrier and see where that gets me. Not sure if the angle I put the rear end at is "realistic" or even possible with a sway bar installed

 

[exp24]

Are you running a custom or prebuilt fuel cell?

 

[exp24]

Looks killer, I would add and least 2" from the rear of the diff to the chassis for it to "swing" up or down that will leave room for the diff oil cap and a skid plate.

Yes everything on the chassis is going to be custom.

All that clears, the back of the fuel cell indents inboard to clear around the diff as it cycles. May be hard to tell in these photos but it indents 2" inboard

Still not sure on how much articulation this truck will ever see, edited the fuel cell carrier a bit and ended up with just over 6" clearance with the suspension all in line. If it somehow contacts it still, may my bumpstops find mercy.

From the drawing, it looks like it is more likely to hit chassis than bump stops.

I took angle measurements a looong time when setting up 2ghetto for cyling. What I found was with a lot of angle the shocks will bottom out before the bump stops even contact the axle. This never happens in real life. I cant remember... but I swear its not as much angle as you would think. I want to say in the 30 range from memory. I can't go find pictures right now because my work firewall blocks the site with geofence.

With that said.. i dont feel like 5-6" is much space!!

Here is 30 degrees of angle. Don't know about you, but this does not look realistic

OK yea... like i said.. its less than you would think!!! I originally typed 20-30.... but then thought.. it's gotta be more than 20. I just checked photos. And just thought this too. What is max misalignment of the heim joints. Cant be more than that! lol

Pretty sure it never does either of these below: You can see how shock is totally bottomed out at 24 and bump isnt even close to hitting

I have pics at 18*

and 24*

Awesome thank you! Did you run a sway bar at all? And if so how much did that limit that articulation you were seeing?

Thankfully if you're that articulated the suspension isn't usually moving fast, so bumping the shock like that isn't too bad (especially with the foam shaft bumps). But it's for that reason that I like mounting my bumpstops as close to inline with the shocks as I can (within reason)



Flexed out. It actually goes more but I forgot the driver tire was still on in this picture, so that side could droop further

Guess my current thought is making a bad transition from one section to another and my rear end gets put into heavy articulation, even if only for a second. I’m looking at other trucks with wider rear ends and it doesn’t look like the clearance is any better than mine. Think I’m just going to do a full mock up of my rear end without a sway bar and see what components max out during articulation and at what angles.

 

[FasterNU]

I didnt have one at first on that truck. And it never did anything wonky.. except roll over. LOL. But it has one now. Definitely run one. It's a world of difference for cornering speed and confidence. (in my opinion of course.)

I can't tell you how much it changes the extreme angles you reach in real world application. It feels significant but I cant put it in numbers because I cant compress shit like that in my driveway/garage. A sway bar is really just a spring that leverages force downward on the opposite corner. I would cycle without one for sure for worst case scenarios.

In case you want an apples to tomatos comparison... I have about 8.5-9" from my bumps to tire bulge.

Rad thank you. Mocked up the rear a bit more on the computer and can see the issue where the shocks bottom out before the bumpstop even comes close to contacting. Hard to tell what the limiting factor would be for articulation other than the shocks at this point.
