Checkered Flag Performance 3.780 Tapered Piston Ring Compressor

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!

Good investment. Saves so much time.

Makes piston install very easy! Fit perfectly. Make sure u order for the correct bore size

Perfect

A awesome tool and well worth the money if your rebuilding a 4.8l or 5.3l ls engine.

Worked perfectly on LS 5.3 Vortec rebuild.

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!

A+

Worked perfectly. Easier than the old school band clamp style. No hung rings. A little atf to lube the inner surface and tapped right in.

Made installing the pistons in my 5.3 lm7 a cake walk. The top starts off wide and when you push the piston down it gradually closes the ring gap to fit in the bore. Yes Ill probably only use this 2 or 3 times MAYBE, but it is worth the 20 bucks to compress the rings down to fit easliy
