9.5SF Swap

[Dantheman1540]

Buddy got it all fixed up for me while I'm at work. The driveline shop in town only had another greasable but highly recommended getting the drive shaft redone to accept a 1350 so I don't need a bastard conversion joint. They also recommended getting a HD 1350 with billet straps. So I'll treat it nice for a few weeks until they have time to mill it open to 1350 and get the bigger joint and straps.

Nice. Had that been an 8.6, it might have let go first! The GMT900 2500 and the 1/2-ton K2 all went to a 1410 because of the increased torque of their motors. Well, the 2007 2500s had the smaller u-joint.

Yep that 240k mile G80 was ready to go at the next clutch dump. The drive shaft shop said it was the greasable joint that caused the failure. Said they are terrible for any performance application. So I need to get the driveshaft in the shop soon so I can run a solid 1350.

Found something even better than a 1350. These will allow me to have my shaft redone to accept a 1410 and not have to worry any more hopefully

I'm double checking with the manufacture to see if that flange yoke will fit the 9.5sf since it just says 14 bolt. Hopefully hear back today and start ordering stuff. Drive shaft shop said they are slow right now so It would only be 2 or 3 days to get it re yoked.

This looks like an even cheaper option. Gonna get a hold of them and see if it is what I think it is and if its really that cheap.

These only fit Full floater 14bolts with 10.5 or 11.5 ring gears.

However nitro makes exactly what I'm looking for its just more expensive then the dennys driveshaft option so I will see what they say. https://www.nitro-gear.com/GM-9-5-30-Spline-1410-Pinion-Yoke-p/yokgm9.5-1410-30u.htm

Dennys Driveshaft called and answered all my questions! They were awesome to talk to. The yoke they have listed for $48 is exactly what I need to convert the rear end to a 1410 joint and it is made in America by AAM axle corporation which means it's not made out of Wuhan Chineseium. So that's ordered and whenever it gets here the shaft will go get yoked to 1410 as well.

I 100% believe that if I simple had a solid joint instead of greasable, an auto tranny to slowly load up the driveline and skinnier tires this would have never happened. But that's why stick shift and fat sticky meats are fun!

"Fat sticky meats", I knew a girl like that once, just once!

1350 vs 1410 yoke.

Gonna pull the shaft Sunday evening and send it to get reyoked as well as pull the panhard for powder. Hopefully have it all together by the end of the week.

Guess I'll be driving the *** trap to work
