Description of Master Strut and Coil Spring Tool: Tool Aid SG 62900 - The Strutter Macpherson Strut Coil Spring Tool
For use on the MacPherson Strut Assembly found on virtually all modern domestic and imported vehicles. Use with impact wrench or hand tool, ON or OFF the car. Contains complete instructions and a safety kit. The one piece cold headed bolts are made of chromium-molybdenum alloy steel.
Good quality; worked great. I recommend using "j" safe hooks when using them. They work well with already compressed springs; not long enough when trying to compress the new springs.
Pros
Solid chrome molybdenum alloy steel cold head screws
