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

The '+1.0mm' indicates that these bearings are 1.0 millimeter larger in diameter than the standard size. This is used when the engine's crankshaft has been machined down (ground) by 1.0mm to remove wear or damage, and needs a slightly larger bearing to achieve the correct clearance.

What is the construction of these main bearings?

These bearings feature a bimetal construction with an aluminum base. This design helps with heat dissipation and provides a durable surface for the crankshaft to rotate against during engine operation.

Do these bearings come with installation hardware?

This product is for the main bearing set only. Installation hardware, such as main bearing cap bolts or crankshaft seals, is typically sold separately and not included with this set.

About this part

Product Details

King Engine Bearings is well-known for making solid engine components, and this main bearing set is a good example of their work. If you're rebuilding the bottom end of your 1995-2004 Toyota Tacoma, or any of the other compatible Toyota models like the 4Runner, Previa, or T100, this set is designed to get your engine running smoothly again. These bearings are specifically for the 1Rz engine and come at a +1.0mm size, which is important if you're dealing with a worn crankshaft that's been machined to that size.

Built with a bimetal construction that uses an aluminum base, these bearings offer good performance for everyday driving. The aluminum base helps with heat dissipation and provides a solid surface for the crankshaft to rotate against. This set is a direct replacement for your original main bearings, making installation straightforward as long as the crankshaft is prepared to the correct +1.0mm size.
