Checkered Flag Performance 3.780 Tapered Piston Ring Compressor

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.

The piston ring cup worked great it was a great buy. Thanks for this great product.

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

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 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.

Worked perfectly for 5.3 ls pistons

Great for the 4.8 ls

Super easy to install pistons.

perfect for 5.3

Works excellent for a stock rebuild on a 5.3 ls. Pistons slide right into the block no problem.
