GS Engineering has developed a series of lightweight, durable, and high-performance components for HMMWV/GMV1.0. This equipment has been proven tough through rigorous government RAM-D testing and is fielded by warfighters in the most severe environments. Designed with customizability and modularity in mind these components increase carrying capacity while maximizing mobility. Allowing the HMMWV to be quickly tailored to each mission.

This lightweight technology and design methodology has been successfully adapted by GS Engineering to other vehicle platforms, from ATVs to MRAPs and pickup trucks. Through effective topology development and optimization approaches, weight reduction can be achieved while improving overall stiffness and dynamic response. GS Engineering can integrate this lightweight technology into your vehicle platform or customize it to meet your specific requirements. 


Having achieved this lightweight design, GS Engineering received a Tibbett’s Award from the Small Business Administration at the White House for the work on this SBIR. This award recognized the critical role GS Engineering has in lightweight research and development for the government, success in driving innovation, and creating new jobs. GS Engineering was one of only 18 companies recognized in 2013 and the only company in the Midwest to receive such recognition.
