37's with a 4.9 Stroker Kit

Here's what I have:

1999 TJ Sport, 145k miles on it. Pretty clean, rag top, 4.0l, manual trans... rock hard front bumper, POS smittybuilt rear bumper

Sitting on the shop floor:

Poison Spyder Roll Cage (Not the whole cage, just the piece kit)
Poison Spyder Fenders- Whatever the highest clearance ones are...
AEV Hood
2012 JK Dana 44 Axles (Front and Rear complete axles)
Rubicon Express 3.5"

On its way:
505 Performance 4.9 Stroker Kit. Complete with new valves, crank, cam, injectors, etc.... Even a header...
37x13.50r17 Toyo MT's (5)
17x9.5 Raceline BeadLocks (5)
2005 Rubicon 6 speed manual
2005 Rubicon 241 Case
5.13 Gears for the dana 44's
C Gusetts for the front Axle

So. My question is what am I missing.. I'm not talking about the obvious stuff. I know I need new drive shafts.. I'll measure em out and order some from Tom Woods when that time comes. Its been a long time since I did any wrenching on a jeep. A lot has changed. My 75 CJ came with a v8 LOL... This new stuff is a little foreign to me..

So. What little bit of research I've had time to do has told me the trans will mate up to my motor fine.. I have the old style head which according to 505 is the best one. The jeep came with an aluminium radiator.. Is a electric fan a good idea on these. I know it helped out on my 304 in my cj... But not sure about this inline... He also mentioned switching over to MSD electronics.

With the JK axles, so far everyone is saying they are a direct swap?? Is this the case... What about the lift?? Is that a good one or should I sell it for something else. I don't want to go too high. The jk axles are 5" wider and with the Fenders I'm running. I shouldn't have a problem one with the 37's....even with nearly no lift I would think...

Brake lines, abs sensors, speedo? I'm looking for help on the stuff that ends up holding a project down.. I've done things liket his before and a speedo cable that is only in Ca kills a whole week.. I'm just wanting to head that off.

Sorry this is so long. But I wanted to give you guys as much info as I could. I appreciate any and all responses...Well. Most responses anyway....

You have been incredibly misinformed.

The JK axles are anything but a "bolt in" mod for the TJ. The control arm mounts, spring mounts, and shock mounts are all completely different and in different positions. And the biggest difference is the steering. You're going to have to go all custom with the drag link and track bar in order to adapt the JK axles effectively under the TJ.

Unless you have a good working knowledge of steering geometry, this will be over your head. Also, JK front axles only have 6 degrees of separation between the caster and pinion axes. This will cause you problems, as the caster will be at about 0-1* with the pinion inline with the front drive shaft like it should be. You need to be in the 4-5* range. To fix this, you'll have to cut and rotate the C's.

Also, you're wasting your time with the RE suspension. It's absolute junk and will be a chink in the armor of an otherwise seemingly nicely built Jeep (once it's built). I'd recommend changing your plans there. You're no longer on leaf springs and you'll find that coils/links are a completely different game. It's a lot easier to screw things up and RE is pretty good at it. Take a look at Savvy Offroad and Metalcloak for your suspension needs.

The trans will mount up to the motor just fine--TJ motor, TJ trans. I'd personally recommend sticking with a mechanical fan. I'm not a "fan" of electric fans.

Good luck.

Good to know on the axles and RE suspension. I'm gonna have to shoot a few people over the suspension. The axles came at a steal. So I decided it was worth any extra work.

Fixing the camber isn't a big deal. That's what I get for spending a 1/3 of the price of new dana 60's. I'm assuming though with this much change there isn't an issue with the differential and oiling?

So... Who makes the suspension brackets.. I'm assuming that axle swaps are normal in these considering how weak they sound like they are. There has to be more than a few companies who make the brackets... That would be an easy solution to that part of it. Now its just the steering which will probably best be done on the lift... unless you have a solution.

Surely I'm not the only one to do this??

Looks like there are a couple of companies that offer conversion kits for them. IF anybody has a particular company in mind I would appreciate the info. Gonna be doing a little bit of research and will order a kit next week... Motor comes out this weekend.

I really want this done by the end of January. Not a good start at this rate....

Don't worry about "conversions." What brackets will you be using on the frame? You can purchase all the brackets you need through Poly Performance and Artec. Go about this logically and study up on suspension a bit. Once you're there, things should start to click and you will be able to pick and choose the brackets that fit your needs instead of worrying about a pre-packged "conversion kit."

The axles are very good but the front needs some support to hold up well--the C gussets are a good idea. I'd recommend adding outer sleeves before welding any of your new brackets on. These are commonly referred to as "clam shells" and can be found on Poly Performance's site. All of the factory brackets need to come off anyway so the outer sleeves will simply go from the center section to the C's and will become your new axle tube.

Here's a couple threads to help you out with JK axle stuff:

http://www.jeepforum.com/forum/f9/sl...-axle-1227882/

There are some more JK swaps out there. The top two were done by the same guy, who's a good friend of mine. I've had my hand in a few JK axle transplants and will be throwing some under mine in due time.

Thank you for the information.

I'm going to strip them down this weekend and pull the drivetrain out of the tj.

I did a little research last night and came up with the same deal. Brackets on their own.

Am I correct in assuming that the front C's are the only weak point?? How is this E-Locker holding up?? I assume adding sleeves prevents me from running a different locker, like a ARB Air locker... But if the e-locker will hold up then I should be fine for now. This is going to be my daily driver with moderate trail use. Our cabin is located in Cuchara Co and there isn't any real wheeling close. Plus I will be pulling my cj in the shop when this one is done. I've been dying to transplant a diesel into one of these. Since Diesel Tuning is what's paying for all this, it only seems fitting...

The JK Rubi diffs hold up very well. They're not quite up to the strength of ARB's but you shouldn't have any issues. Adding external/outer sleeves has nothing to do with which carrier you run. I'd recommend not bothering with inner sleeves since outers will add more strength and if you have to run an ARB in the future, you'll be able to fit the required 35 spline axle shafts.

Update...

37x13.50 Toyo Muds showed up. Along with my axles, 5.13 gears, front and rear truss, c gussetts, front inner sleeves, Fox 2.0 14" coils for the front, and fox 2.0 12" coils in the rear, warn zeon 10k winch, and some other misc items...

Waiting on the trans, tcase, and stroker kit. Zach from 505 said the kit should ship last week. I haven't had time to call him. Raceline Bead locks should be here this week as well... I'll get some pics up here as soon as I can...

We decided to stretch it, so a new gas tank is on its way as well from Genright, hopefully we can get 8 inch's out of it. Comp Cut fenders from poison spyder are here, and their trail cage as well.

I'm going to have a local shop do the axles and coil over suspension. That's a little bit different than the leaf spring days.... When I was still big into jeeps we were cutting leafs in half and flipping them to make our coil over style suspensions... Boxing the frame and stretching it isn't something I have any experience with either... So I'll let someone else take care of that for me. Plus they really aren't charging me a ton for it either...

I think its worth a little bit... I haven't had time to even go out to the shop this weekend/week. But I'll get the part number off the kit.

I guess there is a classified section on here I'll just list it there..

Let me know how the stroker kit goes. I've known Zach for a long time but I've never done any business with him. I keep considering a stroker and/or a turbo and since he's local and does both I might let him have some of my hard earned money if I hear enough positive reviews.

Will do. It shows up tomorrow.. Its going to be a few weeks to a month before it all goes together.

I've got a couple pieces we are waiting on. The Genright tank, sleeves, and rod ends..

Once everything shows up we are going to try and mock up the suspension with the motor still in rail for obvious weight reasons.. Then pull it and send it off to the machine shop. They do work for my diesel business, so generally they can get me in pretty quick... Shouldn't take long to port/polish the head and do the block work. Maybe 2 weeks...

I have to be done with this by the end of feb. Our drag truck has to get started... So one way or another we'll get it done in by then..

Here's some pics. We are getting close. Hopefully have the motor dressed out by this weekend and will put the cab back on and see about firing it up..


























I think we went a little over board considering it all started with a 3.5" Rubicon Express lift.....

Who makes the best full replacement body lift. We need to go up about an inch to clear the mounts..

Couple of questions for you guys.

You'll notice I have the stock belly pan on. How do I get rid of that and go with a flat plate???

Reverse lights- I haven't compared my 99 5speed to my 05 6 speed. but I think the connectors are different. Has anybody done this.

ABS sensors? Just leave em unplugged??

What type of paint stays the best on the frame? All my control arms are going to be powder coated to match the body armor. But the rest of the frame, axles, trusses, etc.. All that needs a coat. I figure just clean it, degrease it, and flat black... Just something to keep the rust off.

Anything else I'm missing from what you guys can see?? We did change out the shafts BTW to 35spline, but that can be seen from the front... Just need to see what else we are missing. I'm going to dress out the motor this week and hopefully fire her up this weekend.

Oh and we changed shocks... 14" 2.5 Ballistic Hybrids are on their way. There are 16" ones on it right now.

Dave have you received your stroker? I recently installed mine, just wondering what you thought of the performance.

Looking good man, it looks like you took some of my advice.

Body lift--go with Daystar +1" replacement pucks.

Skid plate/crossmember--look no further than Savvy. You'll want to armor that beauty up as well and there's not a better vendor to go with.

I am going to hopefully dress it out this weekend and crank it up. I sense that you are not happy with yours???

I got the Daystar kit. Thanks...

I'll give Savvy a call. I see no reason to do all this and not have some sort of smooth belly on it...

Is there a good thread about adjusting the coil overs?? We went with 250/200 springs. Which according to Ballistic was common with our weight. But we still have 0-500psi nitrogen in the shocks and of course all the diff adjustments on the outside of the shocks as well.

Be great to see a good write up on it.

I've had mastercraft, corbeau and prp, seats in different rigs. The mastercraft seats seemed to be slightly better quality but if I do it again I'll just get whichever one is cheaper.
