Checkered Flag Performance 3.780 Tapered Piston Ring Compressor

Super easy to install pistons.

Great for the 4.8 ls

Yes it is bore specific. But you will never install pistons faster than you ever have without it. Fast, easy,great tool for installing stock bore Ls 5.3 pistons.

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.

Worked perfectly for 5.3 ls pistons

This thing is amazing. Made my build problem free.

Junk

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.

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

Works great best money spent on a ring compressor
