Precision-Engineered NK29-6200-AA OEM Connecting Rod for High-Performance Automotive Applications

Crafted from forged alloy steel for exceptional tensile strength and fatigue resistance, ensuring durability under extreme engine stress. Features CNC-machined bearing surfaces with micron-level tolerance (±0.002") for seamless crankshaft integration. Shot-peened finish enhances structural integrity while weight-matched sets (within 5g) guarantee balanced rotation.

Direct replacement for OEM 4000116669 with 100% interchangeability - no modifications required. Ideal for turbocharged/supercharged engines, performance builds, and heavy-duty fleet vehicles. Includes anti-friction coating on wrist pin bore to reduce wear in high-RPM applications.

Batch-tested for metallurgical consistency (SAE 4340 steel) and magnetic particle inspected for micro-fractures. Bulk packaged in corrosion-inhibiting vapor barrier for long-term storage. Wholesale quantities available with factory-direct pricing for workshops and distributors.
