What does the '+0.5' size mean for these main bearings?

The '+0.5' designation indicates that these bearings are 0.0005 inches larger than the standard size. This is typically used when the crankshaft journals have been machined down to correct for wear or damage, and these bearings help restore the proper oil clearance.

What is the benefit of a bimetal aluminum silicon construction?

A bimetal construction combines the strength of steel with the low-friction and heat-dissipating properties of an aluminum silicon alloy. This design helps to reduce wear and manage engine temperatures effectively, contributing to the bearing's durability.

Are these bearings suitable for a performance build?

While these bearings are well-built for their intended application, they are designed as a direct replacement for the stock engine. For high-performance or heavily modified engines, it's always best to consult with a specialist to ensure the bearing specifications meet the demands of your specific build.

About this part

Product Details

Built with a bimetal aluminum silicon base, this main bearing set from King Engine Bearings is designed for the 1991-1994 Lincoln Town Car equipped with the 4.6L V8 Romeo engine. These bearings are crucial for supporting the crankshaft within the engine block, ensuring it spins smoothly and with minimal friction. The specific +0.5 size indicates these are intended for engines that have already undergone some machining or wear, requiring a slightly larger bearing to achieve proper clearance.

King Engine Bearings uses a bimetal construction, which combines the strength of steel with the low-friction properties of aluminum and silicon. This combination helps to manage heat effectively and resist wear, which is essential for the longevity of your engine's rotating assembly. This set is specifically sized at +0.5, meaning it's designed to fit crankshaft journals that have been machined down by 0.0005 inches, ensuring a precise fit and optimal oil clearance in engines that have seen some use.
