What does '.50mm oversized' mean for these bearings?

This means the bearings are slightly larger than standard size. They are intended to be used when the crankshaft journals have been machined down by 0.50mm to ensure a precise fit and proper oil clearance.

What is the benefit of using high-performance rod bearings?

High-performance bearings are built with materials and designs that can withstand higher loads and temperatures than standard bearings. This is important for engines that are modified for more power or are subjected to demanding use.

Do these bearings come with assembly lube?

This kit includes the rod bearings only. It is recommended to use a quality engine assembly lubricant when installing these bearings to ensure proper oil flow and protection during initial startup.

Product Details

You get a full set of high-performance rod bearings in this kit, which means one box handles a critical part of your engine rebuild. These ACL bearings are built to handle the extra stress that comes with performance engine builds or just keeping a well-loved engine running strong. They are .50mm oversized, meaning they are designed to be used when the crankshaft journals have been machined down by .50mm to clean them up or to achieve a specific clearance. This is a common step when rebuilding an engine, especially if there's any wear on the original crank.

ACL has been around for a while and is known for making well-built engine components. These bearings are made with a specific material composition that helps them withstand higher loads and temperatures compared to standard bearings. When you're putting an engine back together, especially one that's going to see more than just daily driving, getting the bearing clearances right is crucial for oil pressure and longevity. These bearings offer a solid option for achieving those precise clearances with a .50mm undersized crank.

This set is designed to fit a range of popular 1.6L and 1.8L Mazda engines, as well as some Kia and Mercury models that share similar engine platforms. Make sure to check the fitment details to confirm they're the right match for your specific vehicle. When installing, always follow the manufacturer's recommended torque specifications and use a quality assembly lube to ensure proper oil flow from the start.
