As expected - Refreshing	April 7, 2026
Reviewer: MKV from Circle Pines, MN United States

Rare in this day to get a value that turns out as expected. Cylinder casting was fine, as was piston. Used OEM rings, but everything went together smoothly. Fired right up. Time will tell but great so far.

Everything worked as described	December 1, 2019
Reviewer: Anonymous Person

I put the new piston and cylinder in my MS391, everything was correct. Small issue with the threads in the intake manifold mount on the cylinder, fixed with a file.
