This is a very complete kit to install a 2005+ front axle, suspension and steering in your 1977.5 - 1979 F250 4wd pickup. Please note the mid year change. The earlier 77 trucks have divorced transfer cases and in cab fuel tanks. This kit does NOT fit the earlier 1977 F250 trucks commonly called highboys. This kit should also work on 1979 F350 4wd frames.
 
This kit is the result of many hours of 3d scanning, engineering in Soldiworks, prototyping, real world testing, and fine tuning. Every aspect of this product's creation and manufacturing is done right here in the US. 
 
 
Important to Know:

This kit requires temporary removal of the driver side engine perch to drill holes through the engine crossmember and the frame rails. Drilling tempaltes are included to take the guess work out of it.
 
A decent amount of drilling is required for the engine crossmember, track bar bracket, and spring buckets. Check out the instriction page.

No cutting or welding of your frame is required. Welding tubes ends on a piece of DOM tube for the steering drag link is required.

The SD steering box will likely not clear a factory super cooler radiator. These radiators extend further down than others. The more common radiatos clear without issue.

Radius Arm Bracket Variations. 
I have found at least two frame variations requiring different radius arm brackets. The supercabs and the single cabs each have different frame contours. I have not tested crew cabs, I believe they will take the single cab radius arm brackets but please know this is not well tested. If you have a crew cab, feel free to reach out to me to get a template for testing before you order.
 
Besides the frame type, I make each radius arm bracket type in two different heights. The larger bracket holds the radius arm pivot point lower to accomodate lift springs and maintain correct caster. These are good for a 4" lift spring.

Aftermarket radius arms can be used with either of these brackets, but if you are using caster correcting radius arms, go with the smaller version because you won't need the additional caster from the brackets.
 
4 Link Otions:
As an alternative to radius arm brackets, I have a two different 4 link kits that mounts in the same holes on the frame as the radius arm bracket. This can be purchased with the front end kit or at a later date.

The "low lift" option has the upper tubes attached to the side of the frame rails, and the tubes are formed into an "S" shape to accomplish this. This gives you a good amount more ground clearance than radius arms. This works well with oem used SD springs or 2" lift springs. You probably could use a 4" lift spring but I havent tested it. Note that even though these are called "low lift", they have no effect on the height of the truck, they just work well with less lift.

The "high lift"  link has all 4 tubes mounting under neath the frame. It gives ground clearance similar to Super Duty Radius arms and accomodates a wider range of heights. It pairs well with oem used SD coil springs, 2" lift springs, 4" lift springs, and 6" lift springs (although I have not actually tested with 6" lift springs).
 
Ride Height
 
I expect this kit to raise your front end about 2 to 3" when used with used oem SD coil springs. Pictures and measurements to come.
