Due to the great competition between truck manufacturers and the entry of new legislation to reduce emissions of polluting the structure of the vehicles suffered weight changes, with increased efforts on the chassis. In this context it is necessary to the continued development to improve the structural behavior in order to reduce costs, reduction of pollutant emissions and gains in vehicle performance. Shape optimization and reduction of the mass of the chassis structure, present themselves as alternatives for this purpose. The chassis is responsible for giving strength and stability to the vehicle front load requests and, therefore, is considered the most significant component of an automobile. The cross-cutting elements of chassis, are responsible for the improvement of resistance to twist the chassis. The rigidity of the element being influenced by its geometry, as mass reduction strategy optimization of the geometry of the part. This research seeks to analyze the shape optimization of sleepers for mass reduction using finite element calculations and computer simulation, without changing the mechanical properties of project. The results recorded in this study were very expressive, but the need for validation of the same with field testing
