I thought the price was right, so I decided to buy a "professional" type of tool for compressing/exchanging the springs on my 1957 Chevy. I had read a number of articles about how to build your own DIY spring compressor with a 2-foot piece of threaded rod, washers, nuts, and an eye bolt. I thought it would be safer to use a "proper" spring compressor so I bought this item.

This spring compressor didn't work so well -- it kept letting go of the spring when the spring was under tension. The instantaneous inadvertent release of a compressed front coil spring created a very scary BANG! and presented a safety hazard. I consulted several others about proper technique for using this tool, and several mechanics advised me that the threads on the tool needed to be kept well greased. I did that. I was also told that some rubber friction material should be placed between the arms of the spring compressor and the spring to keep the tool from jumping off of the spring. I did that too. I used the spring compressor for several hours, and I was never successful. Every time that the spring was compressed under enough tension, the tool would lose its grip and the spring would let go with explosive force. I didn't consider the tool to be safe to use given the performance that I was getting from it, so I abandoned it and looked for another option.

I ended up going to the hardware store and buying a 2-foot section of 1/2"threaded rod, a threaded 1/2" eye bolt, several washers and a few nuts. I built my own spring compressing tool out of a threaded rod and various hardware parts for a total cost of about $6. The threaded rod and washer method was absolutely reliable in compressing the spring. It performed much better than this tool and it only cost about 20% of its price.

If you are interested in buying this tool, I would like to sell you mine.

It works but! Item tends to slip off under compression which could be hazardous. If I needed another one I would spend the money for a better quality one. If you purchase this one please be careful, Because when it came off on me there was no warning.

make a very dangerous job much safer and easier. Use this tool to allow you to put the spring in and seat it properly. Worked very well for me

The ATD spring compressor is a quality item. I used it on the upper limits of its recommended capacity & it performed flawlessly.

Did not have any trouble removing my old coil springs. As suggested, I applied a liberal amount of grease to the threads first, and made sure to position the compressor carefully. Worked without a hitch. Make sure to wear a safety face shield as with all other automotive tools.

I was vary pleased with this tool when used properly this tool griped vary well. The price was ok as well.

Works as advertised, follow the instructions and line it up as instructed and it compressed the spring correctly
