If you're building a B18C for boost or high RPM, the rods are where builds live or die. These aren't shelf queens — they're magnaflux tested, shot-peened, and rated to 1000+ horsepower at 8,200 rpm.

The I-beam race profile gives you the strength of an H-beam design in a lighter package — polished beams to eliminate stress risers, one-rib cap design for added bearing support, and ARP 8740 chromoly bolts at 200,000 psi yield strength.

Stroker clearanced from the factory. Floating pin. Weight matched set of 4.

If you know what a B18C is capable of, you already know why these matter.
