Mitsubishi Patented the balance shaft idea. Now that the patent has expired, others are using balance shafts. GM Ecotec engine is one example. I would not take it out.


I dont know about that. Balance shafts have been around for a long time. My 94 4.3 has one.

I know of alot of older German motors that have them.
