Description

The King CR6664SI is a set of SI-Series connecting rod bearings, designed as a superior OE replacement for Buick V6 engines. These bearings are constructed from a durable bimetal material with a silicon base, offering enhanced reliability and longevity for your engine. These SI-Series bearings are engineered with improved oil clearance, which works to reduce wear and extend engine life. This reduction in wear also contributes to less operating noise and vibration, providing a smoother and quieter driving experience. Specific fitment details indicate these bearings are compatible with select Buick models, including the 1988-2005 Buick LeSabre and the 2006-2008 Buick Lucerne. They are also noted as fitting Commodore models from 11/90 onwards.
