Brian Crower MOAR I-Beam ProH625+ Connecting Rods for Toyota 2JZ-GE / 2JZ-GTE (BC6307)

When building an extreme-horsepower 2JZ, every bottom-end component must be capable of withstanding the highest levels of boost, RPM, and cylinder pressure. The Brian Crower MOAR (“Mother Of All Rods”) I-Beam Connecting Rods with ARP Custom Age 625+ fasteners are engineered to provide the ultimate combination of strength, rigidity, and clamping force for the most demanding street and motorsport applications.

Developed with input from leading 2JZ engine builders and tuners, the MOAR Series is approximately 50 grams heavier than Brian Crower’s proven ProH design, adding substantial material in critical areas to maximize fatigue resistance and structural integrity. The I-beam profile provides increased beam-to-cylinder-wall clearance for stroker applications, while reinforced pin-end construction helps maintain precise wrist pin bore roundness under extreme cylinder pressures.

Manufactured from aerospace-grade 4340 chromoly steel and equipped with ARP Custom Age 625+ fasteners, these rods are designed for engines operating at the highest levels of horsepower while retaining standard Toyota rod journal dimensions and bearing compatibility.

Trusted by professional engine builders and motorsport teams worldwide, Brian Crower MOAR connecting rods are a proven solution for reinforcing Toyota’s legendary 2JZ platform without compromise.

Carefully selected for builders who demand proven performance without compromise.
