Lift height coming in much taller than advertised

I don’t disagree that looks tall for a 2.5” lift on 37s. Typically that is a much more proportional set up. I’d talk to your shop, it’s possible they ordered an incorrect spring size. I know these lifts do run a little tall, but this seems like a lot. Looks equivalent to my 3.5” Clayton lift. FWIW I don’t think it looks terrible, a larger tire such as a 38 would make it look much more proportional.

Clearly the wrong lift was installed….no way you are 3 inched above advertised on the lift you ordered. Most are lower as advertised, and this is your 11th Jeep, you are an expert, they should make it right.
It has to be the wrong lift considering it's taller than my Teraflex 3.5 kit.
 
It is definitely that tall. I measured in several different spots before the lift and measured again after the lift was installed. I gained about 6 in the front and 5.5 in the rear.
That is just crazy especially considering my Teraflex 3.5 raised mine 3.5". Your shop installed the wrong kit.
 
Wrong springs. Some spring measurements will verify.

No, I ordered the kit directly from TeraFlex. I have verified the part numbers that is printed on the springs. TeraFlex says they are correct.

I went over all the part numbers with TeraFlex. We have verified that the correct number that is stamped on the spring is what they sent. I still believe they are the wrong springs but TeraFlex doesn’t know what the right spring would be.

I’m so confused. I have never had a lift do this before. Something is definitely off with their kit. They just don’t know how to fix it.

It is measuring out to be a 4.5 lift. As is it doesn’t look right. It does need bigger tires. There is too much air space.

Thank you very much! Yes it is definitely the wrong kit. But Teraflex says all the parts numbers are correct for the kit that I ordered and should only be raising it 2.5 inches from the factory lift. They don’t know why it ended up so tall.

What does the installer say? Have they added additional spring spacers (or left any in-place) by mistake? Teraflex has a high and standard capacity lifts. Did you get the high capacity one? That would require a very heavy (overland style) Jeep.
 
Just as a note, the AEV 3" High Capacity springs are identical hight wise with the 2024 392 OEM.

The only difference is the massive difference in their wire thickness, probably 2x as thick as the OEM. Perhaps your 392 is too light for the springs. Have you added (or intend to add) any armor, shelving, etc in the future? You might want to communicate this to Teraflex to help your sizing.
After the suspension, tires and wheels I only plan to add a winch plate and winch.
 
These are the measurements of my 2.5 Aev lift before and after. About 2 inches gain front and back. Looks good with the 37s. Rides and drives great. I did end up keeping my longer Mopar Lca’s for a tad more caster. No driveline vibes

Thank you for sharing this info and for all the pics and dimensions. That is exactly what I was looking for. I may have to just purchase the AEV springs and be done. Thanks again

That might be a problem. Perhaps spacers would've been a better solution for you. Any lift will offshoot on a light vehicle.
 
Nittos are bigger than the same size KO2s. Please check you exact load-rating but it looks like the Nitto (at 36.7") is 2.25" taller than your 35" KO2. (34.5"). Out of your 6" height you gained 3.75" vs the 2.5" lift you purchased. So overall you gained 1.25" more than you expected. It sucks in your position but 1" extra is common- and you've got an added 1/4". I am surprised that TF doesn't have a disclaimer on lift because they sure as heck used to. Most people think more is better which is why they may not be overly helpful. Their customer service is usually good; maybe try again?
And per above- your driveshaft isn't going to "go" anytime soon. But I would disagree with others- you've gained a lot of height so you do need to keep an eye on it for sure. (That's the thing people need to remember- its not just the lift height but the added height of the tire.)
And PS- as a female Jeep I'd assume that extra height is a pain in the ass. Which others may not get. My JK has a 4" lift on 35s. I never went to 37s because I didn't want the extra height. Gets old as a DD.
From all the calculations that we have done with TeraFlex it looks like we are about 3 inches taller than than we should be. More is definitely not better. I was wanting a particular stance and look and this was not it. I was also not wanting to have to replace my driveshaft and other parts due to the extra height. Teraflex is trying to work with me but they don’t know what has happened. They say all the part numbers are correct and it should have only raised it 2.5 inches. Yes, the extra height is a pain in the ass. I am only 5’3 so it is not easy getting into this Jeep. My JK has a 4.5 inch lift and 37 but I have built it for the height. It isn’t a daily or it wouldn’t be that tall. 😂

I would like to find a shorter spring. I have seen many 392’s with a minimal lift that look amazing and they aren’t that equipped. Spacer may be an option if I can’t figure it out.

He says it is very tall and TeraFlex sent the wrong springs. They are the springs that they recommend for a 392.
 
Are the “correct numbers “ just a paper tag on the springs ?

I would take a caliper and measure the coil diameter and then count the number of coils from bottom to top and send that info. Wrong springs.

I am saying it's their 3.5" kit. It looks like the same height as mine. I actually love how yours looks but I understand it's not what you wanted.

Can you list the exact kit you purchased and take some measurements?

It may be time to discuss it with a different shop too. Give Rebel Offroad or Redemption Offroad a call and see if they can help you.

This is my Teraflex 3.5 RT3 kit that came out 3..5" plus another inch on the tires.

With that much lift, the shocks might already be fully extended if the wrong springs. Diameter of coils and coil count would be very helpful to solve this riddle.

I hope you get this resolved soon.
