• Optimized for medium-load engine applications
• Particularly well-suited for engines equipped with nodular cast iron crankshafts
• Precision-manufactured to tight tolerances for improved oil clearance and reduced journal wear
• Helps reduce operating noise, vibration, and excessive oil consumption
