WHADDUP gents? I know it's in this forum, but not many search options from mobile phone. I wanted to know what max speed is on an '05 CCSB Sierra before a stock driveshaft makes brown? Thx.

 

above 100 mph, the limiter is set at 98 for a reason. is it aluminum? it can wipe out a lot of **** when it lets loose

 

Anything over 100mph is tossing the dice.

 

That was my suspicion... I'd read it somewhere (probably here) before, and have decided I'm gonna mod this thing afterall. Originally got truck as a parts/people hauler, but real project has added some time to its completion date. I can't happily drive a stock anything, so I'm diving in now... Thx.

 

yep go ahead a get a good driveshaft and take care of that before it turns into a problem!

 

Going to assume that the 2 piece shafts in the ex cab trucks are about the same?

 

Dunno bout the new ones.. but ive had mine up to 160mph
~6300 RPM of the driveshaft

 

Mother of god! I do feel a little safer now though lol. It's in an 03, so I doubt it changed much from your design.

 

haha!
i dont suggest it tho!

my buddy was racing a new at the time 08 or 09 mustang on the interstate and i was catching up with them and fixing to pass when a coupling blew off my turbo. It was awesome/dumbest thing ive ever done.
i havent got over 140 since..

 

I don't plan on taking it much over 120. OP sorry for the thread jacking.
