ACL 6B2640HX-STD High Performance Rod Bearing Set
The ACL 6B2640HX-STD rod bearing set is engineered specifically for high-performance applications, featuring a robust tri-metal construction that enhances durability and performance under demanding conditions. Designed for the Nissan VQ35DE 3.5L V6 engine, these bearings are built to withstand higher RPMs, making them an ideal choice for both street and track applications.
Key Features
- High Strength Overlay Plate: The overlay plate is optimized with reduced thickness, improving fatigue resistance and overall performance.
- Hardened Steel Backs: Each rod bearing incorporates hardened steel backs, enhancing support for the bearing lining and ensuring secure retention within the housing.
- Increased Crush: This design feature enhances bearing retention, providing a stable interface even under extreme conditions.
- Improved Heat Transfer: The elimination of flash plating on the back of the bearings facilitates better heat dissipation, maximizing grip between the bearings and their housing.
- Enhanced Eccentricity: Designed to counteract bore distortion at high RPMs, this feature assists in the formation of hydrodynamic oil films for improved lubrication.
- Optimized Oil Flow: The 3/4 grooved main bearings increase the load-carrying surface area, enhancing oil flow to the conrod bearings.
- Tight Wall Tolerances: Consistent wall tolerances maintain precise clearances, contributing to reliable engine performance.
- Enlarged ID Chamfers: Chamfers on bearing edges accommodate larger fillet radii on performance crankshafts, ensuring compatibility with upgraded components.
