This is a very easy install and cheap wy of gaining lift.
The kit come with everything you need, the new hangers, grade 5 bolts washers and nyloc lock nuts. http://www.superford.org/getfile.php?id=116008&toggle=fullsize&f=Dsc00158.j pg[/img]
first things first youll need to get some paint on the hangers I used automotive primer and flat black paint from a rattle can
A couple of tools that will make your life easier are an air chisel, impact wrench, and a grinder.
The first step after painting is to make sure you have a safe work area
If you dont have a set of those things above BUY SOME they are only 25 bucks and mine are 6 ton stands
Once everything is up and secure you are rady to begin removing the old hangers.
First thing is to remove the axle and rear springs to give you a little more room
this is where the impact wrench comes in those bolt can be difficult.
Once you have room to work it is time to remove the old shackles. They are rivoted on so you will have to get the rivots off. an air chisel works but there is ample room to get a 4.5 inch grinder in there so whatever is convienant for you I like spark so here I am
Once the rivots are all ground off I used a shop hammer to knock the hangers off of the frame and a round punch to knock out the rivots.
The Sky MAN hangers are designed to match the original bolt holes but you will need to run a 1/2 inch drill bit through the hole to ream them out so the bolts fit.
This next part I didnt get pics because I found out I needed a new gas tank and was Pissed sorry guys.
To boly the hangers on you will need to drop the gas tank so you can reach the inside of the frame. This is pretty sinple there are about 6 bolt on the front and rear of the skidplate. remove them and the tank will drop enough to reach the fuel lines disconnect them and move the tank out of your way.
after that simply bolt the hangers through the existing bolt holes make sure it is torqued down and replace the springs on your truck.
Reinstall your gas tank,and axle and youre in business. remember to bleed your brakes when reattach the brake line to your axle.
I didnt reuse the factory ! inch block and my pinion angle is near perfect. The flip does also move you axle forward about 1 inch.
Here is a base line of where I started this measurement is with the factory block
and here is the end result WITHOUT the factory block
Here is a comparison of the factory hangers and the sky man hangers notice tha difference in thickness
This flip can also be done with hangers from a F-250 or 350 but for the price ($150) shipped to your door These are well worth it they are well made very beefy and you dont have to go to a junk yard and spend all day removing them.
