About this part

Product Details

These main bearings are built with a bimetal construction, using an aluminum silicon base. This material choice helps them handle the heat and stress inside your engine. They are specifically sized at +0.75mm, meaning they are 0.75mm larger than standard, which is useful when the crankshaft journals have been machined down during an engine rebuild.

This set is made for Ford engines like the R6A, 1.9L (114ci), and 2.0L (121ci) found in models like the Escort, EXP, Lynx, Tracer, and Focus. When you're rebuilding an engine or replacing worn bearings, getting the right size is crucial for proper oil clearance and long-term durability. King Engine Bearings is a well-known name for engine components, and this set is a solid option for getting your engine back in good running order.
