That's gud to know! At least, while it's out of the tower u won't have to be concerned abt it flying out of control. We did one uca shaft on my car and my friend had quite a time getting his compressor hooks between the bottom coils when the top ones were in place. Once he did get them inserted he used his cordless impact to compress the spring. I was wondering abt using the impact, but he does this stuff for a living - so who am I to question. Anyway, still want to do more work on the suspension so this is revelent info.
I used this same one but it seemed like a lot of work to get it out after spring was installed, But I also put in new and found I needed to cut out a coil and just used the lower part and the bolt with a lawn mower blade on top of shock tower and it worked great to pull spring off perch and cut off
It made it easy to paint spring. Also I was able to compress spring from top of shock tower so I had protection from flying springs. There is just enough thread for stock springs so make sure it's fully extended before you start.
With the 4-hook model, you don't need to worry so much about it popping out and heading into the atmosphere. It is pretty much secure, as long as that huge bolt in the middle doesn't snap. With the mustang-II suspension I put in, I pulled off the top hooks, and placed several greased washers on the upper spring mount, and I can compress everything until it comes apart, and cut coils, add new ball joints, or whatever. No mess, no worries, no problems. Kinda hard to see, but the bolt head is on top of the spring hat, and the hooks are down pulling things up where they need to be.
Just an FYI.....I have had the 4-hooks come flying out, with the spring, across the garage....so it can happen. I drop a chain down thru the spring to prevent this.
It is always on cars I part out. The fender is off the car and the engine is usually out of the car. I load up the compressor in the spring, and I stand inside the engine compartment and tighten the compressor. I had a spring come shooting out and go flying across the garage. Good thing I wasn't standing in front of it. So to answer your question, it is a thick chain about 8' long with a chain hook on the end. I drop the chain down through the shock tower down the middle of the spring. I loop the chain around the bottom of the frame and back up in the engine compartment. I hook the chain back to itself. One could still do this with the engine still in the car and the fender still on the car as well.
