cutting down a drive shaft - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I know its possible but is it a good idea? is there a driveshaft that can be used for a crew cab short bed like a long bed extended can off 88+ or even 73-79 ferds? i was thinking of chopping out and chunk with a chop saw and having a buddy who is a pipe fitter weld it up.

Take it to a local drive line shop and tell them how much shorter you want it to be.

is that the place by the train station?

Driveshafts have to be right. They have to be balanced and they need to be exactly straight. Your buddy might be a great welder but pipe sits still. Driveshafts spin at engine rpm. If you ever saw a driveshaft break at speed you wouldnt be asking this question. Driveshaft work is relatively cheap. Last one we had built was guaranteed to 1200hp and with them supplying yokes and u joints was 300 bucks made from scratch.

I have had a local diesel shop build all of mine.I have had a few made none have failed and most i paid was 350 bucks.

Al you need is new tube,if it's longer,or cut and re-welded. When I have mine lengthened it has never cost as much as $200...shortening is about $100. It can be done inside of an hour.

Yes it is. They built the shaft on my 67 belvedere. And it had a trans brake and a 750hp stroker 440. That shaft took it like a champ

I always shorten my own. I cut them, put it together with the joints in phase, tack it back together, install it in the truck and spin it to get it dead on straight, and weld it up. never had one break, and my truck will twist up the frame when I get on it. but if you're not comfortable doing it def pay someone else that can.
