Checkered Flag Performance 3.780 Tapered Piston Ring Compressor

Very well made, had to return, needed the 4 inch size.

Best tool in my box...definitely worth the money!

Have always used a ratcheting style clamp to set pistons in and sometimes have issues where Id have to start over, but with this device the positions dropped right into cylinder with a couple of taps.

Worked perfect

These style ping ring compressors are hands down the best. Totally worth the money and they make installing pistons into cylinders a breeze with the rings installed. The only downside is having to buy for all cylinder configurations. Highly recommend!

Makes piston install very easy! Fit perfectly. Make sure u order for the correct bore size

Just a quick review to say thank you for producing a great quality tool at a reasonable price. I finally did my 5.3 LS rebuild over the weekend and this ring compressor was indispensable. No sliced fingers, no crooked pistons! I will buy another one every time I need to rebuild a different size engine.

Super easy to install pistons.

Works excellent for a stock rebuild on a 5.3 ls. Pistons slide right into the block no problem.

Made installing the pistons in my 5.3 lm7 a cake walk. The top starts off wide and when you push the piston down it gradually closes the ring gap to fit in the bore. Yes Ill probably only use this 2 or 3 times MAYBE, but it is worth the 20 bucks to compress the rings down to fit easliy
