COR FAB GM LS Valve Spring Compressor Tool Made in USA

GM LS series valve spring compressor tool allows valve spring changes without removing cylinder heads. Made from Heavy Duty 3/16 thick plate and B7 grade hardware for durability. We provide 2 nuts, 2 washers, and one threaded stud. Replacement hardware is available. Low profile allows use in tight areas where other tools just will not fit. Includes plate and hardware. We recommend charging the cylinder with air to hold valves in place while changing springs. Do not use with heavy dual spring swaps. Made in USA
