Overhead Valve Spring Compressor: Universal: Made in the USA

The AT1011 Overhead Valve Spring Compressor creates an easy way to remove valve spring keepers and springs without removing the cylinder head. The molded comfort-grip handle makes quick spin adjustments. The jaws are spring loaded and offset to grip springs in parallel compression position, and long enough for use on high-performance engines. The compressor jaws are case hardened for increased durability.
