What is the purpose of the pMaxKote coating on these bearings?

The pMaxKote coating is an advanced surface treatment designed to reduce friction and improve wear resistance. This is particularly beneficial during the engine's break-in period and under demanding operating conditions.

Why are these bearings 0.25mm undersize?

The 0.25mm undersize specification is used when the crankshaft journals have been machined down or if a slightly tighter oil clearance is desired for optimal oil pressure. It's important to ensure your crankshaft has been measured and is compatible with this undersize.

What material are these main bearings made from?

These bearings are made from a high-performance overlay material. This material offers good conformability, meaning it can adapt to the shape of the crankshaft journal to maintain a consistent oil film.

About this part

Product Details

If you're rebuilding the heart of your Nissan VR38DETT engine, King Engine Bearings offers a solid option with their pMaxKote Performance Main Bearings. This set is specifically sized at 0.25mm undersize, crucial for engines that have been machined or require a slightly tighter clearance for optimal oil pressure. King has been a well-known name in engine bearings for a long time, and these are built to handle the demands of performance applications.

What sets these bearings apart is the pMaxKote coating. This advanced surface treatment is designed to reduce friction and improve wear resistance, especially during the critical break-in period and under high-load conditions. The bearings themselves are made from a high-performance overlay material that offers good conformability to the crankshaft journal, helping to maintain consistent oil film thickness. This is important for keeping your engine running cool and preventing premature wear.

This set includes all eight main bearings needed for a complete engine rebuild. When installing, it's always best practice to follow the manufacturer's specific torque and oil clearance guidelines for your VR38DETT to ensure these bearings perform as intended and contribute to a long-lasting engine build.
