So I'm sitting in class today thinking about how I can put coilovers on my YJ when the thought came to me....what is stopping someone with a YJ from putting a Tera longarm kit on a YJ? It comes with a new skidplate with the UCA mounts right? And basically every bracket that comes with the stock TJ has to be torched off except the axle mounts right? Seems like it could be done with minimal trouble. I'd like to see if it could be done with coilovers instead of regular coils. Is it possible?

Im not positive but I think the t-case skid plates are different as far as frame width... Not positve though, im a YJ guy.

Really I just got bored and was thinking... I was planning on making my own arms and such but I was simply wondering if it was possible. I'm probably going to do a design similar to the Tera kit or some other big lift kit for TJs since all the suspension geometry is figured out and all that stuff is pretty complicated and if I screw it up its going to be costly. So what design should I look at for ideas?

Nope. Tera's kit utilizes the stock TJ UCA's including all the bracketry at the frame and the axles, something you don't have with your YJ. Additionally, you don't have the necessary bracketry on your axles to mount the control arms, granted you could buy all the bracketry from RE and weld it on.

If you want a good model for a YJ coilover suspension, look to Warn's Black Diamond setup ... whether or not you can find one anymore ... I don't know.

On a side note, if Tera thinks they got a good thing going with a suspension that utilizes long lowers and short uppers, they need to have one of their "acme joints" crammed right up their arse. Kudos to guys like Schlingdawg that have the sense to take a half arse'd idea and make it work by adding their own long uppers.

Nope... I'm looking for lift to clear 39.5" Boggers <IMG SRC="smilies/biggrin.gif" border="0">

Use the Warn kit as a model. Obviously, as it is, it ain't gonna' fit 39.5's ... no aftermarket kit will. You are definitely into the range of a custom setup.

The geometry of the Warn kit works, so use that as a base to start with. In order to make that model work with the clearance you need, you are going to have to mount the axle brackets "higher" on the axles than normal. By that I mean; don't mount the lower control arm pivots under the axle, a la TJ. Instead, mount the LCA pivots either in the same plane as the axle tubes or even on top of the axle tubes. You will then have to build "risers" off which to mount the UCA's. The reason I said 3 link is because the axle's center section is a natural "riser" from which to mount the third link.

By keeping the axle brackets high, you keep the control arm angles relatively flat while still yielding room for your meats.

no kidding <IMG SRC="smilies/rolleyes.gif" border="0"> .

The only problem I see with your ideas are that with risers placed off the axle for mounts there is a bunch of stress added there. I planned on doing a 3 link anyways but there is no way I can have enough lift for the tires with the amount of flex it will have unless the arms are angled (i.e. not flat)

I've been thinking about how to put coilovers on my YJ too. I am going to basically model warn's kit, but make a three piece skidplate to allow tranny access. I only want to match my current SOA for height, though.

I believe that the warn kit could take substantially more lift without aversely affecting ride/handling. Look at Skyjacker's kit... they have 8" lift and the control arms aren't nearly as long a warns. However, you will run into some serious driveline issues unless you use hp axles. I would try for about 7-8" suspension lift, 1-2" body lift and a sawzall.

I'm going to sawzall the front and put avalanche comp corners on the rear so I figure I will need around 8"-10" lift over stock. I'm going to make the arms as long as feasable to get them as flat as possible. Definitely going with a triangulated 3 link in the rear just not sure what I want to do about the front yet. What does everyone recommend? Keep in mind its a daily driver rig so it has to be stable on the highway.

Thats pretty much what I'm going for in the way of clearance and overall width. I just need to figure out the geometry of the links and such.

btw: I've seen those pics before <IMG SRC="smilies/eek.gif" border="0">

look into the RE long arm kit, similar to the warn in design, but not designed for the coil overs. but I have seen a few tj's running 39's with this kit, and all you'd need is the four coilovers and some mounts.

there is a company that bought the design and tooling from warn so they could continue making the warn stuff, so it is out there.

Ok so the upper arms are short. I will give you that one. But Just dont use the same length as they recomend. I made mine longer and its fine. Yes I have a lower Teraflex long arm kit.

But my big question is why do you want coils?
Ok maybee in the front but not in the back.
Seems to me that Brad Kilby changed his TJ to a coil front and leaf rear. He loves it.
check out his website.
www.onboardair.com and see the pics/story.
If you ever bought anything from brad you would understand that his worksmanship is top notch! and if he likes the rear leaf idea. Maybee you should think about only coiling the front. like an XJ.

The main reasons I am going to coils is to get rid of wheelhop, its more forgiving, more flex, and I want to do something that isn't just bolt on stuff. anyone can take do a SOA conversion and add lift springs but coils take work <IMG SRC="smilies/biggrin.gif" border="0">

I agree. But according to Borton coils front and rear suck and since hes a rock god and I'm a lowly wheeler he must be right.

Ponder this........Rod Hall made an S-10 with a front suspension that hung from the front of the frame.....Why not take MORE SRS front shackles and hang a triangulated arm from the front and a track bar like the rest of the coiled ones and use your coilovers for as much lift as you want.....just a thought....come on suspension gurus.....Rod Hall cant be wrong??

I've never seen that s-10 but my only reservation about that is that to get the links long enough for any decent amount of lift there would have to be alot of frame up front to mount the arms to. That kinda defeats the purpose of going coilovers and linked suspension if you look at it from the point of approach angle.
