Checkered Flag Performance 3.780 Tapered Piston Ring Compressor

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!!

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.

This thing is amazing. Made my build problem free.

Worked perfectly for 5.3 ls pistons

Worked perfectly on LS 5.3 Vortec rebuild.

Junk

These are inexpensive enough for the shade tree mechanic to own even if you only do 1 motor. I have used the universal ratcheting band type and have cut both hands. This tool makes installing pistons a breeze.

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!

Perfect

Works great best money spent on a ring compressor
