• .50mm undersize specification for machined crankshafts
• Precision tri-metal construction for superior durability and wear resistance
• Strict dimensional tolerances ensure proper oil clearance and bearing crush
• Compatible with 1969-1996 Toyota models including pickup trucks, 4Runners, and Celicas
• OE-quality performance for professional rebuilds and restorations

ACL Bearings is a trusted name in engine bearing technology, manufacturing high-performance bearings that meet or exceed original equipment specifications. These rod bearings are essential components for any 20R or 22R engine rebuild, providing the reliable protection needed between the connecting rods and crankshaft journals. The undersize specification allows machinists to restore worn crankshafts to like-new condition while maintaining proper bearing clearances for optimal oil film thickness and engine longevity.
