    Smile Lower LFP Pulley Vibration !!!

    Hi

    I finally finished my eaton swap and I crank the car and it went all OK with no issue! but I notice the Lower eaton Pulley has a vibration! So is this normal? it's not Vibrated a lot but it's noticeable! Dose the bolts has some kinda torque specs? or do I need a Harmonic balancer? it's on low RPM I can't go higher since the car is not tuned yet, So please guys I want to know if that's a normal or not.

    oh BTW it's 2lb LFP Pulley with stock upper and everything is tight and snug!

    Thanks everybody.

    If he needs a centering ring, he will have to contact LFP as that is where his lower came from. Does Trilogy need the centering ring?

    Don't call Rick about this, I did and he informed me that LFP is a copy cat company that steals their designs. That being said he couldn't guarantee me anything with a centering ring and I should contact them. This explains why their stuff looks just like Metco's. It looks like I could benefit from the ring as well.
