Universal Car Valve Spring Remover Installer Compressor Tool Kit Complete service tool kit for installation and removal of valve springs without removal of the cylinder head from the engine. Packaged in molded plastic carrying / storage case. This tool has been developed to remove and install the valve spring with the cylinder head still on the engine and in the car, or with the cylinder head removed. The multi-point adjustable base of this tool bolts securely to the head while the adjustable lever mechanism pivots from the bar thus compressing the spring. Quick removal and installation of the spring retaining keepers is then easily accomplished through the large openings on both sides of the compression tube. This quality tool comes complete with an "easy grip" handle and a storage tray.
