Eagle CRS5137S3D H Beam Connecting Rods 5.137 Subaru EJ20 EJ257

Upgrade your engine's horsepower with a set of Eagle ESP H-beam connecting rods. Their 2-piece, forged, vacuum-degassed, 4340-certified steel construction provides outstanding strength, while still weighing much less than stock rods. Each rod is multi-stage heat-treated, x-rayed, sonic-tested, magnafluxed, 100 percent machined, and shot-peened to stress-relieve the metal. These rods have ARP 2000 3/8 rod bolts and precision cap alignment sleeves to positively locate each rod cap, silicon bronze bushings for floating pins. These connecting rods are the perfect choice for engines producing up to 900 horsepower (4 cylinder) or 1500 horsepower (6 cylinder). Each set comes with Instructions and rod bolt lubrication.
