DNJ Engine Components Main Bearing Set Standard Size

The DNJ Engine Components Main Bearing Set in standard size is an engine crankshaft main bearing set for engine rebuilds and overhauls.

Key Features:

• Standard size bearings for engines whose crankshaft journals are at original factory dimensions
• Replacement main bearing design that restores proper oil clearance during a rebuild
• Helps reduce friction and wear between the crankshaft and engine block
• Supports a stable oil film for smoother engine operation and longer bearing life
• Supplied by DNJ Engine Components, a brand known for engine rebuild parts and gasket and bearing sets
