ACL 1958-1980 Chrysler Prod V8 383/400/440 .20mm Oversized Trimetal Rod Bearing Set

ACL uses a Trimetal construction, which is a popular choice for performance and heavy-duty applications because it offers good embeddability and strength. This means the bearings can conform to minor imperfections in the crankshaft surface while still handling the significant loads placed on them by the connecting rods. Installing these bearings is a key step in an engine rebuild or repair, ensuring proper oil clearance and reducing friction for a healthier, longer-lasting engine.

When you're rebuilding or repairing your engine, getting the right bearing size is critical. These are a .20mm undersize bearing, meaning they are designed to fit a crankshaft that has been machined down by 0.20mm. Always confirm your crankshaft journal size before ordering to ensure a proper fit and oil clearance.
