In fact, yes. It is necessary to adjust the position a little. If you remember to watch the compression of the spring, you will see what we mean. This is a good solution
I think so, though I'm not certain if the threaded bolt (rod) has the same pitch. It might be easier to simply get a matching bolt (long one) with the right pitch, then use a matching nut to screw down the follower to take the tension off the retainer locks, easy!
I have created this tool for ls engineers, but it is bad for 4 users. Three models of the six
Newer heads probably use the same size of thread for rocker boss bolt holes, so this should work on them as well. Other than the spring and retainer, the spring is the same

I agree with others that this thing works great for the money and is exactly what it has to be. I don't think the stud, washers, and bolt are even of good quality and am concerned they won't last very long. It's been over a week since I removed my springs, but I have not yet put the new ones on. I have chewed holes in the stud, the washers are distorted, and the nut has threads hanging We want to be able to use this device more than once, so just spend a little more money and charge us an extra $5. In the future, I will have to source a new grade 8 system if I plan on using this two or more times. Up to date
It only took me a couple of minutes to install springs on one head before the stud, nut, and washers fell apart. It should be pointed out that this is a one-time use tool that only works with stock springs. This is garbage.
I've pulled out only one set of springs and the threads have already developed significant wear. The tool does not struggle under the strain of monster springs. The stock LQ9 springs have been replaced with LS6 springs. There is no difference in the seat spring rates between the two sets. Make sure all surfaces are properly greased when using to make sure friction and wear are reduced. In my opinion, it is only worth your consideration if you are planning to use it just a few times. It is true that Lisle offers a warranty, but you need to factor in the time, effort and shipping costs involved.
The reviews for other people saying that the threaded shaft had broken between the second and third pair of springs they compressed were of no concern to me because I was willing to buy another fastener. So far I have taken apart and put together three pairs of heads, and the tool has been an absolute pleasure to use. It's just a matter of keeping the threaded shaft oiled through the whole process while removing and installing the springs, and I use the brass nut that comes with it as the main nut.
Just be sure to add an extra stud. It's just fine. Just be sure to add an extra stud. Despite their popularity, local hardware stores don't carry metric bolts that are threaded all the way through. There is one here, so find one. Having said that, I was able to switch out all 16 springs without any problems, but the threads are pretty much It is best to get the tool that compresses two springs at once if you are able to afford it. The products in this category will get the job done if you're on a tight budget like me.
Where the rockers rest in most LS heads, there is a flat spot, but the LS7 is not like that. Rockers on this chair have a round, raised edge seat. Interference with the tool is caused by these edges. In addition, the heads had work done to them before I got the car, and I am unsure if the springs are stock. In spite of this, the springs cannot be compressed enough with this tool. My tool bent so much that I could not use it anymore after getting two out of it.
This is what it's supposed to do. A tumble in an abrasive media could soften the corners so that they would not make an impression on the sealing surface of the heads. It should also be noted that lubricant should be used to prevent galling in the threaded studs.
Works great on Ls Lc9 engine. I'm not sure how many things you can do with it, but I would wager you could get quite a few out of it.
'M8' spring tensioners are much easier and more forgiving to use than the other type that's commonly sold which compresses two springs at once. Just make sure you keep the threads clean as you go and buy a backup. Make sure the bolt you use is 25x20 if the threads become.
