Checkered Flag Performance 3.780 Tapered Piston Ring Compressor

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

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 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!

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.

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!!

Works as it should, makes the job fast and easy
