JE Pistons Tru-Arc lock wrist pin retainer, carbon steel, 0.927-inch diameter with 0.042-inch lock thickness. Tru-Arc locks are reusable and can be used with stock sharp-edge wrist pins, offering easier installation and reusability compared with some spiro-type locks. JE notes that tru-arc locks fall between wire and spiro types in retention style and are recommended for lower-horsepower applications where reusability and installation ease are priorities.
