 What's happening YouTube? Thanks for tuning back into the channel today. We've got something really special for you We've got a one-piece driveshaft conversion going on for the Duramax It's kind of put in conjunction with the Kodiak driveline the new transfer case that Mark over here is going to be rebuilding for us But we wanted to go one step further and be able to do a one-piece driveshaft for my LBZ As you know the quad cab long beds, they've got the annoying two-piece driveshaft and Two-piece driveshafts just in general are just more failure points more moving parts means more failure points They've got smaller u joints. They've got slip joints, so we're gonna be doing the upgrade today. Make sure you guys keep watching So here she is up on the rack again, and no nothing is broken Of course as I said before we are getting rid of that ugly two-piece driveshaft there we've got a nice one that we are gonna up fit and Make work for our application. I'll go through the details of that when we get to it So we got the old driveshaft out of here This is the old two-piece driveshaft here and then the new one-piece one that we picked up from GM This thing is monstrous guys I'm talking like we're we're a good two and a half inches wider in diameter And it's gonna be a lot lighter a full aluminum setup. This thing is a killer setup So we're gonna look through this one. It's gonna be slightly different on a length But we're gonna make up for it with our yoke and other setups here I think it'll turn out really good, and we'll see what we can do with it So we've got the bracket cut out that originally housed our center support bearing. That's now out So when when we were looking into doing this one-piece driveshaft in the first place What kind of measurements were we looking at in the difference between the stock unit and this new aluminum? Housing sure. So what we wanted to maintain is the slip yoke that came out of the back of the case We wanted somewhere around two to two and a half maybe three inches tops of The yoke hanging out the back we didn't we can't have the yoke all the way buried in So we basically measured from center of the U joint to center of the U joint on the factory shaft and determined that the one that we got from the L5P trucks and even the late LMLs will will definitely work So as far as when you're going to be ordering one of these one-piece driveshafts What are we looking to order? Yeah, you're looking to order from like a 2015 and newer four-door long bad newly and that's going to come with the one-piece driveshaft and everything now as far as So we're looking at the correct length now What is the other thing that we're going to have to swap over sure then you're not to swap your yoke over because all those Structs are in 1480 U joints So we've swapped the yoke over so we got the 1480 yoke now We use the GM yoke with a new pinion seal washer everything's locked tight it What are you ordering this one from? This comes straight from General Motors. What what your model you think you can order anything from a 1 to 7 with a ZF6 truck Transmission because they were all the manual transmissions had 1480 joints in them. So just with the larger U joints We're going same width and everything just larger U joint Availability to it so everything else is gonna match up perfectly to that everything on the front spline There at the transfer case. It's going to be all spline the exact same on that one. It's all going to match up correctly So let's get this thing slopped up in here, and we're going to see where we're actually looking at So he was looking at the only other thing you're going to have to look at ordering is the new straps for also the 1480 rear U joints as well We don't have to worry about it because there's a few parts around in this area He's got parts and parts and parts and parts and transfer cases and parts and parts. Yep, we're good to go So drive shaft all into place you can see out of our like roughly Six and a half to seven inch yoke. We've got about two and a half two and three-quarter inches hanging out which is fantastic with the actual Rear-end travel that we've got into it earlier on the other two-piece drive shaft We were having issues going through rear seals on the transfer case Because that rear drive shaft was actually hitting into that seal not going to have that issue anymore We jacked up the rear end and even with the rear end jacked up and the Suspension at full travel. We've still got three and a quarter to three and a half inches of yoke Actually engaged in spline so that is more than enough for what we're looking at and this thing is just a big old beast That is all Standard drive shaft there for you, but it's a bunch of sexy drive shaft So hopefully this kind of build is going to be something that you guys look into if you have a quad cab long bed L BZ Lly classic body style the sizes of this drive shaft is going to match up to what you need It's going to give you guys more dependability. It's going to be a lighter driveline in general Bigger you joints and just a better overall driveline in general So again, I will leave the link in the description down below to all of the stuff that I ended up using I'll try to find those in the part numbers through GM But if not again earlier in the video I said what they went to and you be able to go to GM and get a hold of them to be able to find any of those parts Thanks to Mark again over at Kodiak driveline for hooking us up and being able to get us some awesome footage today Make sure you stay tuned for more to come on this. Thanks. And as always you guys stay awesome You
