Checkered Flag Performance 3.780 Tapered Piston Ring Compressor

This thing is amazing. Made my build problem free.

A+

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

Worked perfectly on LS 5.3 Vortec rebuild.

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.

Super easy to install pistons.

Good tool , excellent saler ! A++

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.

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!!

Great for the 4.8 ls
