I am running the Rough Country radius arm drop brackets. The drop brackets are about 3 or 4 times thicker than the stock radius arm brackets, I don't have any concerns about the strength of them. I have thought about the extended arms. The recess in them would let you have a tighter turning radius without tire rub and I have heard that they allow more wheel travel. Also the bracket would not be hanging down to get hung up on.

The radius arm bracket strength issue isn't so much the brackets themselves as it is the leverage they apply to the frame when a wheel encounters a hole or tall object at speed. The impact is applied to the bottom of the bracket, which is sorta like hitting the handle of a hammer that's hooked onto a nail in a board - the nail pops out.

I thought about extended radius arms a few months ago, but I couldn't find any sold by themselves, OR that would work with 0" lift.
havack & I are considering fabbing some up using my parts truck's frame as a test bed.

Those things are BEEFY! I don't think they need to be that strong, and I think I could come up with a design that would work for most trucks NOT running over 36" tires. If I made them kinda complex, they'd be adjustable for a wide range of lift heights.

I'm just thinking out loud right now, though...

I sent that guy an e-mail inviting him to check out this board.

That's a great write-up on the custom arms. He has me sold on fabbing my own. Still think heim joints would be better than bushings, so I may go that route.

Also, he measures axle position (from axle to t-case mount) at full drop...I think I'd measure at ride height.

Let me have your ideas when you're ready too, Steve. I really like the simplicity of his design, but I haven't heard a bad idea out of you in the year I've spent here, so I'm interested.
