Hey everyone, i have a 2005 extended cab long box with the zf6 and wanted to convert my 2 piece steel drive shaft to a one piece aluminum. any ideas where to get one?? i know you have to cut the center support plate off and change the yoke in the rear but i need to know were to get to the shaft or if it needs to be custom made. any ideas or help would be greatly appreciated

Thanks a lot:gearjamin

A good Driveshaft shop is the best. Look onLine-- or Yellow Pages.

Gm has a drive shaft that they were putting on Allison trucks with center bearing problems. That was the route I went, however, if I could take it all back I would have went custom built. That way you can keep the 1480 series joints and not mess with swapping the rear yoke.

Yeah that's what I was thinking just have a custom one made, I was going to get the kit from the duramax store but it's for a crew cab long box... so then I'd have to get it cut down and and that point I'll just get one made.... could I get a custom one made using the stock yoke though??

Yes, just tell them the length and what u joints you are using. You truck came stock with 1410 joints so thats all the driveshaft shop would need to know. The 2007+ trucks use a bigger 1480. I swapped mine out to a 1480 because I had a ujoint let go and it took out my rear yoke.

Perfect... would you guys recommend swapping out the yoke to the 1480? Or would you just get the driveshaft built for the stock yoke?

If you tow a lot I don't see why not, they are beefier and can handle a little more (prolly why the LMM+ trucks with higher GVWR's come with them). That being said I haul a lot and my 1410 survived 200,156 miles before it exploded and took out the yoke. Had I swapped it out might have been ok and kept going, but since it did kill the yoke and my center carrier bearings were shot figured it would be a good time to throw on the Dmax 1 piece with the 1480 yoke and joints...

Mark the nut and the shaft so you know where to tighten it back to (dont want to overtighten because its a crush sleeve). Remove nut, use a puller, take the old one off, replace the seal while your in there, put new one on, torque nut back to where it was, fill back up with diff fluid, drink a beer, job well done.

Before you move forward you should confirm your u-joint size. At least some of the ZF trucks came with 1480.

The cap diameter on the 1410 is approximately 1.2 inch and the 1410 is 1.4

I don't understand why they don't have a kit for the eclb trucks if they have one for the cclb

Check out driveshaftspecialistdotcom, they can build one for you if it is a 4x4. The shaft is too long for the 2x4 in the Extended and Crew Cab models, max length IIRC on a 5" tube is 86" even with the 1480/1485 series ujoints and yokes
