ACL 4B1609H-.25 Performance Rod Bearing Set

The ACL 4B1609H-.25 Performance Rod Bearing Set is engineered for automotive applications that demand high durability and performance. These trimetal engine bearings are specifically designed to endure the rigors of higher RPM conditions, making them an ideal choice for performance builds.

Key Features

  • High-Strength Overlay Plate: Features a reduced thickness that enhances fatigue resistance, ensuring longevity under extreme conditions.
