This is the only tool you need for the job. it pulls the spring evenly like a panel button so you won't damage it. Because of its design it will work in both directions (top or bottom of spring). It is easy to use, lightweight and durable. It is a must have tool for any racing tool box.
Simply hook the spring, set the adjustment on the stud and twist the knob in or out to set spring tension. These are great for body panels, tin work or oil pan windage trays.
Perfection every time!!!
