Brian Crower Connecting Rods - Nissan KA24DE - 6.495 - BC625+ w/ARP Custom Age 625+ Fasteners

Forged from high-strength BC625+ alloy, these Brian Crower connecting rods are built to handle the demands of a performance-tuned Nissan KA24DE engine. The BC625+ material offers a notable increase in tensile strength and fatigue life compared to standard 4340 steel, making it a solid choice for builds pushing beyond stock power levels. Each rod measures 6.495 inches in length, a common upgrade size that can influence piston speed and engine harmonics.

These rods come equipped with ARP Custom Age 625+ fasteners, which are a step above even ARP's popular L19 bolts. Custom Age 625+ bolts are known for their exceptional strength and resistance to stretching under extreme cylinder pressures and temperatures. This combination of a robust rod material and top-tier fasteners ensures reliability when you're demanding more from your engine, whether for track days or spirited street driving. The beam design is a robust I-beam, optimized for strength without adding unnecessary weight.

When rebuilding or modifying your KA24DE, upgrading the connecting rods is a critical step for durability. These Brian Crower rods are designed as a direct replacement for the factory units, simplifying installation into your existing crankshaft and piston setup. Ensure you have the correct torque wrench and follow the manufacturer's recommended assembly procedures for these high-performance components.
