Description:

Building a B18B for boost? The rods are where it either holds together or doesn't.

These I-beam race rods are magnaflux tested, shot-peened, and rated to 1000+ horsepower at 8,200 rpm. The I-beam profile keeps weight down without sacrificing strength — polished beams eliminate stress risers, one-rib cap design maximizes bearing support, and ARP 8740 chromoly bolts come in at 200,000 psi yield strength.
