This is a set of connecting rod bearings that sit between the connecting rod and the crankshaft, reducing friction and wear in the engine's rotating assembly. Made from a high-performance tri-metal alloy, these bearings provide a durable, low-friction surface essential for smooth crankshaft rotation, unlike worn bearings that can cause excessive play and noise. Operators may hear a distinct knocking or tapping sound from the engine, especially under load, or notice a drop in oil pressure if these bearings fail.
Always verify with serial number before ordering.

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The most common symptom of worn connecting rod bearings is a distinct knocking or 'rod knock' sound from the engine, which often becomes louder under load. Continued operation can lead to increased engine vibration and a significant drop in oil pressure. The ultimate consequence of severely worn bearings is catastrophic engine damage due to the connecting rod impacting the crankshaft.
Always ensure the crankshaft journals are clean and within specified tolerances before installing bearings. Never reuse old bearing bolts; always use new ones torqued to the correct specification.
Inspect the crankshaft journals for scoring or wear, and check the connecting rods for straightness when replacing bearings.
