JBA long tube headers with Duff extended radius arms?

[RB70bronco]

So i am trying to figure out if these 2 parts will work together. Cant find much info to confirm either way From the pics i have seen they look like they will work no problem. When I first installed the arms I had to remove my L&L ultra flows they where in the way by about an inch on the drivers side They really stuck out that way compared to the JBA's . Any info will be greatly appriciated

Back to the top. No idea, but curious what others say about fitting with updated radius arms.

Another bump

Do you still have the L & L headers? Any way to go through the process of cutting and modifying perhaps?
Or even if you don’t have a welder or that kind of skill, maybe there’s a local shop that could do it for you without too much expense, if you can lay it out for them.

And I’m guessing that, for some reason you are averse to using shorties?

Don't know what "JBA' means but I have Long tubes with my JD extended arms and they work great. The exhaust guy had to be creative to let the pipe get by where the long arms connect to frame because its right where transfer case is located.

JBA is a brand-name.

I was thinking heat em up and bend em a little if they don't clear. Watching this thread. I plan on upgrading to duffs arms for tire clearance and prefer long tube headers for more low end. The shorties aren't much different than stock manifolds performance wise.

I bought mine thru yall and had no issues. They are connected to a 351W which is slightly wider than a 302/289.

I don't know if OP was worried about the long arms clearing when they articulate but haven't run it that hard since installing.

I have them on mine with no issues, also a 351

Automatic or manual transmission? My long tube header (not JBA) hit the clutch linkage with the 351W.

351W with long tube headers, manual 4 spd, Z-bar hit headers.

Bent Z-bar for clearance, been driving for decades with no issues.
