Forgot it was something like 13 inches tall ? Lot of lift for 35s.



Perhaps he has bigger tires in mind.

God I hope so. That set-up is way less than desirable for his kind of wheelin. Glad he at least has a winch to lower it when hill climbing LOL

The front isnt doing near enough causing that rear to overcompensate something crazy. Yeah that flex pic doesnt look like much but that 4-link isnt doing much to plant its feet in all 4 corners...

Those are at least 36s. In Irocks that means theyre almost 37s.

What axles he running? You know?

i think the links in the rear do very little in this guys situation.

You can see the front tires alomost parallel and the rear is doing al the work. If it was set up better that Jeep wouldnt be so leaned to the right. On that obstacle it doesnt look like the front could do much but the rear just unloaded that left rear which threw the frontright down a lot.

Statements like this are very frustrating to me!! You don't know this guy from Adam, and yet you feel that it's OK to basically bash him on a public forum....UNCOOL to the highest degree. As a matter of fact, he isn't even a member of our board yet, and therefore cannot defend himself...UNCOOL again!! Read the ENTIRE thread before you publicly bash someone. The thread states that he DOES indeed have limiting straps, but failed to put them on for this trip!! You need to rethink the way you criticize someone's work and/or their intelligence...PERIOD!! This not the first thread TODAY that I have viewed that you did this very thing!! I'm not saying that you cannot disagree with someone's decisions, and/or designs. There is a little thing I like to call class, and that is the ability to criticize someone's stuff, but not look like a jerk doing it, and I guess I'll leave it at that!!

Show me an XJ that has a "balanced" suspension. LOL!! I know they are out there, but it is hard to accomplish due to the leafs in the rear and coils being up front. Especially when lifted, since lifted leafs are usually a higher rate than stock. Personally, I like this guys set up, with the addition of some limiting straps, and a different shock configuration, it would be a killer rig to have, IMHO.

Mainly because I don't spout out information without giving a solid reason or backup. I try to teach folks, not just tell them why something "is" I never said he doesn't know anything .... I said he is posting a lot of bad information.


To simply criticize is one thing. To offer input (i.e constructive criticism) is another. I guess we'll all have to come back to him when we learn the usefullness of a limiting strap ?



I've been doing this for almost as long as he's been alive (if I'm remembering his age correctly). I think I'm qualified to show people a few things every now & again.


Obviously, I did not recall the tire size correctly. That thread (hackett gulch) said 15-16 inches & 36's. Definitely a large amount of lift for the tire size .....

Even with 4 coils ... it's difficult to get a perfect balance. Lots of other variables besides spring rate.


I like the idea of the front working a bit more than the back .... keeps it level more cheaply than all sorts of sways, anti rocks, etc.


So tell me again why I went with coils ?

I feel the front working is a good thing too. It feels more "planted" during techy climbs. I had a lifted ZJ a few years back, and even with the quadra coil set up, they work the front a bit more than the back. I'm assuming that it is the weight of the drive train being focused more towards the front, but am unsure, it's just something that I noticed.

Thanks COSXJFAN. Like I said, it was definitely his bad (maybe mine too) to not have those L straps. I will tell you guys this though, that xj is well built. He did alot of research on the build, and I believe it's a very safe rig to wheel in. This pic was about the closest I have ever seen it come near to flopping and it was still not close. I have never even seen him lift a tire. That D60 on 36x13s is HEAVY. He may have too much lift, but that's his prerogative.

If you look closely, as much as the pic can tell. The front pass tire slid into a deep rut. With leafs, you were sure to flop. I did not try this line because that rut would've swallowed my lil xj. Like I said, longer bumpstops are in order this wknd, so the chance of a un-coiled spring to fly out will be scratched (as if there was a chance of that happening). I have personally helped hold the spring while he moved the rig to drop back on the bumpstop. Never felt any risk of being hurt.

I agree 100% Seth, I personally am not a fan of too much lift. His fenders were not even close to hitting the tire on this twist. He's planning on going to 39s or 40s though, so maybe that will change then lol. His axles are full width too, so that helps with stability even w/that amount of lift. He built it using various springs and adjustable spacers so I really don't know the amount of lift, but the 15" is just my guess.

Yeah, when I saw that earlier, I was thinking that it was a touch on the high side. It doesn't look like 15" to me, but I have been wrong before, and likely will be again!! LOL!!
