Checkered Flag Performance 3.780 Tapered Piston Ring Compressor

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!

One of the best investments I’ve made.

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.

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.

Worked perfectly for 5.3 ls pistons

Good finish and great fitment. Ill never use a clamp style again unless its a one time thing. Even let a friend of mine with next to no mechanical knowledge pop a couple pistons in and had no issues.

Great for the 4.8 ls

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!

Worked perfectly on LS 5.3 Vortec rebuild.
