What is the CT-1 coating on these bearings?

The CT-1 coating is a dry lubricant applied to the bearing surface. It helps to reduce friction and wear, especially during the initial engine break-in period, contributing to a longer bearing life.

Why are these bearings 0.25mm oversized?

These bearings are 0.25mm oversized to fit crankshaft journals that have been machined undersize during a previous rebuild or to achieve a tighter oil clearance. It's crucial to measure your crankshaft journals to ensure they match the bearing size for proper fitment and oil clearance.

What else do I need to consider when installing these bearings?

Proper installation is critical. You'll need to ensure your crankshaft journals are clean and within the specified tolerance for 0.25mm oversized bearings. Always use a reliable torque wrench to tighten the connecting rod caps to the manufacturer's specifications and check the oil clearance.

Product Details

Rebuilding the engine on your VG30DETT-powered Nissan or Infiniti? These ACL high-performance rod bearings are a solid choice, especially if you're looking to get the most out of your build. They're designed to handle the increased stresses that come with performance modifications or just to ensure a reliable rebuild with updated components.

ACL has been making engine bearings for a long time, and they know what it takes to make them last. These bearings feature a special CT-1 coating, which is a dry lubricant that helps reduce friction and wear, particularly during the critical break-in period. This coating is a notable upgrade over standard bearings. They are also 0.25mm oversized, which is important if your crankshaft journals have been ground down during a previous rebuild or to achieve a tighter oil clearance for improved oil pressure. Always confirm your crankshaft journal size before ordering.

When you're putting an engine back together, especially a performance-oriented one, using well-built internal components like these ACL bearings is key to a long-lasting and powerful result. Make sure to follow the manufacturer's installation instructions carefully, including proper torque specifications and oil clearance checks.
