Premium-quality connecting rod assembly designed as a direct replacement for Isuzu NPR57 medium-duty trucks equipped with the 4BC2 diesel engine. Forged steel construction ensures high strength and fatigue resistance.

• OE Quality: Manufactured to Isuzu dimensional and material specifications
• High-Strength Forging: Forged steel construction for superior tensile strength
• Precision Machining: Tight tolerances for center-to-center length and bore roundness
• Shot-Peened Surface: Enhanced fatigue resistance and stress distribution
• Restores Engine Performance: Eliminates knocking, vibration, and power loss
• Direct Replacement: Matches OE weight, length, and pin/bearing diameters
• Cost-Effective: Affordable alternative to genuine Isuzu connecting rods

Specifically designed for Isuzu NPR57 trucks with 4BC2 engine.

• ISUZU NPR57 (medium-duty truck, 4BC2 engine)
• May also fit other Isuzu trucks using the 4BC2 engine (e.g., NPR59, NKR55 - verify)

• 4-Cylinder, Inline Diesel
• Displacement: 3.3L or similar (4BC1/4BC2 family)
• Application: NPR57, NKR, light/medium trucks

Installation steps overview:

1. Clean the connecting rod and inspect for cracks or damage
2. Install new connecting rod bearings (upper and lower halves)
3. Lubricate bearings and crank journal with engine assembly lube
4. Attach the piston to the connecting rod using the piston pin and retainers
5. Install piston rings and compress them with a ring compressor
6. Insert piston/rod assembly into the cylinder bore, guiding the rod onto the crankshaft journal
7. Install the connecting rod cap with new bolts and torque to specification
8. Verify bearing clearance using plastigauge before final torque
9. Rotate crankshaft to ensure smooth movement
10. Proceed with engine assembly
