Eagle Parts and Accessories

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 their lineup a few years later as well as expanding their 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. Eagle never stops researching ways to make their products lighter, stronger, more efficient to manufacture, and more diverse. When you stop moving forward, you get passed by the competition.

All Eagle H-beam rods are forged from certified 4340 chromoly steel. While a lot of companies make rods from this material, if you pay close attention, you will notice not all 4340 is the same. For instance, to be classified as "4340 steel" certain alloying elements must be present in certain percentages. AISI/SAE specifications call for 1.65% to 2.00% nickel content. While this seems like a small difference, understand that this is almost an 18% variation. 4340 steel with 1.65% nickel will act a little differently than 4340 steel with 2.00% nickel content. This is just one of many alloying elements involved in creating 4340 steel. Through extensive material testing, Eagle works closely with the foundry they use to achieve a much tighter tolerance of all alloying elements to their specific requirements. Along with this, the heat treatment and tempering process used is vital to producing a strong steel. While exactly what they do is a closely guarded secret, all of this attention to detail results in a stronger and much more consistent material. Eagle's "4340" steel routinely tests 10-15% stronger than "typical" SAE/AISI spec 4340 steel.
