Re: Driveshaft
Sure it will, if you modify your crosser and order a custom shaft.
I'm putting in a single piece shaft. Custom made through Summit, 4 inch aluminum. ![]() |

Re: Driveshaft
What mods do you have to do to the crosser?

Re: Driveshaft
Make the hoop that the driveshaft passes through bigger, the driveshaft will hit the bottom of the hoop otherwise.
you could probably do fine with a 2 piece shaft, however I installed a new engine and tranny etc. and required a new shaft anyways so I went with a single. This shaft is rated @ over 500 RWHP |

Re: Driveshaft
You guys were scaring me. The PO installed a one piece (not that he took short cuts or did stuff 1/2 @$%ED). My friend has a one piece on his '72 C20. I just got mine tuned up. What are the advantages/disadvantages. I've got others projects in front of it; so I have lot's of time to read the pros and cons.

Re: Driveshaft
there is no real good reason to do this. The 2 piece is stronger than your average one piece, and it is WAY cheaper to build your 2 piece with top of the line parts, then it would be to properly do a one piece.

Re: Driveshaft
Seems like there would be a lot of opertunity for lost power on a two piece. I could be wrong but that's just the way it seems

Re: Driveshaft
All things being equal for a STOCK truck this is probably true but many of us have highly modified trucks. HandsomeRob is running the same big block I do with a longer than stock trans. I don't know how far he moved his rear trans mount but mine moved almost 12 inches....leaving me with a driveshaft about 39 inches long on an SWB Stepside. Not much sense running a two piece when the span is that short.

Re: Driveshaft
where will it go?
The resistance in a single added U joint and carrier bearing is so minimal its moot. If your engine is so lame that the added resistance reduces the rear wheel power levels, then you have some seriouse other issues. |

Re: Driveshaft
This is an article that might square things up for everyone, it's about cars but the same applies to trucks.
like I said I used a single shaft but I changed engine and tranny, and the the stock shaft was to long and had the wrong style yoke, also for this aplication the single shaft will give the right feel for hard launches. http://www.rodandcustommagazine.com/...ech/index.html |

Re: Driveshaft
The biggest problem will be you will stress the out put bearing to look like a egg on the tail of your transmission with a one pc shaft in about 100 miles!
Two pc design is much better.

Re: Driveshaft
Won't have an issue if both yokes are the same angle, issues arise when the tranny yoke and pinion yoke aren't the same angle, they should be parallel.

Re: Driveshaft
Sounds like more work than it's worth.
The weight of the one pc shaft is the issue, not the alignment if using a steel shaft. How much did that Aluminum shaft cost? What are you gaining by doing this? A 2 pc shaft takes care of all of that.

I'm gaining a shaft that will handle 500 + RWHP which I require, I'm loosing some weight off the rotating assembly and I was able to upgrade to stronger yokes, and U-joints. there is a method to the madness. Might not be the right choice for you but it is for me. And in responce to the original post, Yes you can use a one piece shaft. |

Re: Driveshaft
no LWB trucks 67 - 72 had a one piece shaft.
The shorter shats are less prone to twisting. shorter shafts are less prone to twisting the added joint adds a point to flex, a spot where you can take the shaft from one angle, and add another angle in it. Straight out from the trans (not perfectly straight, but fairly straight) and then to the cross member, where it can drop from that U joint. With this set up, the crossmember on the frame, where the C bearing is mounted, can do its job adding rigidity to the frame. If the hole is large, it isn't as strong. In order to cycle the rear suspention from full drop to full compression, (as a working truck) the hole would be too big to add strength. However, small hole in the crossmember, stronger frame, U joint right after that, full range of motion on the rear suspention. |
