King Engine Bearings Subaru FA20/ Toyota 4U-GSE/ O/S Housing .005 (Size 0.25) Main Bearing Set

What you get in this box is a set of King Engine Bearings main bearings, specifically sized at 0.005 inches undersize (0.25mm). These are meant for Subaru FA20 and Toyota 4U-GSE engines, often found in performance applications where a detailed rebuild is underway.

King uses their XP high-performance overlay, which is a multi-layer material designed to handle the stresses of performance engines. This overlay is bonded to a steel-backed structure for solid support. The 0.005 inch undersize means these bearings are intended for crankshafts that have been machined down to match this specific size, ensuring a tight and accurate clearance for optimal oil film and performance. This is a common step when rebuilding an engine to factory or improved specifications.
