Ive been wanting to buy the rrm crank pulley but i heard from a coupe guys for me to make sure that it is balanced, what does that mean? They said if its not it would eventually mess my car up.

 

We had that discussion a while ago, and RRM said their pulley was done right.

An unbalanced pulley would generate different loads at different angles and down the road tear your stuff appart due to the extra load/vibration.

Do you know how they used to get pagers to vibrate?
They'd put half a cylinder on a shaft and make it spin. Everytime the half cylinder would reach a specific angle, it would create a vibration.

I'm sorry, I can't find the words to describe it properly

 

yea i got it , thank's!!!!
