The ACL Bearings 4B8366-.50 is a high-performance connecting rod bearing set designed specifically for Toyota 3S-GE and 3S-GTE 1998cc inline-four engines. These rod bearings are 0.50mm oversize but maintain standard oil clearance specifications. ACL Race Series performance engine bearings are recognized as a premier brand throughout the motorsports world, with rod and main bearings that are standard components in race engines that have set records and won championships from sport compact drift racing to NASCAR, IHRA and NHRA competitions.

Key Features:

• Bearing material: F781 tri-metal construction
• Maximum overall length: 21.3mm (0.839 inches)
• Tunnel size: 51.004-51.024mm
• Shaft diameter: 47.985-48.000mm
• Maximum wall thickness: 1.488mm
• High strength overlay plate with reduced thickness for superior durability
• Hardened steel backs for robust support and longevity
