Painless Autoworks caged pulley does not have the spline so 6lb pulley or lower is what is recommended for it to be ran.

This has never been used I picked it up awhile back but going a different direction with my build. It comes with an adapter to run a BHJ balancer or can use stock balancer.

600 OBO shipped this is the last version before the spline spindle was done.

Some have welded these and ran larger pulleys as well from what I was told.

Open to offers on this item as my plans have changed and not going to use this.

Thank you
