What does the +0.25mm sizing mean for these main bearings?

The +0.25mm sizing indicates that these bearings are intended for engines where the crankshaft journals or the main housing bores have been machined undersize by 0.25mm. This is common in engine rebuilds where surfaces are reconditioned.

What is PMaxBlack technology?

PMaxBlack is a proprietary overlay material developed by King Engine Bearings. It is a tri-metal copper-based material designed to provide superior load-carrying capacity, helping to protect your engine's crankshaft under demanding conditions.

Do these bearings come with installation instructions?

While this set includes advanced bearing technology, it is always recommended to refer to the manufacturer's official installation guidelines or consult a professional mechanic for proper installation procedures to ensure optimal performance and longevity.

About this part

Product Details

When you're rebuilding the bottom end of your Ford 4.6L engine, you need main bearings that can handle the job. This set from King Engine Bearings is specifically made for the 281 cubic inch SOHC 16-valve engine and comes at a +0.25mm size, meaning it's designed to fit engines that have already been bored out or machined to that specification. King has been a specialist in bearings since 1960, focusing on delivering well-built engine components.

These main bearings feature King's PMaxBlack overlay, which is a tri-metal copper-based material that offers superior load capacity compared to standard bearings. They also incorporate Radialock technology, which helps maintain optimal crush height during installation, ensuring the bearing stays securely in place. This combination of materials and design helps protect your crankshaft and ensures smooth operation.

This set fits a range of Ford, Lincoln, and Mercury vehicles, including models like the Ford Crown Victoria, F-150, and Lincoln Town Car. Make sure to verify fitment for your specific application.
