Fowler is one of the most trusted names in precision measurement equipment. This affordable micrometer takes precision measurements in the 1″-2″ range with 0.0001″ precision, making it perfect for measuring the main and rod journals of 1ZZ, 2ZZ, 1ZR and 2ZR engines. Some people rely on plastigauge to check their oil clearances during a build but taking precision measurements of all of the parts and calculating the clearance is the best way to get the exact clearance and be sure your engine is built right the first time.
This is the analog model so you must know how to read a micrometer to use it. Look it up online, it’s easy!
