Clevite MS-1659A Engine Crankshaft Main Bearing Set

The Clevite MS-1659A Engine Crankshaft Main Bearing Set delivers the durability and dependability that professional technicians and engine builders demand. These precision-engineered main bearings are designed to protect your engine's crankshaft and ensure reliable performance in demanding applications.

Key Features:

• Bi-metal aluminum construction with 100% lead-free aluminum silicon alloy
• Engineered with 60% more silicon content than comparable competitive bearings
• Enhanced journal surface conditioning for improved wear characteristics
• Superior seizure resistance protects against bearing failure
• Exceptional wear resistance extends bearing service life
• OE-quality manufacturing standards for precise fit and performance

Clevite's advanced bi-metal bearing technology provides the optimal balance of strength, conformability, and wear resistance. The high silicon content in the aluminum alloy creates a harder, more durable bearing surface that better conditions the crankshaft journal over time, reducing friction and preventing premature wear. This complete main bearing set includes all bearings needed for a professional crankshaft installation.
