JUst get a new drive shaft.

I've been 120 a couple of times, but I can feel a slight vibration over 100. Not fun at all lol

 

This is what 425 RWHP/430 ft-lbs did to my stock drive shaft. I got a 2007 RCSB with a 6.2, 3.73 gears, and stock 20's. Had to get a custom shaft and I had the new shaft up to 450 RWHP with no problems or vibration.

 

Did you go back with aluminum or steel? If aluminum .120 wall or .08?

 

I went with steel because aluminum would be to big and I plan on adding a magnacharger in a couple of months.

 

Stock driveshafts...

 

damnit man that is nasty!! lol yea whenever ive road in a truck i can hear the vibration, and my buddy says he can feel it when hes driving.. damn i dont want to go through that.. looks like im getting one built for sure.. any of you guys have any recommendations on a shop or certain company to get one made?

 

yes, +1.

 

Just get one built a friend of mine in an 07rcsb destroyed 2 before going and getting a built one. He hit 120 both times and they blew up. I wouldn't trust any nnbs drive shaft over 100.

 

Florida Powertrain and Hydraulics, Inc. built mine. They came to the shop at 2 pm took measurements and by 10 am the next day it was installed on the truck.

 

anybody else? should i just start checking local performance shops or is there somebody mainstream that alot of guys on the forum are going through? no sponsors i take it...
