ACL Ford/Mazda 4 2.3L DOHC Duratec Race Series Engine Connecting Rod Bearing Set

This is a set of ACL Race Series connecting rod bearings, specifically sized at 0.025 inches undersize. These bearings are built for performance applications, meaning they're made to handle the extra stress and heat that comes with a modified or race-focused engine. They're designed to provide a solid foundation for your engine's rotating assembly, ensuring proper oil clearance and support for the crankshaft.

When you're building or rebuilding an engine for performance, getting the bearing clearances just right is critical. These undersize bearings are intended for use when the crankshaft journals have been machined down to match this specific size, ensuring a tight and accurate fit. Make sure to check your crankshaft measurements before ordering.
