What is the purpose of the +.026mm sizing?

The +.026mm sizing indicates that these bearings are slightly larger than standard. This is used when a crankshaft has been machined (ground undersize) to correct imperfections or to achieve a specific clearance with the bearing. It's crucial to match the bearing size to the machined crankshaft journal size.

What is the pMax Black material?

The pMax Black material is King Engine Bearings' racing line. It's a tri-metal construction designed to offer enhanced strength and durability under the higher loads and temperatures typically encountered in performance and racing engines.

Do these bearings come with a warranty?
