ACL Race Oversized Rod Bearings for K-Series

The ACL Race Series 0.025mm Oversized Rod Bearing Set is designed for K20A2 and K24A engine builds that require a tighter tolerance due to crankshaft machining. When a crankshaft has been ground to a specific undersize, using standard bearings will result in excessive clearance, leading to oil pressure loss and potential engine failure. These oversized bearings restore the factory-spec oil clearance, ensuring your K-series engine runs smoothly under high performance.

Technical Advantages

• Precision Oversize: Engineered for 0.025mm undersized crankshaft journals.
• Durability: Features the renowned ACL tri-metal construction for maximum fatigue resistance.
• Performance Ready: Ideal for high-compression, turbocharged, or supercharged K-series setups.
• Reliable Fitment: Designed to meet the stringent demands of Honda K-series engine architecture.

These bearings are the preferred choice for professional engine builders who demand precision. By utilizing the correct oversized bearing, you ensure that your oil film thickness remains within the optimal range, protecting your journals and providing the longevity needed for street or track use. Whether you are building an RSX Type-S or a K-swapped Honda, these components deliver the performance you expect.
