Long Travel BS Thread

Awesome work by @906taco welding up new spindle gussets, coil bucket gussets, and installing new uniballs in all the control arms, as well as installing those hydro bumps up front. He also powder coated the arms and they look great. Don’t mind my crusty-ass coilover making everything ugly lol

 

Was a pleasure meeting and working for you! You’ve got the right vision to have a very potent build!

 

I used some 1.5 in a couple spots, like the intrusion bars. Curious if you'd be willing to share where and what thickness you used. I was going to do the floor structure out of thinner wall 1.5" tube, but make the structure below the drivetrain that the skid mounts to out of .120.

I'm guessing the back wall and center harness wall could all be thinner like .095? I was going to also do the back half structure from the back wall to the axle out of .120, but from there back, go to something thinner as it's not really structural anymore. I hadn't thought about tube thickness for the engine cage yet.

Would love some insights to keep the weight down on this thing

 

Bro just pull a gruppe b and make a PVC cage.

 

My whole outer main structure is 1.75x.120. Then I used a mix of .095, .083 and even some .063. It’s all going to come down to design that will dictate what you use where. Provided the main structure is .120 you can get away with some pretty thin stuff elsewhere.

Every single step of the way, you need to be focused on weight. Save it anywhere and everywhere. Ounces add up to pounds really quick.

 

For perspective on cage strength/design.

When I was doing NHRA legal cages the largest tube used was 1.625x.083. This was done for cars around 3200lbs crossing the line at 200+mph.

granted this was all 4130 it’s still small tube considering. I think thinnest used in these chassis was .049.

Bend as little as possible, miter as much as possible. But when you miter make sure you wall plate it.

 

got a scan of the 1gen spindle this weekend... design continues.

does anyone know the outer diameter of a 3.75 ID coil?

 

every racing org rule book ive looked at for offroad truck racing states you must have 2" .12 wall for anything over 4k lbs...... but i will say the way my truck is balanced if i moved the engine back i would end up even more ass heavy than i already am...

 

Play trucks and race trucks are way different.

 

Bingo. It wouldn’t still have frame rail if it were a race truck. Either way. Weight still needs to be a consideration with every build. And no race truck out there is ALL .120 wall. Main cage yes. The rest is open to interpretation.

And even so, getting @WormSquirts truck to a 4,000lb range isn’t out of the realm of possibilities if he’s willing to spend.

 

It would have 5ft of frame rails if it was a 1450 race truck! But I can't see 4000lbs happening without some serious effort. Maybe if I ditched 4wd, which isn't an option for me. 4500-5000lbs seems reasonable on my current course.

But either way, weight reduction where I can is something I definitely want to keep top of mind!

 

Cut entire inner structure out of the cab. Billet everything. Lightest wheel, tire, rotor package possible. Aluminum block. It’s plenty doable if you really wanted to.

 

I wonder how much my truck weighs right now.

 

All of it
The whole thing

Probably maxed out

 

Once Im "done" with changing stuff I want to take it to a cat scale and have it weighed. Really curoious too.

 

I’m not much over 5k. A couple years ago it was pushing 5900lbs. Feel like I could easily drop another 1,000 off if I really wanted. And who knows. That day may come. First I need to figure out what direction I plan to go with it. Full chassis, or build something that will actually have room like an OBS F-150.

 

Can anyone with a dmz kit show me your rear bump stop setup?
I currently have the total chaos bolt on style with a 2x2 bump and that's probably going to have to go.

 

Personally I’d leave it on and see where it lands when you cycle the leaf’s. If it doesn’t work get a new mounting method but 2x2 hydro bumps are fine with SUA

 

Thanks dude
