Coil conversion on a YJ

[spitfire]

How many people have done the coil conversion and how do they like it. Pros and cons of the kit. And hopefully some pics and a write up would be nice.

I suggest you forget their little kit and do this...

HP XJ D30 front

Ford 8.8" rear

Front has brackets but you need to add for rear brackets (really pretty easy to build yourself).

Get a RE longarm kit and make the transfercase skid work with your chassis if it won't already. Then triangulate the uppers so no need for track bar.

All told you will probably save close to a grand and have a better drivetrain to boot.

First of all Jeep_TJ_Freak doesnt make any sense. There is much more to it than what he posted and the TJ skid does not work on a YJ. Plus all the additional frabrication. The whole point of a kit is so you dont have to do all the extra stuff and thats what he is asking about.

Most coil conversions I have seen cost anywhere from 2000 - 3000. These include the Pro Comp, Black Diamond, and Rockkrawler kits. When I was researching them I was quoted for installation at about 1000 for all the welding and set up. Thats alomst 4000. I have seen some 4 cyl TJ's for that much. Do you see where I am going with this?

look at all the kits out there for the YJ...

the black diamond kit you have to weld on everything ...
procomp have to drill too many holes in frame,
rockkrawler.god only knows what kind of fabrication is necesary to make that kit work

Jeep_TJ_Freak's point is right on the money it wont take anymore to make what he suggested work, then it will to make a "Kit" work

Jeep_TJ_Freak's point is right on the money it wont take anymore to make what he suggested work, then it will to make a "Kit" work unless its with coilovers, the springs will be really short like the pro comp kit. The TJ frame is a lot more curvy to give the coils room.

Im with Jeep_TJ on this one. Make it yourself. It aint as hard as it seems.

May not be hard but some of us really don't have any fabrication skills nor the time to experiment. I can't have my jeep tore apart for weeks on end getting the suspension correct.

Nope and it kinda looks as though some others see wher each of us are coming from.

It is a damn good thing you aren't spitfire then.

If you can't get that done in a weekend then you can't install one of those coil conversion kits either.

Besides it was just an idea, I think all those conversion kits are crap. It doesn't matter how much it costs.

[Eryl Flynn]

Never said I would be doing the install on a coil conversion. But then again I know I can't weld so that rules out the black diamond and Rock Krawler one.

Besides if it as so easy why are so many shops that I ask if they can and what they would charge telling me they won't even try, too much work involved?

Hell I don't even know what parts I would need to have on hand to start the whole thing. Yea, springs, mounting brackets, but past that, the arms, how to mount them, where what type of joints to use. All past me at this time.

if you dont have fab skills should you be doing a coil conversion?

none of the kits out there appear to be 100% bolt on. The Black Diamond definitly is not and it is supposed to be the best 'kit' out there.

making it XJ like, with coils front, SOA rear would be awesome.

[tperretta]

Find DUKSRULE on here and pm him.

He has coil conversion. I talked to him about it. He said it was completely bolt on and he did it in a day and a half and wouldve been done sooner, but he misplaced a part.

He told me it's a great mod and he would recommend it to anyone. just talk to him.

I'd been toying with that idea. Find an XJ HP D30 and SOA my 8.8 rear. That would be sweet. But I'm currently unemployed, so its just a pipe dream. :(

fawk coils- just put the leafs spring over :)

[ksdaoski]

it appeared you were working for Kilby Ent?

have to fab upper mounts, track bar, couple links, and good to go! I dont think the front frame would as troublesome as the rear would be.

I was working for Kilby, up till yesterday when I was laid off. Fault of my own Im sure. Its ok something will work out, and I still know that kilby makes some of the best products out there. As far as fabbing in the front VS the rear, yeah, it would be a lot easier to setup I would think.

Jeep_TJ_Freak - after reading my post I realize I may have come of as a little harsh. I see where you are coming from. I have often thought about it and think that fabbing your own suspension would be very difficult. Such as getting all the lengths correct for the arms, positions all teh brackets in the perfect place, etc etc. I would be really worried about screwing it up. Therefore I would go with a "kit" that asomeone has figured all this out already, even if I pay for it.

[spitfire]

Thank you everybody for you info. I guess I won't be doing a coil conversion. If I have the time and money to do something I think I would go SOA, if I was to do anything.

I'm in the process of round-springn' the rear of my YJ. Custom building everything.

Ether I'm getting slow in my old age, or you guys are lighting-fast.

I've got over 30 hours in it so far and I still have the thing all apart. I've played with two different UCA lengths and mounting points, two different LCA lengths and several different mounting points.

It is not as easy as one would think, and this is not my first rodeo. I have done several custom one-off coil/link suspensions, and everyone is different. Adapting to the different chassis configurations is a challenge.

If you do not have the tools, and ability to custom build all the brackets, arms, tabs, and figure out the CORRECT location for everything, I suggest that you buy a "kit", even if it requires welding. That is the easy part, IMO.

hmm... I see we have some opinions in here... personally, the biggest complaint I've ever heard about coil overs is the price... werd is they wheel just fine and if they're put on right, both the onroad and offroad manners are better than leafs, or so I'm told...


by the way, do any reply's in here actually have one??? doesn't look like it...

I dont have to eat cow dung to know that it isnt worth eating.

I have converted my YJ front only to coilovers, did bend my leafs a few times and they always bent right back again, but figured i would not get away with it for long before they broke and left me strandard, i got to say im very happy with it and so far does everything right. im trying to post a photo, but if it dont come out e mail me and ill send them to you.
I used QA1 shocks and coilover kits, with Hal 2.5"x14x250lbs springs ended up putting in a helper spring to stop the shock unloading at full droop, but have sinced ordered a set of Ibach 16" x 200lbs springs and when they turn up i should be able to do away with the helpers. it took a couple of weeks to think about what i wanted, a couple days to fab all the brackets, another day to install and as it was structual i wanted someone who new what they were doing to do the welding for me and waited a couple of days for a friend to come by and weld it for me, the shock towers are in the oridinal place but are fabricated from 3x2 box, the panhard chassis mount was moved back a couple of inchs in order to keep the bar striaght and clear the steering rod. At this stage i am not unhappy with the leafs in the rear and have no plans to change them out.
