A reinforced workover rig mast (40) is disclosed. A top section (60) of the mast (40) telescopes relative to a mid section (44), and includes a scoping cylinder area (72) for receiving a scoping cylinder (90) that may be used to extend and retract the top section (60). A number of external gussets (78) are located within this scoping cylinder area (72) to structurally reinforce the upper section (60). Other reinforcement features are incorporated by the mast (40) as well, including an increased width and depth, along with a reduced vertical spacing between adjacent cross supports (50b, 66b, 74).
