What does the '+1.0mm' sizing mean for these bearings?

The '+1.0mm' designation indicates that these bearings are oversized by one millimeter. They are designed to be used when the crankshaft journals have been machined down by 1.0mm, typically during an engine rebuild to correct wear or damage.

What is the advantage of a bimetal aluminum base bearing?

Bimetal bearings, especially those with an aluminum base, offer good conformability and embeddability. This construction helps them adapt to slight imperfections in the crankshaft surface and can embed small debris particles, reducing the risk of bearing damage.

Are these bearings sold individually or as a set?

This product is a set of connecting rod bearings. It includes all the necessary bearings to replace the connecting rod bearings on a single engine for the specified Toyota 1RZ application.

About this part

Product Details

These King Engine Bearings connecting rod bearings are built with a bimetal construction, using an aluminum base. This design is important for the smooth operation of your engine's rotating assembly. They are specifically sized at +1.0mm, meaning they are intended for engines that have had their crankshaft journals ground down by 1.0mm during a rebuild or repair.

This set is designed for the Toyota 1RZ engine, which can be found in various Toyota models including the Tacoma, 4Runner, Previa, and T100. When you're rebuilding an engine or addressing worn rod bearings, choosing a well-made bearing set like these from King Engine Bearings ensures that the critical interface between the connecting rod and crankshaft is properly supported. This helps maintain oil pressure and reduces friction, which is key to engine longevity.
