What does the +0.25mm size mean for these rod bearings?

The +0.25mm designation indicates that these bearings are slightly larger than standard size. They are intended for use when the engine's crankshaft journals have been machined down by 0.25mm during an engine rebuild to ensure a proper fit and oil clearance.

Are these bearings suitable for high-performance or racing engines?

These bearings are designed for low to medium-load engines. While well-built, they may not be the best choice for extreme high-performance or racing applications that place significantly higher stress on engine components.

What is the material composition of these bearings?

The bearings are made from a bi-metal aluminum material. They also incorporate a lead-free composite, which is an environmentally safe material choice for this application.

About this part

Product Details

If you're rebuilding the engine in your 1993-1997 Toyota Corolla, these rod bearings from King Engine Bearings are a solid option. They are specifically sized at +0.25mm, meaning they're designed to be used when the crankshaft journals have been machined down by that amount during an engine rebuild. King has been specializing in bearings since 1960, focusing on making high-quality engine components.

These particular bearings are made with a bi-metal aluminum material and feature a lead-free composite. This construction makes them ideal for engines that operate under low to medium loads, which is common in many daily-driver applications. They are well-built to handle the stresses of connecting rod movement against the crankshaft.
