A winch drum tension isolation system includes a winch drum including an outwardly extending flange, the flange including a plurality of holes spaced along the flange. The winch drum tension isolation system also includes a locking mechanism positioned proximate the winch drum and including a locking member engageable with the flange. The locking member is movable between a first position, in which the locking member is received in one of the plurality of holes to prevent rotation of the winch drum, and a second position, in which the locking member is spaced apart from the flange to permit rotation of the winch drum.
