The Piston Ring Square Tool 108.0mm – 115.0mm is an essential precision instrument for engine builders and experienced mechanics performing top-end overhauls or complete engine rebuilds. This tool is specifically designed for working with pistons in the 108 to 115 millimeter bore range, ensuring proper ring installation that is critical to maintaining compression integrity and oil control.
Engineered by ARP, a trusted name in fastening technology, this piston ring square tool features precision dimensions that accommodate various ring widths and piston configurations. Its design prevents the common mistake of forcing rings in at an angle, which can lead to damage. By holding the ring perpendicular to the piston bore during installation, the tool ensures even distribution of insertion force, making the job faster and more consistent.
Professional engine builders, rebuilders, and serious performance enthusiasts will find this tool invaluable for any build involving pistons in this bore size window. Whether restoring a classic engine or assembling a high-performance build, this tool enhances the installation process and contributes to long-term engine durability.
