Sweet you won't be disappointed with your choice, but I would strongly suggest you move those upper coil buckets out on the frame to the f150 coil width, it will ride, handle and drive much better than the eb suspension width, trust me, I've been through suspension and chassis design classes in college, the closer the shock, control arms, and springs are to the wheel, the more control it has over the wheel's oscillations |

That's the plan. I need to figure out whether the spring mounts I got with my long arm kit are for EB or full width. I've got a set of spring mounts on my shelf from a full size Ford something or other as well. |

Spring mounts on a full size are the same depth as eb, it's the frame that's wider, I had Clint cut mine out to where they are sticking out 1.75"s more per side than stock eb, most people do 2"s per side, like I had said earlier, if you'd like to drive mine on the 17th you're welcome to |

Corey, thanks, I may take you up on that. Gunni, yeah. I'm pretty stoked. Now to find a matching 9". |

Yes and leverage, think of it like a hammer, if you choke up on the handle you have a lot of control, at the butt end of the handle not so much |

No, unsprung weight is (basically) anything below the spring. So less unsprung weight would be a lighter wheel, tire, control arm, etc. Decreasing unsprung weight can have a major impact as the suspension has less mass to damp, allowing tighter control of the wheel's movement over bumps and improved traction. It's part of why IFS handles better than solid axle-less crap swinging around. There are also issues of camber change and some other stuff than has pushed the move, but weight is a contributor. Corey, feel free to correct me if I've gotten this wrong. |

Nope you got it right, sorry I said yes up there, I skimmed through Chad's response as my wife was showing me something, but my reference to a hammer still stands correct, and with camber change on ifs that's only really with SLA setup(short upper arm, longer lower arm) twin I-beam or with machpherson strut setup, all of these designs change camber at different rates throughout suspension travel, but that's another topic, but no matter what suspension type, having the spring and shock closer to the tire translates into ; as you stated Justin, tighter control over the wheel, but reducing unsprung weight is a good idea as well, unfortunately you'll be drastically increasing it with the 1/2" thick tubed FW d44, I would strongly encourage you to change to aluminum wheels, and a strong properly setup set of Bilstiens |

Cool, both those explanations make sense to how a suspension works. My 79 axles don't have the thick wall. After my axle swap I changed from a 10" wide aluminum rim to an 8" wide steel rim. I can't say I've noticed much difference. But I'm still running on bowed coil springs, and whipped, cheap, 15+ year old shocks. A set of Bilsteins are in my future for sure. |

There ya go!! You need to at least weld the tubes to the housing. Mine leak continually after some hard wheeling. They didn't spin, but the seal is broken. The plug welds need filled up too. I truss isn't a bad idea. Oh and that inner axle seal is a pain. I assume you're going to reseal/rebuild this beast before you go together with it? Any leads on the rear? I mentioned mine was from a '77 Lincoln. It is a HD version with discs. Maybe something to consider. |

Thanks for the tip, I can make those welds. It'll be good practice. I am planning a rebuild, since I need to swap my ARB and brakes onto the new 44. Thought about a truss, but I don't want to lose clearance since I'm considering bumping the front axle forward an inch or two and am concerned about the crossmember. Need to get it mocked up and go from there. The rear will almost definitely get a truss. One lead from Jason, will need to follow up on it. I'll probably look for one that's in the 63-65" width range as there are some minor handling benefits to the rear track being slightly narrower than the front. If I can find something like yours with discs on it already, that'd be a bonus, although I'm not sure there are many 1/2 ton axles out there with them. I may go up to Andersen's in Greeley and see what I can find, they tend to have older rigs than the yards in Denver. |

I pushed my axle forward 2" when I did the new arms. No cross member issues. It's mostly steering and track bar interferences. But way back when my drop track bar bracket decided to can-open my frame, I pushed the new reinforced track bar bracket at least an inch forward anticipating this stretch. But again, my pumpkin is more centered then yours will be. |

How did you deal with the various interferences? Sounds like some bump stops will be in my future. |

| Post subject: | Re: EB vs. Full width |
I doubt you'll need bumpstops with 3.5" or more of sl, as far as shocks go I would buy some f250 shock mounts, mine were $11 a piece from ford when I worked there, and then run a 14" travel long body shock, I'm currently running the 14" travel duff shock because it was only like $32 per shock and it works well, if you can't swing for bilstiens I would rec. it |

The kit I got has adjustable shock mounts, sort of a shock version of the adjustable spring mounts you've got. I donated my F-250 mounts to Project 33x2. |

My springs are super stiff, so I don't have a need for bump stops now. There was a slight interference with my cross-over exhaust passing under my oil pan, but that is, uh, well self clearanced. I do have a bolt on my ram assist that scraps by my GLO diff cover, but not enough to worry about. Other than the body, I think your biggest intereference will be steering and track bar stuff. With the help of a buddy, I made a variation of this that serves both as a track bar mount and ram mount: http://www.polyperformance.com/shop/Syn ... -1701.html That allowed me some extra clearance. I have the F-250 mounts and my shocks limit my droop right now. I want my shocks to be mounted higher eventually. I can see myself making new coil buckets with built in shock mount. |

did you need a cherry picker? My buddy has one for sale. 100 bucks |

I do, but am trying to figure out if I can justify the hundred. The bronco fund is badly depleted. |
