King Engine Bearings

Does your engine need to hold together as revs, boost and power go up? Bearings are a small part with a big job: they carry the crankshaft and connecting rods and keep the oil film where it belongs. King Engine Bearings makes main and rod bearings, thrust washers and cam bearings for both stock engines and built performance engines.

Engine bearing specialists

King Engine Bearings is a brand that specialises in one thing: plain bearings for combustion engines. The range covers a very large number of engines, from everyday passenger cars to motorsport. Alongside bearings for standard rebuilds, there are performance series with reinforced bearing material and coatings developed for higher loads, higher temperatures and brief periods of low oil pressure. That is why King is used both by engine rebuilders and by people building engines for the street and the track.

King Engine Bearings’ key products

Main bearings and rod bearings are the core of the range and come in standard size as well as oversize and undersize, so they can be used after the crankshaft has been ground. The performance series feature coatings that add protection at start-up and under hard use. You’ll also find thrust washers that control the crankshaft’s end play, and cam bearings for engines with bearing shells in the block. Bearings are usually sold as sets for one engine. See each product for engine code and size.

Frequently asked questions

What do oversize and undersize mean for bearings?

When a crankshaft is ground, the journals get smaller. Undersize bearings, for example 0.25 mm, are thicker and fit the ground journal so the correct bearing clearance is kept. See the size on each product.

When should I choose performance bearings over standard ones?

If the engine gets more power, higher revs or sees track use, performance bearings with reinforced material and coating add an extra safety margin. For a normal rebuild, standard bearings are often enough.
