Where can I buy this? Does it retain the top AND bottom of the spring? My TF coils already have a large washer on the bottom keeping them in place.

- Add the TeraFlex 1/2" rear spacer with the "spring guide" to prevent the coil from sliding out again.
The only reason I don't like this option is because I finally got the JK's stance the way I like it after moving from the 2.5" BB to coils and adding a front spacer to compensate for front end sag. I'd hate to recreate the factory rake that I finally got rid of.
- Get shorter rear shocks (these 9550 shocks expand to 28.09"). TF even suggested throwing on the original Rubi shocks with TF shock extensions...not sure how that expanded length would compare to the 28.09" that the TeraFlex 9550's stretch to, I'll have to look into that.
- Use a limiting strap. (Although I know it's been used I personally don't like the sounds of this solution)
Any thoughts
You can use the 1/2" spacer without the stock isolator and your rake will not change at all. I needed an extra 1/2" lift in my rear due to a rear metal bumper so I used the stock isolator and the spacer. You can see pics of it here: https://www.jk-forum.com/forums/jk-write-ups-39/notes-teraflex-2-5%94-spring-lift-51483/#post653349

If you are using the wrong shock for whatever reason that may be, then the proper fix is to use the correct shock.
If you are using the recommended shock, IMO what you have is a spring that was not properly designed for the application.
When designing a spring lots factors have to be considered, one of them is called "free lenght". Free lenght is the lenght of the spring when not loaded, out of the vehicle. That lenght should be the minimum lenght needed for the spring to stay in place when the suspension is at full droop, maybe a little more, clearly not the case with this spring!!!!!!

Well that just may be the case, at least for this 2.5" coil lift where the rear coils actually provide just over 2" of lift.
The TeraFlex catalog indicates that the same shocks are used for the 2.5", 3" and 4" kits and has an extended length of 28.09" which may just be too much for this 2.5" coil kit.
So I guess I need rear shocks where the extended length is no more than 26.5" ?
Am I correct is saying that factory shocks plus extensions would have an extended length of about 24" as another option

Did you get the TF 9550 shocks with the kit or are you using your factory Rubi shocks with extensions ?

I was looking at the install instructions and this is what is said in them..
So the instructions tell you to use the Spring Guides in the back.. I will give them a try first since I already have them... If they don't work, then I will look at the Currie spring retainers.. Go with the cheapest solution first then work your way from there..

Here's what the rear coils look like with the Jeep up on a lift and also what we had to do to keep the coils straight as we lowered the Jeep off the lift since the coils were not contacting the spring buckets...
We needed to guide the coils in place as the lift was lowered to keep them straight and centered in the spring bucket since they were not making contact.
