is my driveshaft gonna fallout?

I have a single cab prerunner that I just put a 6 inch lift on it. The slip yoke on the tramsmission is slid out alot more now and you can see the slip shaft( I guess thats what its called) because the dust cover for it has slid apart about an inch. The prerunners single cabs have a 1 piece driveshaft. the slip yoke for them is where the drivesaft goes into the transmissiom. Anybody with a big prerunner single cab or a long travel reg cab have any input or experience with this

 

Heres a pic of the truck

 

Got some 35s on it bump

 

how about a pic of the drive shaft itself?

 

truck looks badass! are you regeared?

 

Thanks but no I didnt regear. it aint that slow, at least to me. I dont have to ride the clutch to get going.I took the 3 inch blocks off of it today. The output shaft was leaking oil and I had a moderate driveline vibration. I plan on getting a set of tapered and offset centerpin blocks from streetacos.com I forget the guys username but he is on tw.

 

damn man. good luck with it all, it looks sick. Functionality is obviously more important though haha

 

That kit didn't come with a driveshaft extension? I would have thought that the blocks would have been tapered also. Hopefully you get this sorted out!

 

It wasnt a lift kit it. I have lift spindles on front with bilstein5100s and I tied to use univesal 3 inch lift blocks
