King Engine Bearings Main Bearing Set Holden Alloytec

King Engine Bearings crankshaft main bearing sets for the Holden Alloytec 175/190 V6 are engineered to replace worn main bearings during an engine rebuild or refresh. They are also sold as engine crankshaft main bearing inserts and main bearing shells. The bearings support the crankshaft and keep a thin oil film between the journal and the bearing surface, which helps the engine run smoothly and last longer.

Key Features:

• Bimetal construction: aluminum-silicon base material
• SI-series design: King's SI series uses a silicon-aluminum alloy from its Alecular bearing technology. The silicon content is meant to improve wear resistance and durability under medium loads.
• Lead-free material: King's aluminum-silicon bimetal bearings are 100% lead-free.
• Multiple undersize options: the product line is available in several sizes to match the condition of the crankshaft journals.
• Precision manufacturing: King makes its bearings in-house, from raw materials through to packaging.
