Tube Chassis Truck?

Not sure if this is where it goes, but since suspension brakes and steering are connected to it I figure it goes here. Sometime in the near future I'm wanting to build a custom truck. Engine/tranny swap, IRS out back, ect. I've seen a few old trucks like F100's with all tube frames, kind of like skateboards to sit the truck on. With the kind of stuff I want and the performance I'm going after, I decided on that tube frame. Anyone have any references to how to design such a frame for a truck? Most I've seen just seem to be basicly strait with tubing zigzagged between the two rails to make frame rails. I know there's alot more though. This is going to go under a 98 or so Ranger (extended cab if I can help it) btw. Thanks!

You should build a chassis jig using the original frame as a model for track width and wheel base. When you do your motor setup put the cab on so you can see if you'll have modify the firewall. I got the Chassis Engineering book by Doug Herbert and found a lot of useful info in there. Hope this helps.

If you really want chassis stiffness (especially in torsion) a "skateboard" is not what you want. You would want to incorporate a cage and tube chassis into one solid structure. If you don't go that route you might as well just box your frame and call it good. I have seen people make balsa wood scale models of the chassis that they intend to make to and test it by bending it in their hands or putting small weights on it. Because of what you are dealing with you might want to take a look at some same era trucks turned into desert racers. Most of them have very stiff chassis under their skins.

Well, it's still going to have a cage as well, I just really don't want bars sticking out of the back of the cab, unless they're under the bedcover. I figured I could drop the body over the chassis (I'm going to channel it substancually) then build a cage inside/through it, as it'll have some bars extending towards the front to further support the suspension. The chassis I looked at was basicly a box, a rectangular box, but a box none the less. I wish I could explain it.. maybe i can find a picture and post it.

Think it was the FR100 Concept truck with the 5.0 Cammer engine.

I meant to say Herb Adams wrote the Chassis Engineering book.

Alston also has a good book on drag chassis design. Be sure to get the SFI spec on how fast that truck might run so it can be certified. It will really increase the resale value of the truck, when the day comes to sell it.
SFI has the chassis specs for tubing size and lengths to build the cage from. A good chassis builder in your area will have a book giving all the sizes.

So you just guess? 180? This thing is gonna pretty much be a high reving supercar under a truck body. With what I'm thinking of doing I probably should invest in a few books on chassis building.
