What does the +0.5 size mean for these bearings?

The '+0.5' indicates that these bearings are 0.5mm larger in diameter than standard size. They are used when the engine's crankshaft journals have been machined down by 0.5mm during an engine rebuild to ensure a proper fit and oil clearance.

What kind of engines are these bearings best suited for?

These bearings are designed for low to medium-load engines. They feature a lead-free composite and bi-metal aluminum construction that works well in applications that aren't subjected to extreme stress or high RPMs.

Are these bearings compatible with all engine types?

No, these specific bearings are designed for Ford, Kia, and Mazda engines that are DOHC 16-valve, SOHC 16-valve, or SOHC 8-valve. It's always best to confirm your specific engine configuration before purchasing.

About this part

Product Details

What you get here is a set of King Engine Bearings rod bearings, specifically sized at +0.5mm. These are designed for a range of Ford, Mazda, and Mercury vehicles with DOHC 16-valve, SOHC 16-valve, or SOHC 8-valve engines. King has been specializing in bearings since 1960, focusing on making them well-built and reliable.

These bearings use a lead-free composite material that's environmentally safe, making them a good choice for engines that aren't under extreme load. The bi-metal aluminum construction is also notable for its performance in these types of applications. Because they're a +0.5mm size, they're intended for use when the crankshaft journals have been machined down by 0.5mm during an engine rebuild.

This set is a solid option for many popular vehicles like the Mazda Miata, Ford Escort, and Mazda Protege. If you're rebuilding an engine and need bearings that fit right and perform reliably for everyday driving, these are worth a look.
