What does '1.0mm oversize' mean for these bearings?

This means the bearings are thicker than the standard size by 1.0mm. They are designed to be used when the crankshaft journals have been machined down by 1.0mm to remove wear or damage, ensuring a proper fit and oil clearance.

Are these bearings suitable for a stock, unmachined crankshaft?

No, these are 1.0mm oversize bearings. They require the crankshaft journals to be machined down by 1.0mm to match the bearing size. Using them on a standard-sized crankshaft will result in incorrect oil clearance and potential engine damage.

What is the construction of these connecting rod bearings?

These bearings are made with a bimetal construction, featuring an aluminum base. This type of construction is chosen for its ability to handle the high loads and temperatures found in an engine's rotating assembly.

About this part

Product Details

When you're rebuilding the engine in your 1988-1995 Toyota 4Runner, especially with the 3VZE engine, getting the connecting rod bearings right is crucial. These bearings sit between the connecting rod and the crankshaft, allowing them to spin smoothly while handling the immense forces of combustion. This set is specifically sized at 1.0mm oversize, meaning it's intended for crankshaft journals that have been machined down by 1.0mm to clean up wear or damage.

King Engine Bearings uses a bimetal construction with an aluminum base for these rod bearings. This design helps them handle the loads and heat generated during engine operation. Because they are an oversize part, they are meant to be used after the crankshaft has been professionally machined to the correct undersize specification. This ensures a proper fit and oil clearance, which is essential for engine longevity.

If your 3VZE engine build involves machining the crankshaft, this 1.0mm oversize set from King is a solid option to consider for your Toyota 4Runner, Pickup, or T100.
