This LS valve spring compressor is compact, is activated with normal hand tools, and takes up almost no space in your toolbox. It will cut valve spring removal and replacement time to around 1-hour. And, it’s guaranteed to get the job done as easy, if not easier, than expensive compression tools.
Instructions can be found in document tab above.
Note: Will only work with Cathedral port LS style heads. Will not work with L92, LS3, LS7 style rectangle port heads
