Eagle Acura B18A/B Engine (Length=5.394) Connecting Rods (Set of 4)
Item Description
standard rod for B18A, B18B, B20B, B20Z.


The factory connecting rods were not designed to make more power or rev higher than it came from the factory. If you are planning on racing your engine, it is a good idea to upgrade your connecting rod, and rod bolts at the same time. Eagle rods are one of the most cost effective connecting rods on the market. They come with ARP Bolts, and hold enough power and rpm to meet most peoples' goals. If you are unsure if this is the right rod for you, please contact one of our experienced sales reps today to help guide you through your build.

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 we use to achieve a much tighter tolerance of all alloying elements to our specific requirements. Along with this, the heat treatment and tempering process used is vital to producing a strong steel. While exactly what we do is a closely guarded secret, all of this attention to detail results in a stronger and much more consistent material. Our "4340" steel routinely tests 10-15% stronger than "typical" SAE/AISI spec 4340 steel.
