This tool is a "must have" for those hardcore motor builders.   Our adjustable piston ring squaring tool fits any cylinder bore sizes from stock 50cc ruckus all the way up to the big bore 232cc GY6.


Simple and easy to adjust by loosening each thumb screw and matching the ring pushers to the cylinder wall size.  The ring squaring tool pushes the piston ring far enough down into the cylinder to clear imperfections present at the top of cylinders, while also allowing your feeler gauges to be able to reach the ring gap to measure.


Maunfactured from lightweight aluminum that won't scratch or mar cylinder decks.
