Jims Piston Ring End Gap Tool for Harley-Davidson Twin Cam 95-110 3.875-4.000 bore 3200

Piston ring end gap is critical to engine longevity—too tight and you risk ring binding; too loose and you lose compression and blow-by control. The JIMS Piston Ring End Gap Tool 3200 eliminates guesswork by ensuring consistent, accurate measurements across all ring types, so you can build engines with confidence. Whether you're a professional engine builder or a dedicated DIY mechanic, this precision tool pays for itself in saved rework and failed builds.

The flanged design seats rings squarely in the bore, preventing measurement errors caused by ring tilt or misalignment. Its unique key slot provides clear visibility of the gap while you work with your feeler gauge, making measurements repeatable and reliable every single time. Built to last with precision engineering and U.S.A. manufacturing, this tool becomes an indispensable part of your engine assembly process.
