Before you buy a driveshaft If you have not purchased a drive-shaft before I STRONGLY encourage you to thoroughly research the products before you purchase. The #1 most recommended way to go is to put a 1 piece aluminum shaft in the vehicle. If you have a manual vehicle this could end up being a costly mistake. I personally do not care how many people recommend or talk about how great these shafts were for them. Because there are a percentage that wont enjoy there experience and I believe that now having it, others have shared there draw backs also. I am not saying that the product is poor, I purchased a drive shaft shop 1 piece thru Kollar racing and the shipping was fast, product came in tact, but if it generates harmonics you are stuck with that shaft. I was told over the phone (from drive shaft shop) that if it vibrates or causes any problems that it could be returned "no problems".. Well that is until there is a problem, pay the extra money and get a 2 piece shaft or carbon fiber. This is not to bash them because I feel they do make a great product, but anyone looking in the future may say them $$$ and headache of a runaround.

The harmonics occur because the factory did not pay attention to driveline angles. The two piece shaft removes the need for proper angles. If you have a vibration problem, get a digital angle finder with a magnet base. Take the driveshaft off. Measure the angle of the diff yoke, lets say it is 1.5 degrees up. Make the tailshaft of the trans 1.5 degrees down. Now the angles are parallel and the tailshaft to diff are about 1 1/2" offset so that gives you movement in the U joints. That should take care of the harmonics. Worked for me.
