I am no engineer or suspension guru by any means, but I do have a decent amount of knowledge when it comes to suspensions and their components. It boggles me why the vast majority (ok, almost ALL) of the suspension "kits" out there for a coil sprung vehicle have no limiting straps. I understand it can be a custom type thing (kind of like a bumpstop) so many manufactures would not necessarily want them in their kit. But, I also don't see very many people using them either.

I think for the most part the limiting factor for the suspension droop in the stock JK is the sway bar system. And that is fine... except when off road there are many times that it is disconnected. So then what limits it? Those expensive shocks we just purchased for our new lift? Sounds like a good way to kill a shock fast.

Anybody out there running limiting straps? Post up some pics of what you are using, and maybe some info about them... What brand? How/where do they mount? Any regrets?

 

I am researching the same thing as well. Recently installed a 3.5 re lift and I was testing it out the other day with a fork lift and opposite side spring came out of the lower mount. I will b running them soon

 

I am running the Teraflex kit for the front. I believe it is the 15.5" strap. The top bung welds into an opening in the frame and the lower bolts onto the side of the coil perch. I run a 2.5" lift and it provided me with my opinion, the perfect amount of flex for me. Here are some photos of the straps.

Testing right after the install.

 

Nice, I will have to check those Teraflex ones out.

It seams like I will almost have to get my suspension set up, then measure for the correct length straps once I know where they mount exactly (depending on which ones I go with). I suppose once I get the extended length of the shocks I choose I could kind of calculate it that way also... although I should factor in the max droop of the driveshaft as well, as that could be the limiting factory apposed to just the shocks.

Sounds like a trial and error thing. Probably why most kits don't come with them.

 

There are many factors to consider when using limit straps, as well as deciding if you even want to use them at all. I run them in the rear because my shocks are mounted inboard of the frame, and when my tires droop, the opposite shock moves outward and will rub on the frame.(I will correct this in the future with a little extra grinding and notching) But other set ups might find their stuffed wheel angles too hard and the inner portion of the tire will rub in the wheel well or against the frame. Or, your drive shaft might bind at full droop. I'm running King 2.5's,, so I have confidence i'm not going to damage the shock by bottoming it's travel; therefore, I don't run limit straps in the front. The shocks are also mounted far outboard and nothing comes close to binding on the front end.
If you are going to use limit straps, remember, for every 12' of strap, they will stretch 1", and you can customize your length by fabing up taller or shorter tabs

 

The Mopar Stage 3 lift comes with limiting straps. Here a link to a video on the install. They show where they mount starting at 3:25 into the video. https://m.youtube.com/watch?v=KyJzW38fyjo&desktop_uri=%2Fwatch%3Fv%3DKyJzW38fyjo

 

Dang the video did not work.

 

Here's the link, first one didn't work for whatever reason. https://m.youtube.com/watch?v=KyJzW38fyjo

 

I found some nice looking mounts from poly performance that allow adjustment, which seams would be quite beneficial. They also have decently priced straps in just about any length needed...

POLY PERFORMANCE OFF-ROAD PARTS :: Limit Straps

 

I run 5 limit straps. I get them from Filthymotorsports.com but you can get them from other places like poly.
The only kit I have seen that includes them is the stage 3 Mopar lift.
They should be included in any lift really to protect the shocks, driveshafts, and prevent coil unloading.
I use the poly clevis as well, makes it nice to adjust.
