ACL BMW N54B30/N55B30/S55B30 3.0L Standard Size High Performance Rod Bearing Set

For BMWs with the N54B30, N55B30, or S55B30 3.0L engine, these high-performance rod bearings from ACL are a solid option when it's time to rebuild or refresh your engine. Rod bearings are critical for keeping your crankshaft spinning smoothly within the engine block, and these are built to handle more stress than stock.

ACL has been making engine bearings for a long time, and they've put that experience into this set. They use a tri-metal material construction that offers a good balance of strength and wear resistance, which is important for keeping your engine healthy under demanding conditions. This set is standard size, meaning it's meant to be used with a crankshaft that's still within factory specifications. If your crankshaft has been machined undersize due to wear or damage, you'll need a different size bearing set.

This set is designed to fit a range of BMW models including the 1 Series M, 135i, 335i, 335is, 535i, 740i, X6, and Z4. When you're doing an engine rebuild, using well-built internal components like these bearings is key to ensuring long-term reliability.
