    67445 - Proform Tapered Ring Compressors is rated 4.0 out of 5 by 7.
    Rated 5 out of 5 by from Good product I bought a set of these ring compressors to replace a worn out band type, after sanding a little coating off the lower inside edge these worked flawlessly. I could literally push the pistons in with my thumbs. Although compared to the old band style these seem a little pricy but they saved me time and preformed beyond my expectations. If you are looking for a good ring compressor I would recommend getting these!

    Rated 5 out of 5 by from Works great! A MUST for narrow piston rings! Only assembled one engine with it so far, but works great.

    Rated 2 out of 5 by from Maybe, maybe not. Was unable to use this ring compressor on my build. The rings wouldn’t transfer from the compressor to the block without popping out in between. Maybe if I had a bit more chamfer on the cylinder bores the lip on the compressor may have nested better to the block.

    Rated 1 out of 5 by from No good Couldn't get it to work properly thought it might have just been me had 4 other mechanics try it could not get even one piston to go into block the ID of it is larger than bore allows oil rings to expand before entering block
