Checkered Flag Performance 3.780 Tapered Piston Ring Compressor

Super easy to install pistons.

This is the king of ring installers , no more fighting the compressed style . Slide in from bottom , and can actually tap pistons in cylinder by hand.

One of the best investments I’ve made.

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

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.

This thing is amazing. Made my build problem free.

Worked perfectly on LS 5.3 Vortec rebuild.

Works great, thanks
