High-strength forged alloy steel Connecting Rod with precision-weight-matched (

Connecting Rod 8-94392376-1 For Isuzu 700P FVR 4HK1 6HK1 Engine 8943996612

• Metallic knocking / heavy "clanking" from the crankcase that worsens under load
• Low oil pressure due to a failed big-end bearing (a direct consequence of rod misalignment)
• Engine vibration caused by an unbalanced rod weight or a cracked I-beam
• Misfire or compression loss (a bent rod can cause a piston skirt to impact the crankshaft counterweight)

• Manufactured from high-strength forged alloy steel, heat-treated for superior fatigue resistance
• Precision-weight-matched (±2 grams) to prevent imbalance and engine vibration
• Factory-installed, fully floating wrist pin bushing for a precise piston pin fit
• 100% inspected for cracks using magnetic particle inspection (MPI) — a non-destructive test standard for aerospace and heavy-duty engine components
• Each rod undergoes metallurgical microstructure analysis to verify uniform grain flow, ensuring no weak points in the I-beam structure that could lead to premature failure

• OE Quality – Manufactured to strict Isuzu OEM dimensional and material standards for a perfect, direct-fit replacement.
• Critical Safety Component – The connecting rod is the most highly-stressed component in the engine, transforming explosive combustion into rotational force. A cracked or bent rod leads to a thrown rod, penetrating the engine block and causing catastrophic failure.
• Forged I-Beam Construction – High-strength alloy steel forging provides exceptional resistance to bending, twisting, and fatigue under the high cylinder pressures of the 4HK1/6HK1 turbo diesel engines.
• Full-Floating Piston Pin Design – Precision-bushed small end reduces friction and wear between the pin and connecting rod, eliminating the need for press-fit pins and extending service life.
• Weight-Matched (±2 g) – Prevents engine imbalance and vibration, a critical requirement for high-RPM common-rail diesel engines.
• 100% Crack-Tested – Each rod undergoes magnetic particle inspection (MPI) to guarantee no surface or subsurface cracks; batch sample destructively tested to verify fatigue strength under cyclical loading.
• Restores Engine Performance – Replacing a bent or damaged rod with a precision-weight-matched assembly restores compression, eliminates engine knock and vibration, and returns full power and torque output.
• Direct Replacement – Simple bolt-in installation (professional engine builder required) — no modifications, re-balancing, or custom machining needed.
• Long Service Life – Designed for 500,000+ km of heavy-duty commercial operation, urban delivery, construction site work, and off-highway equipment use.

• Individual Packaging – Each connecting rod is oil-coated, individually sealed in a VCI anti-corrosion bag, and boxed with OE-style part labeling.
• Wholesale / Bulk Orders – Available for heavy-truck parts distributors, engine rebuilders, workshop chains, fleet operators, and international exporters — sold in case packs of 6, 12, 24 units (full 4- & 6-cylinder engine sets); pallet pricing available for volume orders.
• Customization – Neutral or private-label retail packaging (including custom barcode labels) is available for volume wholesale orders (minimum order quantity applies). Discuss your branding requirements with our sales team.
• Fast Shipping – Ready stock for immediate dispatch worldwide via express courier (DHL, FedEx, UPS) for urgent engine overhauls, or economical sea freight from central logistics hubs.
• Wholesale Support – Long-term supply agreements, tiered commercial pricing, and drop-shipping options available for approved distributors. Contact our engine parts department to set up a wholesale account today.
