LS1 Valve Spring Compressor Tool

These LS Series valve spring compressors are designed for removing the valve springs while the cylinder heads are still attached to the engine. They require the use of an impact or ratchet to compress the springs and allow for the installation of the new spring. These LS Series valve spring compressors are made of heat-treated, precision CNC-machined steel to ensure proper seating on the cylinder head and valve spring retainer. Best of all, you can compress 2 springs at once cutting your install time IN HALF!
