Piston Ring End Gap Chart

Piston Ring End Gap Chart - To determine the initial gap, position the ring inside the cylinder near the top of the bore. 4.000” bore street engine with cast piston the top ring end gap factor is.004”, thus 4.000” x.004” =.016” minimum end gap. Web to use this chart, multiply the bore size by the ring end gap factor to obtain the minimum end gap which should be achieved. Web setting the correct ring gap on aftermarket piston rings is crucial for proper performance and engine longevity. Use this chart to determine the proper end gap for your engine. These are based on different user applications. Web use a feeler gauge to measure the exact clearance. (bore size measured in inches). Expander ends must not overlap. Web install the lower steel ring, the ring end gap must be approximately 90° to 120° left from the expander edges.
