This is for all you bronco guys on here. Cough! Cough! Jonski and Roughshod Cough! Cough! I thought you guys might appreciate these.
My customer wanted some indestructable radius arms for his bronco so this is what I came up with. The upper tube is 2" .250 wall DOM, the lower is 1.75 .120 wall DOM and they're plated with 3/16th. I used about 16" of the factory arm and sleeved the 2" over it then boxed it all it. They use a 3" forged ballistic joint with a 3/4" bolt. I'd say they weigh around 60 or 70 lbs each.

from the title, I figured there would be bacon.
 
Next set you make bend them a bit for tire clearence. Nice metal work!
 
They don't need to be bent for tire clearence. I thouht they would too. After a little researching all the long arms out there that were bent for clearence. I learned that the reason they were bent like that was so the end would fall under the frame. Factory arms taper together towards the rear and they pivot under the frame. When you extend them longer they end up inside the framerails which means the companies would have to build a pricey crossmember to mount them. Just about every company out there just makes a simple bolt on pivot bracket at the frame and bends the arm out to line up. I wanted something stronger so I built a crossmember.
 
Still think you should have wrapped them in bacon
 
lol, looks like you may be the bronco world's new radius arm guy since cage went out of business.
 
yeah, i didnt either till seeing your post reminded me i needed to check pricing on a crossmember...went to their website and got nill.

Looks like you gotta shot here to do something big, lol.
 
What did you do when you welded the cast steel? What type of wire/gas?
 
I used just plain ole er70 and c25. Seemed to work fine. They are supposedly made of true cast steel so I didn't really need to preheat plus if you heat too far you risk messing up the composition of the metal and making weak spots and I don't have any way to heat them accurately to 450 deg. So I went with it.

What!? I have to say I am not suprised. A half wit monkey could get better service than Jim. To get my arms I finally left him a voice mail " Hey man I want to spend $1000 with you if you would like to return a *^%$*& phone call"

He sent the wrong mounts 44 vs 60 and that took over a month. Great product, shitty service.:rolleyes:

West coast broncos are the guys that make this kind of arm, not cage. For what it's worth.

Jim seemed like a cool enough guy when I met him, must have started sucking at business though. CAGE isn't gone though, just renamed.
 
Nice beef there. I do like my Cage arms, but as has been previously noted, they aren't around anymore. Id like to see those in action out on the rock pile by your shop!
 
Well you probably won't ever get to see them on the pile. This customer is more of a 4x4cross and mud guy. But when the bronco is all done I'm sure we'll atleast flex it out on the lift to see what it'll do
 
They look good. I would think that you want the 2 inch 1/4 wall as the lower tube and the smaller thinner tube up top. That way if it hits anything the heavy tube is taking the blows.
 
They turned out nice. That 3" joint looks small on those things. They must be pretty big. I heard that Cage was in the process of being bought, not defunct. I do know that no one can get anything from them right now. From what I have gathered, the Cage arms and the Duff's arms are exactly the same, though I have never compared a set next to each other.

I agree. The only reason I did it that way is because this truck's never gonna see any rocks other than whats in a race course and its looks cooler. If it were for crawling then definitely it would be a thicker lower tube.
 
Our mutual buddy from Advance (Big Jeff) told me you wanted to sell the S10 blazer. I rode by to take a look and the dash and engine was out. Just curious if you want to still do something with it.
