Checkered Flag Performance 3.780 Tapered Piston Ring Compressor

This thing is amazing. Made my build problem free.

These are inexpensive enough for the shade tree mechanic to own even if you only do 1 motor. I have used the universal ratcheting band type and have cut both hands. This tool makes installing pistons a breeze.

A+

A awesome tool and well worth the money if your rebuilding a 4.8l or 5.3l ls engine.

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

Good investment. Saves so much time.

The piston ring cup worked great it was a great buy. Thanks for this great product.

Works perfect

used for stock bore pistons, stock size rings with 20 thou gap. never going back to old style ring compressors ever again. used it only once, i will probably never use it again, but il looks good on my shelf. it will save you a lot of headaches!!

Worked perfect
