Balance shafts are used to make buyers of 4-cylinder engines comfortable because they don't see or feel vibrations.

> Balance shafts have been around since the early 1900's and they were invented to INCREASE THE LIFE OF ENGINES. Caterpillar uses them in several of their most popular engines. Several popular automotive engines use them.

Engines with balance shafts that are used in racing have their balance shafts discarded to reduce weight.
