A hydroformed member having internal reinforcements and method of manufacturing the same. The method includes the steps of providing a die having a tooling cavity and a pair of opposing rams disposed in the tooling cavity. A tubular member is enclosed within the tooling cavity. The pair of opposing rams are then driven against opposing sides of the tubular member to form a pair of opposing indentations therein. While the rams remain in place, hydraulic fluid pressure is then applied within the tubular member causing the walls of the tubular member to closely conform to the shape of the tooling cavity and the pair of opposing rams.

[What is claimed is:] [1.]providing a die having a tooling cavity;providing a pair of opposing rams disposed in said tooling cavity;providing a tubular member;enclosing said tubular member within said tooling cavity;driving said pair of opposing rams against opposing sides of said tubular member to form a pair of opposing indentations therein;applying fluid pressure within said tubular member, said fluid pressure causing the walls of said tubular member to closely conform to the shape of said tooling cavity and said pair of opposing rams;maintaining said fluid pressure within said tubular member; andfurther driving said pair of opposing rams against said opposing sidewalls of said tubular member to further form said pair of opposing indentations dimension in said tubular member, said pair of opposing indentations being substantially adjacent thereby generally defining a point of contact between said opposing sidewalls.
