ACL Race Conrod Bearings Set – Subaru EJ20/EJ22/EJ25 (52mm Journal)

King Racing Conrod Bearings – 4B8296H Series (STD, 0.025, 0.25, 0.50)

King Racing 4B8296H Conrod Bearings are purpose-built for high-revving, high-load performance engines. Featuring advanced F781 tri-metal construction and race-developed tolerances, these rod bearings offer superior fatigue resistance, precise oil control, and long-lasting durability under extreme conditions.

The 4B8296H series is ideal for motorsport and high-performance street engines, with enhanced design features to maintain oil film integrity and minimise wear—even under the stress of aggressive tuning and high RPM operation.

Key Features

• High-performance tri-metal bearing with F781 material
• Hardened steel backing for improved support and housing retention
• Reduced overlay thickness for better fatigue resistance
• Increased crush for consistent bearing retention
• No flash plating for superior heat transfer and grip
• Tight, consistent wall tolerances for precision oil clearance
• Enlarged ID chamfers to suit large-radius performance crankshafts
