Developed using Finite Element Analysis (FEA) to withstand the demands of NASCAR racing. Finite Element Analysis is a method for predicting the response of a geometric structure due to the environment it is being designed to function in. The process starts by creating a geometric model. The model is then subdivided, or meshed into many small geometric pieces, or elements of basic geometric shape. These basic shapes can easily give results for stress and strain where the larger geometric structure can not. Steel casting has nearly double the tensile and yeild strength and enlongation VS. cast iron Investment cast from 8620 steel 4130 steel bearing caps ARP bolts 3.250 differential bearing diameter Approximate weight: 21 lbs
