do rockers give any structure?

[CRASH]

Crash, did you put anything in the space between the rocker and the rest of the body? What bent? The rocker? I'm halfway done with drawing up my contoured rockers. I was thinking of using 3/16 but I'm going to stuff the inside with some sort of plastic to keep the rocker from crushing.

I have a pic but for some reason we can't post attachments.

I didn't "stuff" anything inside there.

What do you plan on stuffing in there? I think my grandma's fruitcake batter would be awesome.

You might even get away with running just that and forgetting about the 1/4" plate.

I ran mine for 5 years. They are bent upward aboiut 1.5" in the middle now.

It would hold up but why bother. atleast with the tubing you can make nerfs out of it and keep trees and such off your doors, but thats just my thinking.

Crash, I thinking nylon 6/ or what ever I cna get for cheap. The ends one either side of the door will be caped and more or less boxed in. I figure the plastic would keep the rocker from crushing in and spread the load along the inside of the body. I'll also have tube running along the magority of the length to use as pivot points,ect.

You also need some support behind whatever you put in there, I originally had my rectangle welded to the top and bottom but it did not back up to the inside. The rockrail eventually bashed in and would tip up. I now have supports behind it and the tie ins to the pseudo frame rail similar to the ones pictured above from the urf racing garage.

From personal experiance I would not replace the rockrails with anything unless they braced up along the inside to where the body makes a 90 degree up from the floorboards and to have the frame rail tie ins.

This is coming from a been there, done that, didn't work, and was a pain to fix right the second time type of perspective

If you are replacing them with steel plate in the same plan as the original material, I do not see a problem. If this is not your intention, post some specifics and i am sure you will get additional information.

FWIW - I used 2X1/4 pipe, go pipe or stay home.

Does a high lift jack do as well on pipe as it does more of a box? How about a square rotated 45 so that a corner was the surface that meets the jack?

Some more drawings, some with the T&J Chassis stiffener, but with or without that doesn't matter. Comments on these designs?

This one doesn't seem that strong to me.

This design seems like it would work pretty good, I'd probably have 3 or 4 legs from the frame rail to the rocker tube.

Seems like this one would work good too but allow you to weld the floor pan to the arms if you wanted to, making it more of a unibody structure (maybe?)

For numbers 2 and 3 to work the most effectively, they need to be attached to a cage, and 3 to 4 kickers.

#3 would never weld to the floor properly without a lot of floor modification....have you ever looked closely at how many twists, turns and kinks there are in an XJ floor pan?

Take this pic and take out the rectangle tubing and raise the braces to where they end just below the door line and cover with steel plate. Do you understand? Its really hard to freakin explain

is it me or is that the triangle braces on the above picture would get hanged up on the rocks? Could ya weld another triangle so that the pointy end goes towards the motor and butt it it up to the existing triangle braces so you would be able to slide over the rocks when wheeling. Just my 2 cents. :viking:

 

[JCSXJ]

Why did it delete the pic? It was up there before.

 

[CRASH]

There is a titanium plate going across the two existing + one to-be-added kickers.

[JCSXJ]

Let's try again.

 

[xj92]

One downside to that one would be no hi-lift points, another would be having to heavily modify the box tubing rather than just using it, otherwise would be cool.

 

[JCSXJ]

This is pissing me off! Why does it work for a minute and then show up as a red X?

 

[BrettM]

okay CRASH, you mentioned Ti, you can't do that and NOT expect to get some questioning :laugh3:

how thick? how much $? bolted on?

most importantly, WHY? it doesn't look like you're going ALL out for weight savings, and under the rockers is a pretty good place to have extra weight if you got to have it somewhere

Is titanium Trail Rated?

Structural foam Just squirt it in there

how much shipped to 95624, and does it come with URF stickers to put on my rig?

I just hit the U.S. Navy Submarine Pick and Pull yard in Bethesda, Maryland last week.

I'm all stocked up on previously owned 6v-4Al ti plate.

The only thing wrong with it is a light glow when the lights go out. I just can't figure out what that is all about??? :wow:

What the heck, I got a good deal on it!
