What does '0.025mm oversized' mean for these rod bearings?

This means the bearings are slightly larger than standard size. They are intended for use when the crankshaft journals have been machined down by 0.025mm to ensure a proper fit and oil clearance after wear or during a performance rebuild.

What is the advantage of a tri-metal overlay bearing?

A tri-metal overlay is a common construction for performance bearings. It offers a good balance of strength, conformability, and embeddability, which helps these bearings withstand higher loads and temperatures while maintaining good oil film support.

Do these bearings come with installation hardware?

This product is a set of rod bearings only. It does not include any installation hardware or crankshafts. Always refer to the manufacturer's installation instructions for proper fitment and lubrication procedures.

Product Details

When you're rebuilding or modifying a Nissan VG30DETT engine, especially for higher performance, the rod bearings are a critical component. These ACL high-performance rod bearings are made to handle more stress than stock, making them a solid choice for builds that push the limits. They come at 0.025mm oversized, which is important if your crankshaft journals have been machined undersize during a rebuild to clean them up or correct wear.

ACL uses a tri-metal overlay on these bearings, which is a well-known design for its ability to withstand higher loads and temperatures. This construction helps maintain oil film integrity under demanding conditions, reducing friction and wear. The 0.025mm oversize means they are designed to fit crankshaft journals that have been turned down by that amount, ensuring a proper and snug fit for optimal oil clearance. This is a common step in performance engine builds to ensure everything is within spec after machining.

This set includes rod bearings for your VG30DETT engine. Make sure to check your crankshaft journal dimensions after any machining to confirm if the 0.025mm oversize is the correct fit for your specific build. Proper installation, including correct oil clearances and lubrication, is key to their performance and longevity.
