Review KING ENGINE BEARINGS Mazda Am series Pairs Main Bearing Set fits MIATA 1990–2005

The MB5304AM engine bearing set is an essential upgrade for Mazda Miata (NA) vehicles from the years 1990 to 2005. These bearings are specially designed for use in the AM-series engines, ensuring a perfect fit and optimal engine performance.

This set includes not one, but four high-quality engine bearings: two main bearings, one rod bearing, and one crankshaft bearing. Each bearing is meticulously crafted with advanced materials, including a chrome steel outer race, brass inner race, and a nitrided steel pin. These materials provide enhanced strength, durability, and resistance to wear, keeping engine components running smoothly for thousands of miles.

The MB5304AM main bearings have an improved design, featuring enlarged oil squirters that promote consistent lubrication and cooling of the bearing surfaces. This results in reduced friction, lower temperatures, and fewer oil leaks. Moreover, the enlarged oil squirters allow for increased oil flow, ensuring that the engine stays well-oiled for optimal performance.

The rod bearings in this set have a a higher quality seal design to help prevent oil leaks. The OEM rod bearings are known to sometimes leak oil during high-RPM usage or extended periods in high-heat conditions. The MB5304AM rod bearings address this issue by providing an improved seal, keeping engine oil contained and ensuring an efficient oiling system.

The crankshaft bearing in the MB5304AM set is manufactured with a premium grade of alloy steel, providing exceptional load-bearing capacity and resistance to deformation under pressure. Additionally, the bearing includes upgrade API-614 features such as increased oil clearance and improved oil flow through larger oil gaps. This leads to better lubrication and reduced wear, making your engine run more smoothly and efficiently.

Installing these high-performance MB5304AM engine bearings in your Mazda Miata is an investment in your engine s longevity and reliability. By replacing the original bearings with these premium upgrades, you can rest assured that your engine will not only perform better but will last longer, saving you from costly repairs in the future. If you value the well-being of your cherished Miata, there s no better choice than the MB5304AM engine bearing set.
