This is the Hot Racing Quick Change Oneway assembly. Installing or removing an included pin, racers can change from conventional full-time 4WD to a racing style one-way action. This center one-way transfers power to the front differential under acceleration but allows it and the front diff. to "freewheel" while decelerating or braking. Unlike a front one-way differential, a center one-way allows front differential action. Designed with telescoping chamber and rubber o-ring to shield the one-way bearing sections from dirt. Since the "freewheel" is not constant, there is little concern of drag from the seal.

Tips:
Use the locked 4WD mode for tearing up your local bashing spot, and the one-way mode for racing tight tracks where maximum off-power steering is needed.
