Camshaft bearings support the camshaft's journals and give them a smooth surface to turn on. This premium-grade engine camshaft bearing set is built for the demands of today's engines and offers these features:
- A-Series bi-metal aluminum: gives greater seizure resistance than tri-metal material.
- Wear reduction: designed to dramatically reduce, or eliminate, bearing wear.
- Added silicon: provides greater surface hardness. The silicon particles help polish the journal to further reduce wear during operation.
- Certified manufacturing: produced using ISO and QS certified manufacturing.
Signs that camshaft bearings may need replacing include low oil pressure, or worn or scored bearings and cam journals found during teardown. Other faults can cause the same signs, so diagnose the cause before replacing parts. The listed applications use one set per application, and this listing includes one camshaft bearing set. Country of origin: Mexico.
