ACL Race Series 0.025mm Oversized Rod Bearings

For engine builders performing precision machine work on their Acura B18C1 or B18C5 engines, these ACL Race Series 0.025mm oversized rod bearings (4B1925H-.025) are essential. When your crankshaft has been turned or polished, standard bearings will not provide the necessary oil clearance. These oversized bearings allow you to maintain the perfect oil film thickness required for high-performance operation.

Key Features

• Precision Oversize: Specifically sized at 0.025mm over to accommodate machined crankshafts.
• Race-Proven Durability: Built with the renowned ACL Race tri-metal construction for superior load-carrying capacity.
• Optimized Oil Clearance: Ensures proper lubrication even under extreme stress and high RPMs.
• High-Performance Reliability: Ideal for VTEC engines pushed to the limit on the street or track.

Vehicle Fitment

Compatible with the following B-series VTEC engines:

• 1994-2001 Acura Integra GS-R
• 1997-1998, 2000-2001 Acura Integra Type R

Proper clearance is the difference between a long-lasting engine and a catastrophic failure. Ensure your machine shop has the right components for your build. For the best selection of performance engine parts, choose GGCRACING.
