Default LS1 Harmonic Balancer

Recently installed an underdrive pully on a 2000 Corvette Coupe, Automatic. Will this require harmonic balancing? Any help appreciated.

No. What brand Pulley? Hope it's ASP. Proper install is a must, though. Best wishes.

most pulleys are already balanced......they are usually not keyed...so they have to be fully balanced....only time you really have to worry is if you drop it and it knocks the thing out of whack.....or if you plan to spin up to 12000 rpm(indy cars)
