WCB or Duffs Radius Arms?

[OsideDave]

My Bronco has West Coast Broncos extended radius arms installed now however I just bought a nicely built complete D44 that came with James Duff radius arms. The JD arms are approx. 5-6" longer and are pretty beefy. Do you guys think its worth the effort to change out the WCB arms for the Duffs? The WCB arms are great and work fine however the Duff arms seem to be highly sought after so I am assuming they are better...?

I am still stock armed so I am jealous.....

But yes....the Duff arms are superior.

depends on what you want to do. I'm pretty positive the duff arms will outflex the wcb arms but i think the wcb arms were designed more for racing.

ive had my eye on a set off duff radius arms for a while but havent pulled the trigger. which ever set you dont use, id be interested in buying.

I have the four inch over WCB arms. The ride is smooth, plenty of travel and definitely well built. I say if your current set up works, why change?

Just lent a hand installing a set today on Dllish's rig. Wow are the Duffs arms beefy. Install was very straight forward.

Anyone else care to share their thoughts or experience on these arms? Thank you

I don't have any experience with the WCB arms....wish I did.

I do have a set of the Duffy Radius arms installed on my lifted 77'. They are built hell-for-stout, great design & engineering that works nicely, plus excellent workmanship in the product itself.

Since you already have the WCB arms on, I would just leave them on. You'd probably have to buy a new set of frame brackets, they're not easy to remove without them getting ugly. Sell the Duff arms and recoup some of your money.

If you were deciding on which ones to buy, I'd pick Duff's. In fact, I just bought a set last month. The frame brackets are on, and that's is far as I got.

I'll be getting some Duff's extended arms and WH leaf packs with shocks soon. All I see here for the end result is "better ride." Sure would be good to see hard numbers somehow to compare before and after. How much better is it?

Clearly the design works and lives, but the engineer in me wouldn't let me buy something with a section change placed right at a bend as those arms appear to have. Holy mother of stress risers!
I'm very grateful that the Bronc-up came with "Lars Bars" already installed as that design makes the most sense to me.

R those duff brackets used to mount the backside of the arm to the frame......

Yes. They come they come with the arms, brackets, heim joints, bushings, and everything you need for a simple installation. Cut the old mounts off, mock-up the new ones, double check your measurements and glue the new ones in place.
In my case I made a quick call to the experts at Duff to triple ck the accuracy of my measurements before welding them solid...so nice to get that level of customer service!

Having bent one (and continue to use it for over a year) it literally takes a HARD crash to bend it, we nose dropped the bronco off of an 8' tall wall in a competition on an obstaclel I've seen destroy front end housings, fold up links and kill tube chassis'. The real testament is that the bent arm is still in use today on a rig that gets abused mercilessly and severely tests every part under it every time it rolls out of the garage. Its owner still is a believer in the product and has continued to run the bent arm just to see what else it will take.

I am with you though I have a hard time with the bend but there is no arguing its success. And in this situation the arm giving some probably saved the front housing from being destroyed, it was a head on crash to say the least, was VERY violent.

There's in San Diego that offers a beefier version of the frame bracket.

I'd weld on an undersized heavy washer to each side of that bracket and then ream it to size, it looks a little thin to me.
