When building a high-performance Acura or Honda engine, the foundation of your rotating assembly is critical. These ACL Race Series Main Bearings, featuring a 0.025mm oversize, are designed to provide the precise clearances required for high-RPM reliability and extreme load conditions. Engineered with advanced metallurgy, these bearings offer superior fatigue resistance and heat dissipation compared to OEM components.

Key Technical Features

• Tri-Metal Construction: Hardened steel backing with a precision-plated overlay for maximum durability.
• 0.025mm Oversize: Ideal for engines that have undergone minor line-honing or require specific oil clearance adjustments.
• High-Load Capability: Specifically formulated for race and street-strip applications where oil film integrity is paramount.
• Compatibility: Designed for a wide range of B-Series (B17, B18) and K-Series (K20, K24) engines found in popular platforms like the Integra, RSX, Civic, and Accord.

Whether you are refreshing a daily driver or building a track-ready powerhouse, these bearings ensure consistent oil pressure and reduced friction. The unique design geometry helps maintain a stable oil wedge even under intense thermal stress, protecting your crankshaft from premature wear.
