boxing

[knuddy]

hi,it may have been asked before but here it goes.
has anyone boxed the chassis rails on the 73/87 c10s
longbeds? can it be done and what if any problems could
occur in stiffening the chassis from the twisting moment?
i mainly only use my truck on good roads and cart dirtbikes.
BTW.i have a longbed c10 which is getting a groundup
resto.

I am lost as to what you are asking here. So guess I do not have an answer for you.

What are you hoping to achieve by boxing the frame?  You will have to move everything (fuel lines, brake lines) that is inside the frame rails also.

I saw a guy take another frame rear sectionflip it over and swap sides sklid it into the trucks frame to make a box on a K 30 that was being built into a tow truck. It was alot of work, but it did stiffen the frame up.
I some times put a short peice of flat on the inside in the back by the bumper mount area of the frame to form a box. This area is prone to rust and I put a hitch on all my trucks if they don't allready have one. Just for a little extra strength.

I boxed mine, and seeing as I'm nowhere near finished, I can't say that it has helped. I will say that if I had my time back, I wouldn't have done it. (Creates way too much work as mentioned)

The reason I did it, is because there was substantial rust on my frame (SWB) and I replaced approx. a foot of the original channel. (Here's a case of a free truck being 3 times more work than need be...should have let it go) All the early street rods and pickups are done this way I figured I'd do the same.  I also created an X section from the trans back to the cab mount. to tie it all together.

I hope I don't live to regret it....

i don't see a need for boxing it unless it's a full on drag truck.

my truck is giong to be 2x4 tubing from the firewall back, but that's only because my frame was twisted and i'm young and stupid

ok guys,seems like it may be a bit more involved than i thought,so ill give it a miss.the reason i asked ,is when you look at the chassis of those jappo pickups/suv they have a
boxed chassis rails and are stiff laterally ,so there is very little movement in the body/bed when going over uneven
surfaced roads, not offroad.that was the result i wanted to
achieve. my chassis and cab is rust free and is in good nick the cab mounts are all good .
this is my first truck project,so quite a bit to learn.(all good)
anyway thanks all.
