Checkered Flag Performance 3.780 Tapered Piston Ring Compressor

Works perfect

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

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

Just finished installing all 8 pistons on my 5.3l build. Works great and is easier to use than the adjustable band style. Only down side is if you change bore size you have to buy another one relating to the new bore size. But, at $20, its worth it. Great tool!

Ill never use the old style again. Worked great

Super easy to install pistons.

Works as it should, makes the job fast and easy

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.

Perfect
