Brian Crower 300M Alloy MOAR Connecting Rods for Toyota 2JZ-GE / 2JZ-GTE (BC6304M)

When building a 2JZ capable of producing over 2,000 wheel horsepower, every component in the rotating assembly must deliver uncompromising strength and fatigue resistance. The Brian Crower 300M Alloy MOAR Connecting Rods are engineered for the most extreme applications, offering exceptional tensile strength and durability without the compromises associated with aluminum connecting rods.

Manufactured from premium 300M alloy steel, these rods deliver an impressive tensile strength of 305,000 PSI—significantly higher than traditional 4340 chromoly steel at approximately 270,000 PSI. Enhanced with vanadium, copper, increased silicon, and molybdenum, 300M is the same alloy used in aircraft landing gear, where maximum fatigue resistance and structural integrity are essential.

Based on Brian Crower’s MOAR (“Mother Of All Rods”) design and equipped with ARP Custom Age 625+ 3/8" fasteners, these rods provide the ultimate combination of material strength, rigidity, and clamping force for engines operating at the highest levels of boost and cylinder pressure.

Trusted by professional engine builders and motorsport teams worldwide, Brian Crower 300M MOAR connecting rods are the definitive solution for reinforcing Toyota’s legendary 2JZ platform in four-digit and beyond horsepower builds.

Carefully selected for builders who demand proven performance without compromise.
