You gotta run a steering box and we plan to do cross over steering, so that's the reason we are doing 3-link & panhard. We didn't want to get into the craziness of running bellcranks or other options to be able to handle a 4-link without lots of bumpsteer.

Check this out starting at post #135. It's slick as it gets, but lots of extra parts to fail, and lots of engineering to make it all work out.

Makes sense. Mine works fine for what I do but the upper sure takes a beating.

Yep, been running the same link setup other than link on the other side for 6 years. Hopefully we can keep it together. I've been running the same set of 3/4x5/8 rod ends for that entire time, so I'm hopeful we can keep it together if we keep an eye on it.

I didn't get out to the garage much this weekend, but I find some time to check out builds of TJs with the fronts stretched out. I'm thinking it might be worth it after all.

Here's the axle sitting at what could be full bump if we don't push the axle forward.



Stretching 2" forward gets at least another inch of up travel, maybe more.

Oh, and it looks like the Wag pitman arm should provide plenty of swing running knuckle over on the Ford D60 knuckles. When I first did my d60 swap I ran a drop TJ arm, and it severely limited steering. The Wag arm has minimal drop and enough length to not have the bad steering issue.

What's your current/old wheelbase John? I'm at 104" and would go another 2-4" if I had it to do over.

Any chance you could tell me how long that waggy arm is? I'm wondering if that would help the steering on yj box?

Wheelbase on my TJ was 106" before we pulled it all apart. Shooting for 110" for this build. The Wagoneer was 109" so we know we can handle that size on the TREC courses, and the extra wheelbase helps with smoothing out the whoops. Jesse's buggy is 110" and it climbs well and is stable.


I can double check, but i think from hole to hole it's around 7". I believe WhiteRhino is using an astro box and arm, maybe he'll chime in if he's losing any steering with that one, too. It's even flatter than a Wag arm from the pics I've seen.

Whoops. The front of the frame fell off. This should help get some front frame stretch by rotating the steering box. The frame rails will be replaced with 2x3x0.125 and the front bumper will be 2x4x0.125. Extra crossmember will be added for antirock style sway bar.



I picked up an Astro box from a yard by work to see if we could package it similar to White Rhino's, but with how a TJ frame pinches in, it put it into the side of the of power steering pulley. I'm thinking we will be keeping the Wag box, but may move to the Astro pitman arm.

Sharp - it looks like the Wag is about 6.5" inches from center of pitman arm to center of sector shaft, and the Astro is about 6".

No, what's with the durango box? I did a quick google search and it seemed everybody wants one, but no one knows why.

We were thinking Wag box since we have one, it's a 4-bolt box instead of 3, and we know it worked last two years racing the Fat Pig. But if there's something to it, I'm open.

Quicker ratio, stronger assembly, bolts right in place of a TJ box. Pitman arm faces rear.

Edit:
"The Durango box is not stronger per say but does have a larger piston . The turning is different too . The ZJ/waggy box is 3-3/8 , the Durango box is 2-15/16 "


Meh, like you said, what you have works, why mess with it

I finally got some time in the garage tonight after a busy family weekend. I put together a simple front bumper out of 2x4x0.125. It's 42" wide, or about the same width as the grill.

I decided it would be easier to tack the frame extensions on the bumper, add a temp cross member, square it up on the bench, and then install it as a unit. I was able to use the some reference marks from when I squared it on the bench and some on the frame to get it squared up in relation to the frame.

I just have a few tacks holding it for now, I figured I would sleep on it before adding too much weld.





So after all that, the top of the frame is 1.75" inches higher, and we gained 2.75" under the frame since we moved from stock 2.5x4 to 2x3 tubing. I extended the frame out an extra 1/2" for steering box clearance in addition to moving to 1.75 tube for the swaybar mount/cross member, so that should give us 3-4" of front stretch.

I made the outside of outside frame rail 32" to make the transition between old and new frame easier, so we narrowed almost 2" over stock, but only 1" narrower between the rails. I weighed the chunk of frame we cut off and the new parts, and that comes out a wash at 30lbs.

Big thing to see will be how much extra up travel we gain.

How time flies around the holidays. I've spent more time staring it at trying to figure out how to make it all fit, and made up some steering box brackets that I have to do final fitting on.

We did finish off the Wag over the holiday break.
