Hey maddawg, I think I can shed some more clear light on this issue. I have both the cheap set and the more expensive set from Harbor Freight. I have used them on a number of passenger cars (I do have a compressor and air ratchet). I did my wife's struts on her Volvo during the summer and had to use both sets to get them to compress evenly. I tried them on one of the Jeep struts just to see how they would act and I found that I probably could have "made it work". But I would use a couple of short chains wrapped around the coils to act as safeties just in case one slipped. Now keep in mind that I am pretty comfortable doing this kind of work. That being said, if I needed to do them on my Jeep I would either rent two sets (so you can use four to compress them more evenly) or I would have someone else do them. I would not recommend that you try this with the cheap tools if you are new to this (and I am not any HF). You could rent good ones as inexpensively as you could buy cheap ones. And its not like a pair of pliers that you will use weekly for the next 20 years. Once you get your Jeep done, you will probably not need them again for a long time. Mine collect dust for years sometimes before I need them again.

Very good information there. Spring compressors can be very dangerous but they are also needed in this case. I think mine cost around $40.00 when I bought them 8+ years ago. They are not the expesive ones, but they are not the cheap ones either. I only needed 2 but I could see where 4 would help.
The only reason I said to have a shop help is because of the questions you are asking. A shop can do them pretty fast for you and most of the time its pretty cheap to have them do it and takes away the danger aspect of doing the install. My neighbors shop in Colorado had offered to do them both for $10.00 for me but I am the kind of guy that likes to do his own work.
Its all up to you how you proceed. If you let me know when you are doing your install I will make myself availible by phone to answer any questions you may have. PM me and I will give you my number.
