Rotating Assembly Balancing crank gear When having a rotating assembly balanced do I need the crank gear installed? I do not currently have one I need to know if I should buy one and install it before I take my stuff to the machine shop. I have read that the engine is internally balanced and I do not need the harmonic balance or the flywheel.

I have never heard of anyone balancing with the crank gear on, although I suppose it couldn't hurt.
However, I have ALWAYS been instructed by the machine shop to bring the harmonic balancer and flywheel/ flexplate for the balance.

that what I was wondering. I’ll be making more power than id like to put at a stock flywheel and don’t have the funds yet. I was thinking that when people swap to a better flywheel or balancer they don’t rebalance the crank

did they say if they make a difference. My machine shop said they could if I wanted to but it doesn’t make much of a difference with an internally balanced engine. They’re a very reputable shop so I’ll trust their word. Was just curious what other are doing.

LS engines are internally balanced engines. The flywheel/flexplate and harmonic balancer are not needed to balance LS rotating assemblies.
