I am getting a little closer to installing my ford KP 60 and I need to purchase my upper arm joints. I will be running a single passenger side upper arm with a ballistic adjustable frame bracket. Problem is, space is running low and I'm unable to run a JJ on the frame side due to it's 2.63 width hitting the starter.

I work across the street from summit machine, and Mike can build me a jimmy joint that will fit perfectly. However, I will be relegated to running a 7/8" shank on my upper arm.

Do you think this will be a large enough shank for a TJ 4.0 at on 60s and 42" MTRs?

Thanks in advance,
Marcus

For an upper yeah you should be fine.

Thanks for the reply.

I stopped by Ben Hanks Racing here in SLC, and they recommended cutting and tapping a 1.25 .375 wall upper for 7/8. If it works, cool. It's going to look a little puny compared to the 2" lowers:D

Marcus,

Are you going to run a 14 bolt rear maybe a stretch? What are your planned mods.

Marcus,

I'm stretching it from my current WB of 100" to 110-111". I also have 70U going underneath and 42" MTRs will be the shoe of choice.

I am trying to keep my 3.5" Front & 3" rear coils for a super low COG which is what is making it so tough. I'd kill for some undercarriage pics of one of Chris Durham's rigs.

After I get it wheeling, I'll have someone boatside it and install a durham hood and grille.

Tim's rig used RE coilbuckets that had offset coils with no highsteer, then full hydo. Tweeba's is the closest so far.

BTW, is this Ceeko?

7/8 shank is plenty strong enough. I ran a 3/4 shank on mine. Only reason for a bigger shank on the lowers is because they see impact forces from rocks. The upper arms are 100% tension/compression if its set up correct with no binding

ATXZJ,
Do you have a build thread going anywhere for this episode of your build?
Your one step ahead of me...again.:p

Yup thats me. Have you checked out Kirbys build? Sounds like good on the build. I just paid mine off Friday so soon I should have a bit more cash to do what I want to with it.

If you are going to tap .375 wall DOM, I would suggest using 1.75" solid 7075 and drilling/tapping it. You can get it for $10-15 a foot, and its plenty worth it! I finally converted all my links to aluminum and besides the weight savings and bling, they are tough as hell

Don't worry, I got a head start and then fell on my face. Had to get going again as all my wheeling buddies seem to be running 40" stickies and I still had 35:(

BTW, your rig is looking sweet!

Thanks, that's what I was thinking but needed to hear it from a few others.

BTW, great build!

Nice, good to hear you're still wheeling. Did you make it out to Krock before they closed it?

OK, I check RME a few times a week and missed it somehow. :homer:

Thanks. (for the compliment too)

Thanks for the feedback guys. I ended up going with a 7/8 jimmy joint on the frame side and a 1" johnny joint on the axle side while using a 1.75 .250 single upper. I'll post some front suspension pics up tomorrow.

Picked up some bling from Mike @ summit machine yesterday. He was able to build three Jimmy Joints to the exact specification to fit my existing brackets. With these, I can now finish my front suspension. I can't tell you how cool it is to have a shop in town that can produce this kind of product
