ACL BMW N63/S63 V8 0.025 Oversized High Performance Rod Bearing Set

Rebuilding the top end of your BMW N63 or S63 V8 engine? If you're dealing with worn connecting rod bearings, this set from ACL is a solid option. These are high-performance bearings designed to handle the demands of these powerful V8s. They are specifically sized at 0.025mm undersize, which is crucial if your crankshaft journals have been machined down to match this size during your rebuild.

ACL has been making engine bearings for a long time, and this set is well-built for performance applications. They use a tri-metal material construction that offers good strength and durability, especially important for high-revving or boosted engines like the N63 and S63. The 0.025mm undersize means they're meant to be paired with a crankshaft that's been ground down by that amount to ensure a proper fit and oil clearance. This is a common step when rebuilding an engine with bearing wear.

This set fits a range of BMW models including the 550i GT, 550i, 650i, 750Li, M6, X5, and X6. Make sure to confirm your specific model and year range. When installing, always follow the manufacturer's recommended torque specifications and lubrication procedures to ensure these bearings perform as expected.
