Checkered Flag Performance 3.780 Tapered Piston Ring Compressor

Worked perfect

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

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

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!

Works as it should, makes the job fast and easy

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.

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!!

This thing is amazing. Made my build problem free.

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!

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