JIMS Twin Cam Piston Ring End Gap Tool

Introducing another unique JIMS tool by master tuner and multiple land speed world record holder Hiro Koiso. Designed to test ring gaps with a unique proprietary cutout feature, the flanged shape allows the piston ring to fit squarely into the cylinder bore every time. Simply install the tool into a 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-inch H-D engines with 3.875 or 4.000-inch bore and 120, 131, and 135-inch JIMS engines with 4.125 or 4.310-inch bore.
