Connecting Rod Bearing Set Standard Infiniti QX30 Q50 Q60 2.0L Turbo M274 12117HG00G

Connecting rod bearings are high-precision wear components that support the reciprocating motion of the engine's pistons. In the turbocharged M274 engine, these bearings are subjected to intense pressures and heat; over time, oil film breakdown or contamination can lead to surface scoring and "rod knock." Replacing these bearings at the first sign of wear or during a routine engine refresh is critical to prevent catastrophic crankshaft damage. This premium standard-size set is manufactured to exact Mercedes-design tolerances, utilizing advanced multi-layer materials to provide superior fatigue resistance and maintain essential oil pressure for long-term engine reliability.
