Brand new state of the art finite element analysis software has allowed the KPMI® engineering department to reduce the mass of our heat treated steel retainers. Lightening holes have been added to the steel retainers without sacrificing any strength or durability. All shoulders and cross sections were also analyzed for other opportunities to further reduce mass. These efforts led to mass reductions of up to 25% over the O.E.M. retainers.
