Import 4340 Chrome Moly Connecting Rods For Mazda 2.0l — Buy in wholesale FOB from Supplier in China

These 4340 chrome moly connecting rods are precision-engineered for Mazda 2.0L engines, using 40CrNiMoA alloy steel as the base material. The rods undergo heat treatment to achieve a hardness of HRC 34-38, ensuring superior tensile strength and fatigue resistance under high-RPM conditions. Each rod incorporates a copper bushing made from QAL10-3-1.5 for reduced friction and improved lubrication, while dowels crafted from 40Cr with HRC 40-42 hardness provide structural stability at the joint interfaces.

The 40CrNiMoA grade is a standard nickel-chromium-molybdenum alloy widely used in performance connecting rods for its balance of toughness and machinability. Typical industry specifications for such rods include a yield strength of 900 MPa typical and elongation of 12 percent typical, with surface finishes often held to Ra 0.8 micrometers typical to minimize stress concentrations. These rods are designed to meet or exceed OEM dimensional tolerances for Mazda 2.0L applications, with bore diameters and center-to-center lengths matched to stock or aftermarket crankshafts.

Engine builders and tuners source these rods for high-performance street or track builds where stock components cannot handle elevated cylinder pressures. The rods are supplied as a matched set, ready for direct installation in Mazda 2.0L blocks without additional machining. Buyers should confirm compatibility with their specific engine revision and intended power levels, as clearances and balancing may require adjustment for extreme builds. Lead times, MOQ, and incoterms are provided on request from Hurricane Speed & Performance in Chengdu, Sichuan.

Hurricane Speed & Performance is based in Chenghua, Chengdu, Sichuan, China, operating from a facility in the 610081 postal district. The company specializes in high-strength engine components for performance and racing applications, with a focus on connecting rods, crankshafts, and related drivetrain parts. Its profile indicates a harbor-tier trust level, though response metrics are currently unavailable, suggesting buyers should request direct confirmation for inquiries.

The supplier’s product range centers on alloy steel components for automotive tuning, with the Mazda 2.0L connecting rods representing a core offering. No additional certifications, client lists, or production scale details are provided in the listing, so verification of quality systems, capacity, and lead times should be conducted prior to ordering. The address and regional presence in Sichuan align with China’s established manufacturing base for performance parts.
