Ten years prior to Eagle's official opening were spent developing the technology, relationships, and design that has become Eagle Specialty Products, Inc. Eagle formally began business in August of 1992 offering just a couple of part numbers. Eagle's commitment to quality and service has resulted in customer loyalty and satisfaction. This,in turn, has fueled rapid growth over the years. Eagle added crankshafts to our lineup a few years later as well as expanding our offerings in connecting rods. Continuous design improvements and improvements in materials and manufacturing techniques have resulted in Eagle being the largest and most respected aftermarket connecting rod and crank manufacturer in the industry. We never stop researching ways to make our products lighter, stronger, more efficient to manufacture, and more diverse.
