Cutting/welding the frame...

Well I've been tossing around the idea, of buying a single cab long bed. 4x4, pad, and cutting the frame to allow for a shortbed, then cutting the frame on my current truck and lengthen it to allow me to swap beds...

Is this do-able? As long as its done right, maybe boxing in the frame around the cuts??

I'm looking to build a drag truck, and also make my truck a CcLb,..

long bed to short is one thing, but short bed to long sounds iffy. I wouldn't wanna tow much with the short bed conversion much less the LB conversion.

The shortbed conversion would be strictly a 1/4 mile truck, so no towing for it. The lb conversion would use the same piece of frame cut from the longbed, so I had the correct lengths, Then after welding it in, I would fully box in the frame a good 4 feet where the welded piece was.

What kind of welder are you going to use? Whatever the case may be you will need to make sure you get a good burn in which it sounds like you know. You going to use c channel to box the frame? Using c channel would definitely keep the frame from fatiguing but it still falls back to the welds. Keep me posted, I want to do the same thing to my little beater.

You might try talking to Gene Feldhans; he goes by the screen name of weweld on many of the forums. You can say he has done some frame modifications to a few racing trucks.

That's a fitting screen name.

I would not be doing the welding myself, I know "how" to weld, but I would never trust myself to doing something like that. But I have a buddy that is very experienced in welding, and knows a lot about boxing frames and such...


I just want to make sure it can withstand a 1000+ hp diesel...

It isn't necessary to box the frame. There have been a couple of conversions here on the org if you look around. Very cool to have a reg cab short bed SD.

I havent looked at my SD but my 2000 F150 the frame is actually rivited together right behind the bed. There is also a crossmember at that connection. Maybe its the same way on the SD. You could just bolt it back together what ever way you want... wouldnt hurt to run a bead at the connection also

i would be scared to do this. im sure you know a welder around your parts somewhere. people cut and extend tractor trailer frames all the time and they are good for 80,000lbs. that has to mean something. or bit the bullet and trailer it to a shop and have them weld it. i dont think you would have to box it. jut reinforce it with a plate on the outside maby 3 feet long areound the weld. but im not a pro welder by anymeans soo....
