Great quality and precision. Pistons dropped in like buttah. I bought this to replace a cheaper one that I had bought off that jungle site. That one had a rough texture and ended up snagging a ring. This one from Speedway is by far superior.

This thing worked amazing. Tried big brand coil style compressors and ended up messing up my oil seperator ring. This works perfectly.

I was afraid that the clamp wouldn't be strong enough, but I was pleasantly surprised that It worked flawlessly on my 5.3 that was bored .020 over. Highly recommend if your pistons are slightly over stock.

Product saves lots of time and money.

Ajust on a piston so it slides though with little pressure and your set for an easy job. Most ring compressor have a tendency to let the rings jump out just before they enter the block. Done 3 engines with this so far and hasn't happened once yet.
