Checkered Flag Performance 3.780 Tapered Piston Ring Compressor

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!

Great for the 4.8 ls

Used this on my LM7 rebuild. I use stock sized pistons and rings and this tool made installing the ringed pistons into the cylinders a breeze. HIGHLY recommend. Personally prefer this over the adjustable compressors as you know you wont be making it too tight or too loose. Obviously the only trade off is having to buy an individual compressor for each engine build assuming you have different cylinder sizes on your other builds.

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

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.

Makes piston install very easy! Fit perfectly. Make sure u order for the correct bore size

The quality looks good I havent used it yet but it looks good and sturdy

This thing is amazing. Made my build problem free.

Worked perfectly. Easier than the old school band clamp style. No hung rings. A little atf to lube the inner surface and tapped right in.

Good investment. Saves so much time.
