• Integrated with ARP Custom Age 625+ fasteners, which are heat-treated and specially developed for high-stress engine environments, providing increased clamping force and preventing fastener stretch under load.
• Precision-machined to strict tolerances for perfect fitment and smooth operation within your engine assembly.
• Engineered to support high horsepower builds, including forced induction and stroker setups, by offering increased strength over stock rods.
• Compatible with a wide range of Acura B18A and B20 engines, making it a versatile choice for various performance builds.
• Designed to improve engine response, reduce vibrations, and support higher RPM operation.
• Finished with a durable surface treatment to resist corrosion and wear over time.

Construction & Design

The Brian Crower BC625+ connecting rods are meticulously forged from premium steel alloy, ensuring maximum strength and fatigue resistance. The rods feature a robust I-beam design that balances weight savings with structural integrity, allowing for higher RPM limits and improved engine responsiveness. The precision machining process guarantees exact dimensions and smooth surface finishes, which are critical for optimal bearing clearance and long-term durability.

The inclusion of ARP Custom Age 625+ fasteners enhances the clamping force and overall reliability of the connecting rods under extreme conditions. These fasteners undergo a proprietary heat-treating process that increases their strength and fatigue life, making them suitable for high-performance and forced induction applications. The rods are designed with a compact, lightweight profile that reduces reciprocating mass, contributing to quicker throttle response and smoother engine operation.

Installation & Fitment

The Brian Crower BC625+ connecting rods are designed as direct replacements for the factory rods in Acura B18A and B20 engines with a 5.394-inch length. Installation requires standard engine assembly procedures, including proper bearing clearances and torque specifications. Due to their precision engineering, no additional modifications or machining are typically necessary, but professional assembly is recommended to ensure optimal performance and longevity. These rods are suitable for high-performance builds, including stroker kits and forced induction setups, and are compatible with stock or aftermarket pistons.

• Bolt-on installation with standard tools and procedures.
