This billet aluminum LS valve spring compressor is universal, compact, 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 is guaranteed to get the job done as easy, if not easier, than expensive compression tools. Quick tip: Instead of stuffing rope through the spark plug hole to prevent your valve from falling, use the Proform Air Hold Adapter Set with an air compressor to do the job properly. Sold Individually.
