Description
By taking advantage of the latest development in valve spring wire chemistry and manufacturing techniques, KPMI has developed ovate wire Beehive style springs that will live and perform at a high level in Harley Davidson applications. By coupling these developments with strict KPMI design protocols and employing multiple design, simulation, and FEA analysis software, we were we able to overcome the torsional stresses unique to ovate wire springs that previously severely limited their operating parameters.
