Checkered Flag Performance 3.780 Tapered Piston Ring Compressor

Good tool , excellent saler ! A++

Add some lube set the piston in so the skirts are out the bottom then set in the cylinder sleeve dot on the piston toward the front of the motor and push piston down and tap with a rubber mallet. That easy.

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.

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.

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

Works as it should, makes the job fast and easy

Great for the 4.8 ls

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

Ill never use the old style again. Worked great

Super easy to install pistons.
