JEGS 555-80521 Stud Mounted Valve Spring Compressor

Changing valve springs at the track or with the cylinder head on the bench just got easier with the JEGS 555-80521 Sud-Mounted Valve Spring Compressor. Installs on 3/8 in. or 7/16 in. studs (with spring diameters ranging from 1 in. to 2 in.) to compress high-load race valve springs. Includes a 12 in. handle and rubber non-slip grip. For use with heads still on the engine. We recommend JEGS flexible air valve holder 555-W84003 and air hose fittings 555-81812 to keep valves from dropping into cylinders when keepers are removed.
