ACL Bearings 4M2737H-STD Race Series Main Bearing Set for Nissan - VG30DE/VG30DETT

The ACL Bearings 4M2737H-STD Race Series main bearing set is engineered for high-performance Nissan VG30DE and VG30DETT engines. Manufactured to exacting tolerances with precision wall thickness accuracy, these tri-metal bearings deliver the durability and performance demanded by motorsports applications from drift racing to endurance competition.

Key Features:

• Tri-metal construction designed to withstand high RPM conditions, high stress loads, and elevated temperatures
• Large chamfers to accommodate larger crankshaft fillets for improved stress distribution
• 3/4 groove design optimizes bearing load carrying capacity and oil flow to rod bearings
• High strength overlay plate with reduced thickness for superior fatigue resistance
• Hardened steel backing maintains crush under high loads and temperatures
• Increased eccentricity compensates for bore distortion at high RPM and assists hydrodynamic oil film formation
• No flash plating on bearing backs to maximize heat transfer and improve bearing retention
• Increased crush and tighter wall tolerances ensure proper seating and consistent clearances

ACL Race Series bearings are recognized throughout the motorsports world and are standard components in championship-winning race engines. Standard size bearings are designed for use with standard diameter crankshaft journals. Manufactured with micron-level precision for consistent quality and reliability in extreme performance applications.
