• Available with premium ARP fasteners: ARP 2000 bolts on Sportsman rods and ARP Custom Age 625+ bolts on BC625+ rods
• Sportsman rods rated for over 200 horsepower per cylinder
• BC625+ rods rated for over 300 horsepower per cylinder, ideal for high-horsepower forced induction builds
• Rod length of 5.886 inches with a weight of approximately 536 grams per rod
• Big end width of 0.780 inches and bore diameter of 2.008 inches for precise fitment
• Sold in sets of four to equip one engine fully

Construction & Design:

Brian Crower connecting rods are forged from premium 4340 billet steel, a material known for its excellent tensile strength and fatigue resistance. The H-beam configuration provides an optimal balance between rigidity and weight savings, reducing rotating mass while maintaining structural integrity under extreme loads. Each rod undergoes precision CNC machining to ensure exact dimensions and consistent quality, critical for high-performance engine applications.

The rods are paired with ARP fasteners tailored to the intended power level. The Sportsman rods use ARP 2000 bolts, which offer a tensile strength of 220,000 psi, providing reliable clamping force for moderate builds. The BC625+ rods feature ARP’s Custom Age 625+ bolts rated at 280,000 psi, delivering superior clamp load for the most demanding high-horsepower and high-rpm engines.

Installation & Fitment:

These connecting rods are direct-fit replacements for the 2AZ-FE engine in the specified Scion tC and xB2 model years, requiring no modifications for installation. They are designed to work seamlessly with OEM pistons and crankshafts, making them an excellent upgrade for engine rebuilds or performance enhancements. Installation should be performed by a qualified technician to ensure proper torque specifications and clearances are met for optimal engine reliability.
