Customers look for safety and comfort, thus they are crucial to the success of car marketing. The McPherson suspension system, one of the most popular shock absorbers, has a history of excellent performance. Its unexpected demise and sudden fracturing, however, made it clear that the system needs thoughtful adjustments. The most important components of the shock absorber system that require improvement are the strut mount and spring. Because of the forces produced by vibrations caused by bumpy roads and the continuous severe load they are under; they often fail first. As a result, softwares like Shape and ANSYS is utilized in this research to simulate various alterations of the suspension system and compare it to a previously established base model. The results indicate that wave springs absorb more of the load and deform less under the same load as coil springs after testing numerous spring geometries and parameters. Although there was a minor increase in deformation due to vibrations when using the wave spring, it is certain that with further changes, the wave springs may completely absorb the disturbance and have a longer life than the shock absorber with the coil spring.
