Eastern Tools & Equipment KDT-912 GM 8-Cylinder Valve Spring Compressor

The Eastern Tools & Equipment KDT-912 is a heavy-duty valve spring compressor engineered specifically for servicing GM 8-cylinder engines. This tool allows technicians to remove and replace valve springs and valve guide seals without removing the cylinder head from the engine, saving significant time during engine repair and maintenance.

The compressor is operated by removing the rocker arm and fastening the tool to the stud with a nut, then pulling the handle to compress the spring with controlled, precise force. At 12-1/2 inches in length, the streamlined profile fits easily into confined engine compartments. The black steel construction provides durability and corrosion resistance for long-term shop use.
