Magnum Harmonic Balancers

Just for clarification for anyone reading, 360/5.9 magnum balancers are not interchangeable with 360 LA balancers. They physically fit but the position and size of the counterweight differs.

A 5.9 magnum needs a 5.9 magnum balancer.
A 360 LA needs a 360 LA balancer.

Both are externally balanced, but are still different.

My understanding is that a 273, 318, 340 and 5.2 magnum all can use a common balancer since they are internally balanced. Can anyone comfirm this?


Also, there is an aftermarket balancer for the 5.9 magnum made by ATI which requires a custom pulley or custom spacer due to the body of the balancer being thicker than a stock unit. They are exceptional quality though.
