Vehicle Fitment Guide

Notes: 

• Due to factory variations in crankshaft journal and piston gudgeon pin sizes, resizing of the conrod big end and/or small end bush to pin clearance may be required. Have your engine builder check the clearances before assembling and have them set depending on the application.
