Well, the balance shafts are a pair of cam-like weight shafts that rotate in-sync with the engine. They are driven by a chain off the crankshaft. That box incases them and oils the shafts. The end comes off (we never bothered, we just cut the chain) and you can remove the gears off them and remove them that way. They require timing and must be set at TDC before timing. They are for "second order" vibrations. Most 2.5s have them but a great number don't. No 2.2Ls had them and early 2.5s and 2.5L Dakota engines lacked them also.
Basically... they do almost nothing.
The gains from removing them-
12-14hp
Less about 10lbs
Oil pan holds 5.5 qts of oil
Quicker revs
