    67445 - Proform Tapered Ring Compressors is rated 4.0 out of 5 by 4.
    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.
