Extendable mast systems and methods for a material handling vehicle (20) include a base mast (32) having a first web (60) connecting a first web first flange (52) and a first web second flange (56); a base mast bearing (76); a base mast bumper (84); a vertically extendable mast (28) having a second web (72) connecting a second web first flange (64) and a second web second flange (68); and a vertically extendable mast bearing. The base mast bearing is spaced apart from the second web first flange defining a base mast bearing space (87) between the base mast bearing and the second web first flange. The vertically extendable mast bearing is spaced apart from the first web first flange defining a vertically extendable mast bearing space between the vertically extendable mast bearing and the first web first flange. And the base mast bumper maintains the base mast bearing space between the base mast bearing and the second web first flange.
