lowering my TJ - yes lowering

I am sure there are some folks that read that title came here to tell me I am an idiot. But here is the issue, the person I bought it from put a 6-inch lift on it. He also said he bought springs for a different model because they give another inch lift, so maybe 7 inches? It is a 99 with 33-inch tires and the bottom of the door is 33.5 inches off the ground.

Iíd like to go to 35s. It has the flat steel fenders up front. I think 35s should fit with 4 inches of lift. Does anyone know for sure?

Can I simply cut the springs by 2 inches? If I order springs for a 4 inch lift can I simply put them in, or will I need to make other changes?

I am a competent mechanic but all my time has been spent on sports cars. I just donít know anything about 4X4 suspensions.

Where are the pictures??? You got to share!

Do you know what kind of lift is on there? Do you know if the springs are progressive rate or dual rate?

Depending on the control arms, you should be able to dial the pinion back in for a 4 inch lift.

I have 3.5 in springs that gave me just over 4 in of lift, I have flat fenders and have decent flex/range with my 35s.

It is currently 117 degrees (Phoenix) according to my thermometer so I just took some pics in my garage.

The control arms appear to be adjustable but I donít know how far I will need to go. Doesnít seem like it should be that much. But it also seems like it may affect steering components, maybe shock length, is there anything that limits how far down a wheel can fall? I donít see anything but online I see rigs that look like they have a limiting strap. I am wondering if I am missing something. I donít want a spring to fall out because other components are set to move too far. However, I am 4 wheeling with my 5 year old so we arenít doing anything crazy. I am also not an experienced off road driver so Iíll be taking it easy for a bit.

I am 46 and I have a lot of miles on me. Iíd really like to get the seat height down an inch or more.

Currie doesn't make a 6" spring for TJs. So if it is Currie, and it does look like it, it is only a 4" spring. You can measure between the spring perches to find out for sure. Stock is 12" in front and 8" in the rear.

It's pretty obvious in the last picture that there are 2" spacers installed atop the front springs. Chances are good the rear also has spacers then, so all that should be needed to drop the Jeep down where it should be is to remove these spacers.

Front looks more like the spring isolator with a similar width spacer.

Great info. Thank you all.

I measured and yest the spring is 16 inches (so a 4 inch lift per Sh00ttok). The thing at the top feels like a hard rubber or maybe a not so hard plastic. What is a spring isolator?

The rear doesn't appear to have this spacer. However the jeep sits level - see pics below.

Could this be a leveling kit? Does the TJ have a bit of a rake when it is stock? I know this was a thing people did to Tacoma's when I had one of those.

Thank you again for the help!

It is likely a 3/4" spacer. TJs did have a slight take to them and it may have needed a spacer to get it level. Oddly enough, mine needed a rear spacer to keep it from butt dragging so each Jeep is a little different.

Since it measures 16", it is likely that the front springs sagged a little and they added the spacer to compensate. Either way, it looks like a 4" lift

To clarify, it is 18 inches from top to bottom but the spring only makes up 16 inches of that. There appears to be two pieces of the spacer on the top. one part is thicker than the other, so maybe it is 1.5 in and .75? the rear spring measures about 13 inches, but it isn't straight up and down int kinda bows back a bit. It might be 14 total legnth. Is it possible that someone used a 4 inch lift in the front with spacers and a 6 inch from a different manufacturer in the back?

I parked it next to a YJ that the owner tells me has a 6 inch lift. It is slightly tall than the YJbut we measured the tires and mine are about a half inch taller when on the ground (you know with the bottom squished).

Did the YJ and TJ sit about the same height stock or did the TJ start 2 higher?

My TJ and YJ have 6” of lift and the same tires. TJ is about an inch taller.

What’s the deal with the frame side control arm brackets? Are they just bolted to the frame? If so, I’d look into welding on a real set of control arm brackets.

Can you get us a close up of the top of the front coils? We can then clarify if its a spacer with the factory isolator or if its a pair of stacked spacers.

You have a Rough Country long arm kit. The coils could have settled a little.
