when i hit 85mph+ the clutch pedal and the shifter start to vibrate rather hard. It even continues to vibrate when i put it in neutral at 85mph+. whats the deal? Thanks for the help fellars Cory

 

It's probably the driveshaft.......

 

uhhh what about the driveshaft? solutions?

 

On your avarage LT1 the stock steel driveshaft can become unbalanced over time. A couple options to remedy the problem are getting an LS1 driveshaft or a 1LE driveshaft. Both are made of aluminum and seem to work well with stock applications. Our steel driveshaft is probably stronger though.....

Another option is a carbon fiber peice but they're around $800.

A search will provide alot of info.

The best option is either try to get it balanced or get a brand new 1le(since it is stronger then the ls1) or get a used ls1 DS. I'm in the exact same situation you are right now. I'm trying to find a used ls1 ds right now. Whatever you do don't get the carbon fiber ds. Carbon fiber Ds's are good but not the ones you get for around 700-800 bucks. THe good ones are around 1500. So you would be better off getting the aluminum 1le.

 

Buy a used 1le, thats what I'm gonna do, I have the same issues as you do. the 1le is stronger then the ls1 shaft. and cheaper
