PROFORM 67603 Universal LS-Series Valve Spring Compressor Tool, Head-On Bolt-On Design

The PROFORM 67603 Universal LS-Series Valve Spring Compressor Tool is designed to simplify valve spring removal and installation on GM LS-series cylinder heads. Its head-on, bolt-on design provides a secure connection to the cylinder head, helping maintain controlled compression while servicing valve springs, retainers, and related valvetrain components. This purpose-built tool is suitable for engine builders, professional technicians, and performance enthusiasts working on LS-based applications.
The compressor is manufactured from lightweight aluminum and finished with a durable purple anodized coating for corrosion resistance and easy identification in a busy workshop. Its compact design helps provide access around the cylinder head and valvetrain, supporting efficient service without the bulk of many universal compression tools. The bolt-on mounting arrangement promotes stable operation during installation and removal procedures.
The PROFORM 67603 is supplied as a kit and is intended for use with GM LS-series engines when servicing compatible valve springs. Always verify cylinder head and valvetrain compatibility before use, and follow proper engine service procedures to prevent component damage. The tool is not air restricted and does not require truck freight shipping, making it a practical addition to an LS engine-building tool collection.
