help...

I ask a question:
"is it a tube chassis car?"

reply:
"its a full box frame"

Can someone explain to me what that means?
Thanks.

 

Sorry to reply when I don't know any better...but I think that means the frame is made of square-tube, rather than round tube...

Mainly, I posted this reply so it will show up on my User CP when someone comes on and gives us the correct response...I have always wondered what this meant, as well...

 

best of my knowledge what little i have is the tube chassis car is just that a chassis put together with tubing. there's different types of tubing depending on what you want to certify to. and it is built to fit the body. the boxed frame is basically rectangular steel used to make the chassis one piece, however a lot of the stock chassis is kept in use. course that is just off the top of my head.

 

I hope we can get a definitive answer.

I've always thought a tube chassis was completely built new, with tube and sometimes some channel, such as a Pro Stock or Pro Modified car. A boxed end car was a chassis where the frame was built like a rectangular box and the roll bar tubing added to that. My drag car would fit the this definition. The "frame" has been connected with subframes and the ends connected with channel and the 8-point cage added to that.

Man, I hope we get a definitive answer.

 

This refers to the main frame rail construction of the chassis. If the main rails are 2 X 3 (or similar configuration) the chassis is considered to be a "box frame". If the frame rail construction is 1 5/8" round tubing then it is considered to be a "tube chassis" car.

Other times you might hear "full box frame" is when referring to the late 60's Chevelle's (and similar chassis). They did not have "sub-frames". They had a complete frame rail from front to back.

 

That's what I was gonna say

 

Uh, huh, and Frank is the most handsome and sweetest man to have ever lived, too.

 

Hence, "Heavy Chevy".(?)

 

Enough with the round up secrets already

 

I really worry about those two.

 

No need to worry 'bout me. I'm a nutt case and as long as I make money, they won't lock me up.:bananaman

 

Doesn't apply to a Maverick due to the unibody design. But a boxed frame can also refer to an original channel type frame in which flat plate steel is welded to the open side to form a box. It increases strength and reduces twisting and flex.

 

Hey Hawkco, glad to see you have a funny bone. No insult intended by me, ever.

 

Like trucks maybe?

 

Yup that type of frame. Boxing is common on early 30's 40's street rods. Unless it is a big buck car and they just buy a complete new frame.
