2019+ TH's and ADII have a slightly different front suspension setup
TeraFlex 2” Lift
I haven’t seen a thread yet showing this, but there is a new contender for a 2” lift. I’m curious how this one will perform in terms of longevity. The pricing does seem to be competitive as well. The installation video is below. There is a link to the product in the video description.

Good damn question...There was the subtle cosmetic change in the front facia and the tailgate in 2019, but I'm pretty sure that the suspension geometry and components, and the whole rest of the car are exactly the same from 2014-2022...😎What specificaly are the 'new' Trailhawks? What is the model year cutoff to be considered 'new'?
What's different???😎2019+ TH's and ADII have a slightly different front suspension setup
Does the Teraflex kit add 2" to the Trailhawk, or just the non-Trailhawk? Or I guess IOW, how much lift will the kit give a (pre-2019) TH?

2019+ is "new"
Boy Howdy, now there's a set of good instructions. Obviously, I'd like a little more detail, but these get the job done.
All "lifts" push the operation zone to the extension limit of shocks and struts, which of course limits the articulation. The articulation is also limited by the LCA geometry and the operational range of the CV axles and ball joints. The worst being the passenger rear axle since it is the shortest.
I see all "lift" kits are incorporating a strut collar. Lessons learned from strut failures of "over" lifted suspensions.

I couldn't tell you exactly what's different, (and my mind is a little fuzzy right now), but I do know for a fact there is something slightly different. something with the control arms I thinkWhat's different???😎
This was a response I got from Hazzard Sky on one of my previous posts:What's different???😎
2019+ sometimes dont see quite 2" mostly due to spring rate, and the different lca design compared to the older gen. Weight plays a big role as well. You can see almost a half inch drop in some vehicle just by filling the gas tank. The 2019+ in general have weird tolerances, where the exact same kit installed on 5 different jeeps will get 5 different measurements.
Glad I'm not the only one who found out about the A arms contacting the subframe. I mentioned getting the full 2" being impossible in my install post 2 years ago (Putting on a lift/leveling kit is way more painful than...) That tells me I didn't do it wrong and that the newer jeeps are different. I was never able to get them all the way down to the "2 inch" level measuring spacer that was provided with the hazard sky lift. I don't think this difference gets talked about enough here on the forums.I contacted them today and here is the response I received from tech support
1: The rear spacers are made from a composite glass filled nylon material.
2: We found that on the newer Trailhawks that the newer model years actually limited the down travel on the A arms with them making contact the bottom of the engine cradle/subframe, making it nearly impossible to get the front strut spacers into place. Our kit does in fact fit the new Trailhawks, but the installation is tricky and the performance with the limited front down travel issue, so it wasn't ideal enough to recommend it.
3: We found the rear wheel centering wasn't enough to interfere with proper suspension geometry in our testing, so we left it as is to retain as many OEM parts as possible.
Though I currently run Dobinson plus lift on my 2017, this seems like a decent set up and the price is so attractive vs the alternatives.
Now we just need a Guinea Pig to do an install
I had the same issue installing the Rough Country 2” kit on my 2019 TH. RC officially says it’s not compatible. I was able to get the collars on, but I was at the extreme limits of the Dow travel to get the collars in place.
Are there any reviews on the forum of the Teraflex in a pre-2019 Trailhawk (didn't find any with search.) Wondering if any negative effects on suspension, such as articulation limitations or lack of sufficient rebound travel.
I don't think anyone on here has tried it yet. It's only been available for a few weeks...😎Are there any reviews on the forum of the Teraflex in a pre-2019 Trailhawk (didn't find any with search.)

Ah, wasn't aware it was that new, thanks.I don't think anyone on here has tried it yet. It's only been available for a few weeks...😎
considering the kit is designed exactly the same way all the other kits for the KL are, I can’t imagine it would have any issues not already discussed in regards to the other kits. I mean, it’s spacers in the rear springs, and spacer collars on the front strut between the knuckle and the welded stop tab.Are there any reviews on the forum of the Teraflex in a pre-2019 Trailhawk (didn't find any with search.)

Since there has been some discussion on fitment with the newer trailhawks, I’d like to see if someone can help me with a question I have. To anyone who has either the MFC or Hazard sky 2” kit, can you measure the total height of your front lift collars? Not how much it lifted the Jeep, but the actual collars themselves. I’m thinking that they must be slightly shorter than the Rough Country and Teraflex collars, since it’s troublesome to fit the RC and TF, but not the other two on the 2019+ TH. My RC ones are approximately 1 7/8” tall.
One notable difference between this kit and others would be the rear shock brackets.considering the kit is designed exactly the same way all the other kits for the KL are, I can’t imagine it would have any issues not already discussed in regards to the other kits.

Yep, that is different...😎
That’s very true. I was obviously thinking more in terms of the way the kit adds lift. The Teraflex definitely has one up on the competition with the Shock extension.One notable difference between this kit and others would be the rear shock brackets.
Im not sure how tall my HS 2 inch lift collars are, but the lift did not lift the Jeep a full 2 inches. HS told me the kit itself is 2 inches (so that may be your answer there), but since the suspension on the 2019+ is ever so different than before, you may see different results. I ended up gaining about 1.75 inches of ground clearanceSince there has been some discussion on fitment with the newer trailhawks, I’d like to see if someone can help me with a question I have.

I just ordered this kit and plan on putting some 245 70 17's on my 2019 Trailhawk. I will post pics following the install.
