Product Function
Connecting rod transmits the reciprocating motion of the piston to the rotational motion of the crankshaft. Forged steel construction ensures high strength and fatigue resistance for Isuzu 4HG1/4HF1 diesel engines.
Features & Advantages
- OE Quality: Manufactured to Isuzu dimensional and material specifications for perfect fit and reliable power transmission
- High-Strength Forging: Forged steel construction provides superior tensile and fatigue strength
- Precision Machining: Center-to-center length, bore roundness, and weight matched within tight tolerances
- Shot-Peened Surface: Enhances fatigue resistance and stress distribution
- Restores Engine Performance: Eliminates knocking, vibration, and power loss caused by worn or bent rods
- Direct Replacement: Matches OE weight, length, and pin/bearing diameters
- Cost-Effective: Affordable alternative to genuine Isuzu connecting rods
Vehicle & Engine Compatibility
This connecting rod is specifically designed for Isuzu NKR and NPR trucks with 4HG1 or 4HF1 engines.
Isuzu Truck Models:
- ISUZU NKR (NKR55, NKR57, NKR59, NKR71, etc.)

Installation Notes
Installation steps (overview):
- Clean the connecting rod and inspect for cracks or damage
- Install new connecting rod bearings (upper and lower halves)
- Lubricate bearings and crank journal with engine assembly lube
- Attach the piston to the connecting rod using the piston pin and retainers
- Install piston rings and compress them with a ring compressor
- Insert piston/rod assembly into the cylinder bore, guiding the rod onto the crankshaft journal
- Install the connecting rod cap with new bolts. Torque bolts to specification in stages
- Verify bearing clearance using plastigauge before final torque
- Rotate crankshaft to ensure smooth movement after all rods are installed
- Proceed with engine assembly
Quality Control
- Material Verification: Chemical composition and tensile strength tested
- Dimensional Inspection: Center-to-center length, bore diameters, parallelism, and twist verified
- Hardness Testing: Core hardness within specified range
- Magnaflux Inspection: 100% crack detection on forged blanks
- Weight Matching: Balanced for consistent reciprocating mass (when ordered as a set)
- Visual Inspection: 100% checked for machining defects, burrs, or surface flaws
