I with you 100% JK-Rubi

I'm hoping TF addresses the issue for future buyers with shorter shocks for this kit. I don't like the idea of adding a spacer to the back to prevent the coil from falling out. Even with the spacer I think the whole setup will still move around under full extension... that concerns me

Stuka

Why? Just add some limiting straps. If you use the shocks to prevent droop, you are just going to snap the ends off. Add a limiting strap to each side to limit droop and you should be fine.

Although, there really should be some clips to hold the spring in place.

So Stuka, are you're saying the 23 Oct 2008 Teraflex instructions should really say, "If the fully extended shock length is longer than 25”, you will need limiting straps (Part # XYZ)."?

If all JK factory coils prings were falling out like this and the fix was to replace the coils or just add spacers, yes I think CJ should bear the responsibility to do so for all vehicles produced, and I suspect that Terraflex would supply free the spacers too any who had previous kits that require them as it is clearly something they should have found when the test vehicle was tested before selling this kit as a production item.

I understand what you are saying but as 99% of all coil sprung vehicles lack limiting straps, even many used in offroad regularly, I don't see the huge numbers of shock failures that should be associated with this.
Spring straps don't "hard limit" droop either they just keep the coils in place, the stetching effect of the spring would take any thump out of the bottom limit and I actually think that is a good thing but still in the end there has to be some hard limit before your tailshaft gets pulled in 2 or brakelines ripped out.
Possibly you mean real axle limiting straps that actually are loops passing under the axle up to the chassis?
We have to remember here these are coil springs, leaf springs self limit travel.
Personally I suspect coils should be solidly attached at both ends so they can handle being stretched as much as they are compressed, because then you could get a vehicle with a lot more travel but still not need ing to be jacked up into the sky in height, so keep the centre of gravity low and cop attention to a minimum while still acheiving good flex.

Thats just it though, we dont know that it is happening to everyone else. We have to assume that he got a complete kit without the spacers prior to the spacers being added, but there is always the chance he got the wrong rear springs, or wrong shocks, or has bad control arm bushings allowing more flex, or has a slightly different build do to factory inconsistency, or whatever reason you can think of. So far he seems to be the only one, or at least one of very few with this issue. I agree that TF made the right decision by adding the spring spacer/guide, but this isnt a part failure either, therfore wouldnt justify a recall/mass mailing of spacer/guides. Now all that being said it would be great to see TF step up and help out there customers by providing these to the people who can provide proof of purchase of a kit that didnt contain them!!!

Stuka

The spring guides will allow for more droop, as the spring will be allowed to drop below the spring bucket. However, if your shocks are bottoming out, a limiting strap should be added to stop the axle just short of bottoming out the shock. This will prevent you from damaging the shock, which can and will happen if you consistantly bottom out the shock.

Hi All,

Maybe this is a dumb question but... what limits articulationin a stock rubicon? I saw no limiting straps or retainers last time I was under there. They would be nice to have and they surely makes sense, but it appears that the stocker and most 2.5 coil lifts rely on the shock to do this.

If some company starts making limiting straps to go along with their 2.5 coil kits I would probably buy them.

Good point Rubicorn ! This is turning into an interesting thread...

The same thing that limits all the coil sprung Range Rovers, Nissan Patrols, Ladas, Landcruisers and every other coil sprung live axle vehicle since the 7o's, the shock absorbers, only vehicle I have ever seen a set of 2" wide limiting straps looped around the axle was my leaf sprung 1968 Army Landrover and they went straight in the bin with no adverse effects.
I suspect coils springs seem to be a new thing over there, us Aussies have been serious into coils since the coil sprung Patrols and Landcruisers hit the market in the late 80's.
