What does 0.25mm undersize mean for these bearings?

This means the bearings are manufactured to be 0.25mm smaller in diameter than standard size. They are intended for use when the connecting rod journals on your crankshaft have been machined down by 0.25mm to correct wear or ensure a clean surface.

What is a trimetal bearing?

A trimetal bearing is constructed with three distinct layers of materials. This multi-layer design helps to optimize load capacity, wear resistance, and the bearing's ability to conform to the crankshaft surface, which is important for engine longevity.

Do these bearings come with installation instructions?

While this set includes the connecting rod bearings, it's recommended to refer to the manufacturer's official installation guide or a reputable service manual for proper installation procedures and torque specifications.

About this part

Product Details

In this box, you get a set of King Engine Bearings connecting rod bearings, specifically sized at 0.25mm undersize for the Toyota 3SGTE engine. These are trimetal bearings, meaning they're built with multiple layers of different metals to handle the demanding conditions inside your engine.

When you're rebuilding or refreshing the bottom end of your 3SGTE, especially in your 1988-1993 Toyota Celica or 1991-1995 Toyota MR2, properly sized and well-built connecting rod bearings are crucial. These bearings sit between the connecting rod and the crankshaft, allowing them to spin smoothly while handling the immense forces generated during combustion. The 0.25mm undersize means these are intended for use when the crankshaft journals have been machined down by that amount to clean them up or correct wear.

King Engine Bearings is a well-known name in the performance and racing world, and these trimetal bearings are a solid option for anyone looking for reliable internal engine components.
