ACL Race Series 0.25mm Oversized Rod Bearings

When your B18C1 or B18C5 engine requires a crankshaft grind, standard bearings are no longer an option. The ACL Race Series 0.25mm oversized rod bearings (4B1925H-.25) are engineered to provide the exact clearance needed for a professionally machined rotating assembly. These bearings are a favorite among engine builders for their consistent quality and ability to withstand the rigors of high-performance driving.

Technical Specifications

• 0.25mm Oversize: Designed for crankshafts that have been machined down to compensate for wear or damage.
• Tri-Metal Design: Features a hardened steel backing, a copper-lead intermediate layer, and a high-performance overlay.
• Superior Fatigue Resistance: Engineered to handle the high combustion pressures found in modified VTEC engines.
• Consistent Clearances: Provides the precise oil wedge required to keep your rod journals cool and lubricated.

Vehicle Fitment

This set is designed for the following Acura Integra models:

• 1994-2001 Acura Integra GS-R
