The Allstar Performance Valve Spring Compressor (ALL96490) is an adjustable C-clamp style tool designed to remove high-pressure valve springs with minimal effort and without slipping off the retainer. It fits most cylinder heads, including Hemi applications.
The spring cup accepts stock springs up to 1.750 inch in diameter, and the tool has a working window of 1.100 inch to access keepers, though this window is too large for some small-diameter spring and retainer combinations. Throat depth is 5-1/2 inch. The compressor uses a 9/16 inch hex for use with a wrench, ratchet or impact, and is rated to handle spring pressures in excess of 1,200 lbs. It is a head-off tool made from steel with a zinc oxide finish.
