Construction & Design:

Manley’s H-Beam connecting rods are forged from high-strength steel and engineered with a robust H-Beam cross-section that offers superior resistance to bending and twisting forces. The rods are precision machined to exact tolerances, ensuring consistent performance and fitment. The use of ARP 8740 steel bolts provides enhanced clamping force and fatigue resistance, critical for high-performance applications.

The .9848-inch pin bore is designed for tight, accurate wrist pin fitment, reducing play and wear during operation. This combination of materials and design choices results in a connecting rod set that balances strength, durability, and weight, making it ideal for both street and race engines.
