These high-performance H-beam connecting rods are precision-forged from aerospace-grade 4320 alloy steel, engineered specifically for the Alfa Romeo 1750 Nord engine.
Designed to withstand the stresses of high-RPM and forced-induction applications, these rods feature an optimal strength-to-weight ratio and are manufactured using multi-stage forging and heat treatment, ensuring exceptional fatigue life, dimensional stability, and resistance to micro-fracture under extreme conditions.
Material: 4320 forged steel (Ni-Cr-Mo alloy) for high core toughness and surface strength
Design: H-beam architecture for superior rigidity under compressive and tensile loads
Precision machining: Fully CNC-machined with tight center-to-center tolerances
Weight matched: Set tolerance within ±1 gram for dynamic balance
Fasteners: Equipped with ARP 2000 or optional L19 bolts
Big End Size: OEM spec (undersized bearing options available)
Application: Suitable for naturally aspirated and turbocharged Twin Spark builds exceeding factory output
Recommended for: performance engine builds, high-compression applications, and turbocharged 1750 Nord projects where connecting rod integrity is critical.
