Help with vibration!
 

Ive got a vibration around 105mph, it was there before the drop and is still there. Is this common? Most won't notice it because its after the stock limiter.

I would assume driveshaft

Yep its the drive shaft, You have two options.

1). You have your stock drive shaft balanced for a higher RPM and hope for the best (This is the cheap route and everybody knows you get what you pay for)

2). Go to a reputable drive shaft shop and have you a drive shaft built. You can get a Two piece drive shaft W/Carrier bearing or you can get a one piece. I believe most people go the Two piece option.

your drive shaft is about to give you a big expensive fuck you.

hes right had it happen in a nnbs escb stock truck tuned thats it about 110 driveshaft broke , whitch broke the tranny in pieces got lucky truck was still farely new and the dealer fixed it
get a new d/s made

Thanks guys I'll hit the a drive shaft shop soon and keep it under 100.

im on the stock speed limiter for a reason.

:)

and it completely sucks donkey balls

My blow up is on here under Driveshaft Exploded.:sigh:. Dont think theres any sponsors on here still for driveshafts .. I got mine through Driveshaft Specialties of Texas in San Antonio .. One pc aluminum .. I opted for the heavy duty straight 5" aluminum high speed balanced Unlike that 5" taper to 4" thin wall stock bullcrap .. Plus They have different ones smaller diameter also ..but i hit 120 no problems no looking back with this one.. Good people to work with .. The person who will build it will be the one on phone askin u for measurements and all the particulars .. Cant beat it if u needa go that route IMO .. Im not putting no big HP yet but is in the plans so for ease of mind do it before u break shit :judge::nod::nod:

Mine start vibrating around 110 mph.. Took it over 120 mph.. Still have the stock driveshaft .. Soon will get one build ... If that thing breaks its Gona cost $$$$$ so get one if your Gona keep speeding like that ..
