Overview
The Taiho Honda B20 bearing set supplies standard-size (STD) engine bearing shells for the B20B and B20Z bottom end. Taiho is the Japanese manufacturer that produces genuine OE bearings for Honda, so these tri-metal shells are built to match factory fit, oil clearance and durability during an engine rebuild.
Ideal for anyone rebuilding or refreshing a Honda B20 short block who wants genuine OE-grade Japanese bearings instead of generic replacements, restoring correct oil clearance and long-term reliability.
