Good for the shade tree, Mechanic
What you would need for a building your engine a few times. A professional will likely get a different one for longevity. But mine is still working good after three uses.

Doesnt evenly clamp rings all the way around the piston but did the job anyway.
This ring compressor does work but the tension screw region tends to bow out a little bit so you gotta be careful when putting in pistons with this tool to not break a ring.

I’d spend a little more and get a sturdier one.
It did its job for the one cylinder I had to redo. I’d hate if I had to do more than one though. This thing is kind of flimsy.

Seriously Can’t Beat the Price/Wuality
Rebuilt a SBC and both the compressor and expander worked well. My tip is to oil up the inside of the compressor well, make sure it’s “square/equal” on all sides of the piston. The expander isn’t as well made, but it does work pretty good once you get the feel of it.

Great quality great price
Surprising quality for the price, thick and durable and held the rings on my Cummins no problem. Stands up to my snap on at work and not even half the price
