Ok boys and girls, this is it, the first Thread Of The Month for the Jeepspeed section, and I'm going to start with what I think is one of the most important topics you can possibly cover for the XJ... UNIBODY STIFFENING. We all know too well how destroyed our bodies become over time, let's see how you all remedy that!

well i havent had to deal with this plague...YET its only a matter of time before you have to repair the body strengthened or not. i have heard of people laying a plate over a tear in the body but the strength has already been affected. but i do not have any picture proof of plate work to fix tears
heres my front thread, very basic, run of the mill front frame stiffening http://naxja.org/forum/showthread.php?t=1016379
if i was going to do my frame stiffeners again, today. i'd go with ruffstuff again, but i would fab up a way to tie in the stock seat bolts into the frame stiffeners, the outside studs pretty much get in the way, so tieing em in would be allmost effortless.

here is the centers:
so basically i was getting tired of all the creaking that my jeep was doing even when going around corners, soooooo i went ahead and shelled out the clams (not that many for what you get), and got stiffeners from BRIANHO13 on www.hdoffroadengineering.com (http://www.hdoffroadengineering.com/). here is what showed up:
http://i87.photobucket.com/albums/k151/dgrigorenko/P4080768.jpg
at first glance i was pretty happy with what i got, although i was surprised at how light they were, but i suppose that could be because of the bazillion plug weld holes. these are made of 10ga sheet metal, which is slightly thicker than 1/8"(11GA), and slightly thinner than 3/16, which to me was a pretty good compromise of weight and strength.
one of the first things i had to do was modify where they had the crossmember bolt slots due to me having the TNT long arm kit:
http://i87.photobucket.com/albums/k151/dgrigorenko/P4080770.jpg
http://i87.photobucket.com/albums/k151/dgrigorenko/P4080771.jpg
next i had to start taking apart some of the crossmember mounting points, and cut off the crush sleeves to fit. i also decided not to completely drop the crossmember, instead i would just lower it enough to slide the stiffeners in
http://i87.photobucket.com/albums/k151/dgrigorenko/P4080772.jpg
next came the really dirty part: cleaning off the rubber undercoating it went fairly quickly with an angle grinder and wire brush, but what id didnt take off was the paint, which i ended up being happy about. I decided that in order to keep some sort of protection from the elements i would only take off paint where i needed to, and not off the whole rail. i mocked up the stiffeners and with a sharpie i marked where all the plug welds were going to go, and only ground off where i needed to.
http://i87.photobucket.com/albums/k151/dgrigorenko/P4080774.jpg
http://i87.photobucket.com/albums/k151/dgrigorenko/P4080776.jpg
I also decided to use some of Krylon's "weld through" primer to prime the backside of my stiffeners. I used this not because i was planning on welding through it, but because it doesnt burn... this way there is still some weather protection, but still no paint where the welding is going to go...
http://i87.photobucket.com/albums/k151/dgrigorenko/P4080777.jpg
http://i87.photobucket.com/albums/k151/dgrigorenko/P4080778.jpg
Next came the mounting up... i only had 2 large C-clamps and a hydraulic floor jack, so i started at the front, would clamp and jack, spot weld, and then move back. this method seemed to work pretty well with getting things tight.
http://i87.photobucket.com/albums/k151/dgrigorenko/P4080779.jpg
then there was the welding.... lots and lots of welding... and moving from side to side and front to back to make sure nothing got too hot.
http://i87.photobucket.com/albums/k151/dgrigorenko/P4090780.jpg
let me tell you, there are a lot of plug welds on this thing....... IMO its kinda excessive, and something like the ones ruffstuff has is probably more than sufficient.
i then ground things down to smooth them out
http://i87.photobucket.com/albums/k151/dgrigorenko/P4090781.jpg
Then i used some primer that i have heard good things about, this is the first time i have used it, so i guess i will find out how good it really is. Rustoleum self etching primer... first i cleaned it up with some acetone to make sure everything was squeaky clean, then coated it up. it had great coverage in my opinion so i am happy with it at this point.
http://i87.photobucket.com/albums/k151/dgrigorenko/P4100793.jpg
http://i87.photobucket.com/albums/k151/dgrigorenko/P4100794.jpg
I dont have any pics of it with final black paint on it, but i think we get the idea.
Overall thoughts on this install: not that hard, just some good ol grunt work. it took me about 3 evenings to complete, so thats not too bad either. I took it for a test drive and was VERY happy with the results. no more creaking when i drive over a man hole... i even took it up on a rock to flex it, and it barely made noise... this is a vast improvement from what it was. even just the feel on road driving is improved, it just feels much more solid than it was. now a couple of things to consider is that i do have the TNT belly skid tying these together which no doubt helps. I also have a very solid rear bumper, front bumper and the track bar brace, so there are a lot of things tying frame rails to frame rails. i think my next item on the list is plating from the back of these stiffeners to the bumper, and same on the front. i have not decided if i want to get the TMR ones or just make my own...
Final Note: i would like to thank NAXJA as a whole, and all the writups that i have read to get my rig to where it is now, and doing it right... i am glad that i can give a little bit back.

thats not fixing, thats patching.
even with mild wheeling i feel my jeep twisting up when i go out. thats why i plan to add stiffeners BEFORE i even get started up with the go fast stuff. my unibody is strait and id like to keep it that way. i think as far as structural integrity goes, stiffeners are a essential for going fast... i say good first thread jim. ill be keeping up with this one to see if i can get any good idea. :)

I did my stiffening in 3 stages;
1. TNT / Treks 3/16" plate stiffeners
2. TMR 1/8" front frame plates
3. T&J / Currie Tubular frame stiffeners
I think the combination of the 3 is what made such a difference. I noticed a different right away when I did the TNT stiffeners, my dash wouldn't crack anymore going over bumps, or through driveways. But about a week later the creeks and cracks came back, this is when I decided to go all the way.

Note that this isn't all that we did. We plated the frame for basically the entire length of the car. The tube stiffener ties the front and rear suspension points together AND also ties bottom of all the cage hoops.
From there, we have a lot of sections in the car where we tied the cage into the body. You can see them along the front fender and along the a-pillar. We have plates like that all over the car.

2. TMR 1/8" front frame plates
3. T&J / Currie Tubular frame stiffeners
I will tell you guys right now... Jim is absolutely right on this subject, and this is the way to go!! Makes a huge difference in performance.
I will also tell you, I have seen many people say " i do not need them yet "..... I would HIGHLY HIGHLY suggest you do this to your XJs as early in the build as you can, it will save you later from having to repair, and replace things.....
Do it first, and save the headaches later!

I think this is probably the most important thing you could can do. While the frame plating in key points is critcal, i feel tying the cage to the body everywhere you can will give you the most rigidity possible.

So to what extent can you do those three things without them being tied to a cage? Do they interfere with any other parts you might be putting on so you need to plan for that?

I completely agree here. I'll have plenty of plating once my cage gets finished as well.

If you're talking about mine, it's hindered me a bit but nothing that can't be overcome. It prevents most crossmember's from most long arm kits from just being "bolt on". Bit honestly I'm past the point of bolt on items, and will be building my own arm mounts. Also, I'm still fighting with ideas on where to tie in my cage, there's a good chance my T&J stiffeners will be coming off temporarily.

I found this thread because today it was evident that I need to really do something about the twisting. I bet we have all been on the trail and had to open the back hatch and were unable to get it latched again till we got to flatter ground, or just smashed it closed. Today I parked one tire up on a curb stop at the store and when I went to shut the groceries in the back the hatch hit my rear bumper (aftermarket bumper). I really thought to myself that NO, this has to be taken care of NOW, especially since I wheel it quite often. I will be searching and posting up what I will do in the future for my strengthening strategy. This thread has been very helpful thus far.

Note that all this frame stiffening and plating is great, but our old un-plated car never cracked or broke a rail. IMHO, cage and overall structure is more important than these frame plates. The biggest problem area is the spring bucket. That was a constant battle of realigning the bump cans because the pockets kept deforming. And if you are already cracking, there is very little you can do to save it.
No, I'm not pulling on it - that is the extent of the deformation.

Look at the back side of the bucket -

Cracks, failing spot welds, entire fenderwell structure was failing.

my buddy told me on saturday that following my XJ down the freeway was like watching a stripper, the ass was shaking the whole time :roflmao:
all the spotwelds around my hatch are pulled out, and i've got cracks all over the place in the back end. i'll be junking this shell and plating and caging the new one before i start beating on it this time, as was mentioned earlier once they start you will just be chasing them and making repairs constantly.
I'd like to add to this topic plating and re-enforcing the leaf spring pockets, mostly in the front but in the rear as well. this area takes a lot of abuse, and is only supported by the floor pan and the thin cross brace that runs under the front of the rear seat. Something like Poly Performance's leaf spring mounts (http://www.polyperformance.com/shop/Poly-Performance-Jeep-XJ-Rear-Spring-Hanger-Bracket-p-20685.html), or what the Fat City boys did on Stobaugh's build thread (http://naxja.org/forum/showpost.php?p=244877550&postcount=33), would be a good idea.
also, dont XXXX with the area near the rear, where people commonly 'tuck n fold' that was a big mistake for me, IMHO. same with rear fender cutouts.

X2, if you are going to cut out the rear fenders, do a good job welding them back together with something structural. The best thread I've seen on this subject was StumpXJ's - http://www.naxja.org/forum/showthread.php?t=1011630

These along with a rigidco front bumper, the jeep feels solid.
Like Jim said, once mine were welded, it was quiet, but after one wheelin trip, all the noises were back.
Up next are the front and rear stiffeners.
Is there a way to setup those t&j tube stiffeners for people with no lca mounts? (Longarms.)

Mine's not built for JeepSpeed but frame stiffening is a good idea no matter what type of wheeling you do. Similar to a lot of the previous posters here's what I did:
- T&T 3/16" frame stiffeners
- T&T bellypan
- TMR front frame plates
- 2x6 x 3/16" rockers also tied into frame rail
- cage tied into everything
- still have rear frame sections left to do

the cage extends through the roof also:

Each step of the way I noticed improvements in how stiff the unibody was becoming. The most noticeable improvements I'd say were the initial T&T stiffeners and the cage, but it all helps in overall stiffness.

i find that to be grinder wheel abuse, and the smell isnt too pleasant either!
not all underbody's are the same, sometimes it's thin, sometimes its 1/4" thick in spots... try a grinder wheel at the 1/4" spot, you wont get very far!
cook it with a plumbers torch, and it peels right off with a flat knife.
in another thread, someone recommended brake fluid.

I said wire wheel, not grinder wheel. Big difference :lecture:
A grinder wheel would make a truly off-putting smell, you are correct on that.
EDIT: yeah, brake fluid does a pretty good job of removing it. So does brake kleen but I would be wary of doing that since it produces phosgene when you start welding and there is some left in a crevice!

The rears complete, still need to finish the rest

Why doesn't anyone make a brace or big skid plate that ties the framerails together along almost the whole length between the tires? It doesn't have to be one piece, it could be 2 that bolt together. Hell, you could connect to the pinch seams too and have a nice flat underside with some 3Dness for more rigidity.
Similar to this, but filled in for protection. BTW note that this Miata has a more protected cat than almost all of us :D

Because you have a driveshaft (or two) and some other things that hang down below the rails. Look underneath with your suspension extended and see where you could tie the sides together.

And I'd say my cat is pretty well protected. (upper left above the rear diff)

Yeah, it is protected...a little too far back to get hot enough to actually do anything, but at least you won't smash it.

Xj9140, read the post he quoted - I said both work and noted to avoid brake kleen on things being welded
I only wanted to clarify

Suggestion - link this thread (and the other TOTM threads) into the FAQ thread.
