2002-2021 Subaru WRX & STi EJ20/EJ25
Manley H-Beam Rods have been forged from 4340, and have been heat treated, stress relieved, shot peened, and 100% individually mangafluxed to provide you the strength needed on your next high performance build.
These rods can handle up to 600 horsepower when combined with the right kind of hardware. If you’re rebuilding an engine, make sure that the Manley Connecting Rods is a part of the blue print.
