King Engine Bearings Cummins 6Bt/6Bta/6Btaa (Size +0.50mm) Main Bearing Set

Built with a bimetal aluminum silicon base, this main bearing set from King Engine Bearings is specifically made for Cummins 6BT, 6BTA, and 6BTAA engines. These bearings are a +0.50mm oversize, meaning they are designed to be used when the crankshaft journals have been machined down by 0.50mm during an engine rebuild. This size helps restore proper clearances and oil pressure in engines that have experienced wear.

King Engine Bearings uses a tri-metal design with a strong aluminum silicon overlay. This construction is known for its durability and ability to handle the high loads and temperatures found in heavy-duty diesel engines like the Cummins. The specific bimetal composition helps ensure good oil retention and wear resistance, which are critical for the longevity of your engine's rotating assembly. If you're rebuilding the bottom end of your 2005-2008 Dodge Ram 3500 with a Cummins engine, these bearings are a solid option to ensure proper fit and function.
