MMonDod Engine Piston Ring Compressor, Auto Installer Removal Tool Set Kits

Worked great; rebuild my engine in a John Deere Gator and this allowed me to compress the rings to get the new pistons installed.

Used for a GY6 go kart engine. Simple to use saved a lot of struggle with the rings

I did not like that the caliper did not help me with the oil rings as they do not hold on to the caliper due to their minimal height, However, for the compression rings it worked excellently.

A bit cheap, but got the job done rebuilding a chrysler big block. The ring compressor worked as it should and the ring pliers also worked, but I suspect if the ring gaps were tighter, it would've struggled on the big diameter pistons (4.380"), for smaller pistons, these will work just fine.

Worked good, it is a little bit of a pain to use but once you get the hang of it it's not bad. Helped me rebuild my first engine!

Absolutely horrible, tried 2 different ones, both were bent, both scratched my block, scratched my piston skirt, and sliced my hand in 2 places, what a cheap piece of crap, I should file a lawsuit for even having this for sale

Good quality

made the rebuild go so much smoother
