JIMS® TWIN CAM PISTON RING END GAP TOOL
Introducing another application specific tool from JIMS® created by master tuner and land speed world record holder Hiro Koiso! This tool is designed to check piston ring gap with a proprietary cutout feature. The flanged shape allows the piston ring to fit squarely into the cylinder bore. Simply install the tool into the cylinder bore and place your piston ring onto the tool. You can view the ring end gap in the "Key Slot" and use JIMS® Feeler Gauge Tool No.908 to determine your exact end gap measurement. JIMS® Twin Cam Piston Ring End Gap Tool works for 95", 103" and 110" H-D engines with 3.875" or 4.000" bore and 120", 131", and 135" JIMS engines with 4.125" or 4.310" bore.
