    80521 is rated 4.6 out of 5 by 34.
    Rated 5 out of 5 by from Quality built tool I used this spring compressor for the first time on a 409 chevy engine to replace all valve springs while the engine was still in a 64 Impala. It took a few minutes to get the adjustment correct however it worked flawlessly. I like the feature of the removable handle and that the compressor locks over center so i could use two hands on the valve keepers. Also it works for 3/8 and 7/16 rocker studs. Truly worth the price !

    Rated 5 out of 5 by from well made not a gimmick tool made the job go quickly. you will need a air compressor to assist in the use of this tool. the tool works nice and you can take it apart to work around the master cylinder on number 5 and 7 cylinder. glad to have this tool added to my collection of specialty tools.
