ACL Nissan KA24DE Inline 4 .025mm Oversized High Performance Main Bearing Set

This set of ACL main bearings is built for Nissan KA24DE engines, specifically for builds that have been machined .025mm oversize. Main bearings are crucial for keeping your crankshaft properly supported and aligned within the engine block. When they wear out, you can experience increased engine noise, oil pressure issues, and eventually, catastrophic engine failure. These ACL bearings are well-built to handle the demands of performance applications, ensuring smooth rotation and consistent oil clearance.

This set includes all the main bearings you'll need for a KA24DE rebuild. They are designed to fit directly into the engine block after the main journals have been machined to the .025mm oversize specification. If you're rebuilding your KA24DE for more power or just to bring it back to life, using properly sized and well-made bearings like these is a key step for a lasting engine.
