The Carrillo H-Beam Rod is a king of the connecting rod world in terms of strength, reliability, and quality control. Carrillo rates this rod as a 275hp rod, so a 4cyl could safely make 1100hp with this rod without overpowering it. They come with 3/8" CARR Bolts, which is a definite upgrade over the common ARP2000 bolts found in most rods on the market.
