ACL Race Series Extra Oil Clearance Main Bearings for Nissan VG30DETT

For high-performance engine builders pushing their Nissan VG30DETT beyond stock limits, oil management is key. These ACL Race Series main bearings with extra oil clearance (HX-Series) are specifically designed to allow for a slightly thicker oil film. This is crucial for engines operating at high RPMs or under heavy boost, where increased heat and load can compromise standard clearances.

Performance Advantages

• Extra Clearance (HX): Provides increased oil flow to help manage heat and prevent bearing-to-journal contact under extreme stress.
• Tri-Metal Construction: Combines a steel backing, copper-lead intermediate layer, and a babbitt overlay for unmatched durability.
• High-RPM Stability: Engineered to remain stable and prevent oil starvation during high-speed operation.
• Precision Fitment: Designed to meet the unique demands of the VG30DETT block and crankshaft geometry.

By increasing the oil clearance, these bearings help reduce friction and improve cooling in high-output engines. They are the preferred choice for tuners building turbocharged 300ZX models or other VG30-powered platforms who demand reliability under pressure. Always verify your specific oil clearance requirements with a qualified machinist before installation to ensure the perfect setup for your power goals.
