Build 05 2500 SAS, The Red Rocket

wanted to get the opinion of the group here. is a ruff stuff 48" trailing arm kit going to be strong enough for this pig? it seems to fit the bill pretty well as far as packaging is concerned. I've been looking all over the place for the last couple weeks, and I have convinced myself that they are the ticket for my application. one thing I'm hung up on is that I already have a full set of the DuraFlex joints and I would like to use them if possible. that eliminates any of the kits that use whatever method of anti wobble when the shock mount center line is above the center line of the link.
 
another outlandish Idea i have is a poor boy cantilever setup out back but that one is probably overly complex and just a dream. It would be cool if I could use superduty unit bearings as the pivot points and run a 35 spline sway bar between them. even if it ended up as a 1:1 motion ratio, it would preserve quite a bit of bed space

high motion ratio (aka cantilever) will be problematic if you just have a coil over.

a trailing arm with a low motion ratio is better. there are ways to keep bed space especially if you are going to tuck the tire almost against the cab.

what about these?
 
Mockup lower links are in while I wait for my trailing arms from Barnes4wd, 48” on the dot. Struggling to decide on upper link length and frame side placement. I put some 36” uppers in there to eyeball it but haven’t decided totally what i want to do. Any input on upper length length and frame side vertical separation is appreciated

Yesterday I tacked up the TMR fuel cell mount but I stopped there because I’m still waiting for the tank to show up.

Started the Barnes4wd trailing arms today. Got 1 totally done. And the primer is drying.I was able to squeeze in the Metal cloak joint like I had planned. They ended up 48-3/8” which is perfect. I’m going to try and get the other done this weekend

Took me longer than expected but there was a ton of welding and then clean up grinding and sanding involved.
 
Spent my last day off getting the trailing arms finished up and bolted on. Built a couple pieces of plate to get the upper links in. Had to wait for some better axle side upper mounts I got from Barnes. Here’s a couple mockup pics. Not much progress but some is better than none. I ended up with 8.75” of vertical separation in the top hole and a 42” long upper link. 37* of triangulation which I think will be sufficient.

Shock clearance with the frame will be a little bit tight but I believe it will work out. Even if I have to notch the frame for a tower it won’t be that big of a deal. I’m dangerously close to hacking the frame off at the cab and building my own anyway. Still waiting on the fuel cell to show up. Trying to decide if I should mount it against the cab or if it should go behind the axle below the bed. I’m kind of worried about dragging it on everything since it will hang down 6” from the frame bottom.
 
solid progress 🤘🏽

chop frame, cell behind cab if you dont plan on trying to go fast

slide the wheel base back a touch so
you can get a coil over behind the cab without it touching.
 
I guess I should have mentioned that I'm only running a single shock in the rear most hole of the arms. I don't think I will ever go the speeds in this thing that would require a bypass
 
Ordered up a set of 2" bumps from carbon_shocks. I hope they arrive sometime in the next 2 weeks so i can get the mockup part of the 4-link done and cycle it to see if I'm going to have to build a frame or not. I got notification today that the fuel cell and fill plate shipped. I'm pretty excited to start placing that stuff. feels good to finally be knocking some major stuff off the list. shocks and driveshaft are the next big things to order. who is everyone ordering driveshafts from now? my front is a 1410 CV from High angle driveline. I gathered that Jess closed up shop and I wasn't very happy with the buying experience anyway.
 
Off the wall question but could you measure the distance between the dust shield and the rear rotor? I’m welding brackets on my axle for a disc swap and trying to figure out how far the rotors should slide over the parking brake assembly. Slick build too
