Checkered Flag Performance 3.780 Tapered Piston Ring Compressor

Ill never use the old style again. Worked great

Good tool , excellent saler ! A++

This thing is amazing. Made my build problem free.

Works perfect

Perfect

perfect for 5.3

Works great best money spent on a ring compressor

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!

If you have a set bore you are working with, this tool is amazing to use. Soo much better then any adjustable one I have used in the past. It was so easy, I thought something was wrong.

Yes it is bore specific. But you will never install pistons faster than you ever have without it. Fast, easy,great tool for installing stock bore Ls 5.3 pistons.
