The important process of gapping piston rings is made easier and more accurate thanks to ARP’s precision Piston Ring Squaring Tools. Setting a ring absolutely perpendicular to the bore is assured through use of the ARP Squaring Tool, which registers on the block deck. This is far more accurate than using a piston or other device that can rock in the bore and place the ring at an angle. Precise end gaps are essential to achieve optimum combustion sealing.
ARP’s Piston Ring Squaring Tools are precision CNC machined from 6061-T6 billet aluminum and black anodized for long-lasting protection. They come in six sizes, with ranges covering bores from 3.150″ (80mm) to 4.800″ (122mm). The sizes are prominently engraved on the tools for ease of selection.
In addition to in-block gapping, the squaring tools can be used in conjunction with ARP’s bore-specific Tapered Ring Compressors to facilitate gapping the rings on a bench for added comfort and convenience. ARP offers Tapered Ring Compressors in over 125 different sizes to accommodate virtually every popular SAE and Metric bore.
