This FA/FB Valve Spring Compressor Tool builds on a proven EJ-platform design and features a newly developed single-piece FA/FB head plate, allowing efficient and secure valve spring service across multiple Subaru engines.

With one plate installation per head, this tool provides full access to all valves and can be used with the cylinder head on the bench or while installed on the vehicle. Designed to eliminate the risks associated with universal clamp-style compressors, it delivers controlled, damage-free operation even with upgraded performance valve springs.

Officially approved by GSC Power Division for use with both standard and beehive valve springs, this tool is ideal for professional engine builders and enthusiasts performing top-end service or upgrades.
