This is a very complete kit to install a 2005+ front axle, suspension and steering in your 1967 - 1977 F250 4wd highboy. It is designed to be as close to bolt in as possible and uses existing factory drilled bolt holes and rivet holes. With the right planning and preparation, this can be a one day project. The handling, ride quality and braking of your highboy will be dramatically improved going to a Super Duty Dana 60 and coil suspension.

These brackets are laser cut, cnc bent, welded, and powdercoated right here in the USA. I have spent 6 months and many prototypes designing these so they would be nothing short of the highest possible quality.

I include plates to add a 2005-07 Super Duty steering gear box. Your factory power assist won't work and a 78/79 F250 4wd steering box won't work because it will turn the  wrong way when you point the pitman arm towards the front of the truck. The steering conversion requires significant cutting and welding to the crossmember. This is the most difficult part of the whole conversion. You may have another solution to the steering box but either way the Super Duty steering box conversion is a tremendous upgrade of itself.

I have a thorough write up on the conversion process on my website. Please read through this before ordering.


Written instructions are only on my website, not printed. See this page:


A photo gallery with lots of pictures of a completed truck is here:



Included parts:

Control arm / radius arm brackets, welded and powdercoated black

Coil spring buckets with provision for shocks, welded and powdercoated black

Plates and spacers for 05-08 steering box conversion

Machined rod ends and lock buts for 1.5" DOM tube and a left hand tie rod end for the pitman arm to SD tie rod end connection

Hardware- a LOT of hardware and all high grade. For spring buckets, control arm brackets, steering conversion, track bar, control arms, etc.

Two 3/16" brake lines and flare unions for connecting front factory brake lines to SD rubber flexible lines.



Parts you need to purchase separate (all off of 2005+ Super Duty):

Front axle

Coil springs (factory height SD shocks work with factory height SD springs)


Radius Arms

Steering box and pitman arm 2005-07 only

Length of 1" ID 1.5" OD dom tubing such as TU1031 from summit racing

Rubber flexibe brake hoses

Track bar

Wheels and tires (metric pattern and at least 17" wheels)


I highly recommend replacing ball joints, tie rod ends, track bar bushing and ball joint while you are doing this project.


International Orders: 

Please be aware that my website can not calculate shipping accurately for international orders. These kits ship in two boxes, and my website calculates it as if it is one box. The actual shipping cost will be nearly double what you are seeing for international shipping. Some rough shipping numbers to expect are $350 to Canada and $600+ to Europe. Message me for a quote before purchasing.
