DOM Radius arms

[RajinCajun]

Well got the passenger side arm finished up, just need to grind off the fresh paint and weld on shock tabs . Will take some pics of driver side arm build and gear install. I know plating the sides is overkill, but I wanted a custom look so here is what I came up with .

looks good, was that a leaf spring axle??

Hey those look really nice! Will they clear your tires with no bend in them?

 

[RajinCajun]

It was a coil sprung axle from an 05' F350, it had a huge stamped steel radius arm.

Yup crawln, they clear with about 6" of clearance with the 36's, so the 39.5's should fit fine.. I hope anyway

Couple of questions RC and please don't take this personally:

It doesn't look like your RA design allows for any caster adjustment. Am I missing something?

It looks like you don't get any 'wristed' action using the stock cast axle mounting points. Why didn't you incorporate this into your design?

Nice work though, those arms look beefy!

No problem. I personally don't like the idea of my entire front axle on one side being held on with one bolt, which puts all of the stress on the other RA. I play in the mud quite a bit and don't want to worry about hitting a stump with the front axle and having it break the single bolt and then I am stuck. I know it limits my articulation, but I am willing to forgo that in the favor of strength. For the caster adjustment, I thought about it alot and almost did it, but then realized how often do you adjust it? Why spend quite a bit more for an adjuster of sorts, heim etc.. just to adjust it once or twice in its life time... I built the prev RA's and noticed I didn't have it set exactly right so I just rotated it a little before I built the current arms so it should be perfect now.. if not I am thinking it is close enough for the minor highway it will see..

Hey R.C. Your radius arms look great! I am thinking you didnt want to carry them around the shop much! LOL. On mine I have 40" MTR's on 10" wheels with 4 1/4 inches of back space and clear the arms easily. Looks great!;D

 

[RajinCajun]

Thanks for the compliments.. Yea, they are pretty heavy.. quite a bit of overkill, but that is my middle name

I thought the coil sprung Super Duties had the bushings mounted in the radius arm??

 

[RajinCajun]

On the 05's the rear of the radius arm there is a bushing, but the front end bushings are build in the axle.

We Think alike on the overkill. On my lower tube I interference fit a peice of 1 3/4, 1/4 inch wall inside it. If I bend that, I will have had fun that day!!:-[

 

[RajinCajun]

I thought about doing the double tube set up, but after I actually wheeled Katemcy with .120 wall tubing and I didn't bend them even dropping down on them a few times I figured I would be ok with the DOM and some plating

Left arm done, Detroit and 5.38's in front axle, rear still under assembly, had to get a different rear pinion bearing from a 10.25... should have it in tomorrow and back together.. Here are a couple pics..

 

[crawln68]

Mmmmmmm, I like shinny new parts! ;D

Well Radius arms done, shock mounts done, 5.38's installed, Detroit installed, diff guards built and done, new BC Broncos throttle cable done.. Transfer case swapped with spare because of bearing wobble, just need to redo the rear shocks and build a skid plate. Man I am almost ready for the Spring Round-Up at Katemcy
