I ripped out the problem-matic TTB D50 and put in a 95 Dana 60, a RSk and SD V code springs. This coming weekend the 315s will be going on. Here is a link to the RSK/SD combo with the Dana 60
I started with this
Sagging front springs, beat ball joints, bad u-joints, destroyed pivot bushings, worn rotors, shot brakes, you know, your typical 100k+ TTB
So i did this
After the axle was removed, I removed the pivot brackets, leaf springs and shackles.
I then spent about an HOUR AND A HALF cutting off the bumper brackets
Ford welded them on all 4 sides(top, bottom, front and back)
Next up is prepping your RSK to be mounted in the Forward location to use the SD springs
I cut the bushings out of the inside(2 small welds per bushing)
What i cut off
After is was cut off
next up is clearancing the RSK for the Military wrap of the SD springs. I removed 3/8" others have removed less, i just wanted to be sure the springs would clear.
Next is mounting the RSK in the correct location for the SD springs.
Cary wants you to check the center point of your front axle before removing it. But mine was already out by the time I got that info. SO I just mounted the RSK forward 3.5" of where it would of went if I was to use OBS springs.
Should be able to see my scribe marks
After it was clamped in place(3.5" forward and the 5/8 hole still the same height as the original shackle hole) the 10 needed holes were drilled.(4 5/8" and 6 1/2") Pay no nevermind to the 1/2" bolts on the inside of the RSK in the most forward position(dont drill those holes, your bumper brakes will be going right over those holes)
After the RSK was in place I drilled out the spring holes to 3/4" and the military wrap end of the spring to 3/4". (you need to buy (2) 3/4" x 5.5" grade 8 bolts with nuts and washers)
Also I drill out the wide end of the shackle to 5/8" to match the other end of the SD spring. (you also need to buy (2) 5/8" x 5.5 grade 8 bolts with washers and nuts here too)
Next was to install your SD springs. Before I install ANY leaf springs i thoroughly coat the spring bolts with anti seeze. Put the springs in place but DO NOT tighten the hardware YET.
Install your track bar mount and track bar drop bracket (if you are using one)
Roll the axle under the truck and U-bolt the springs to the axle.
After you have the axle u-bolted to the springs you can lower the trucks weight onto the axle. You can NOW tighten your spring to hanger hardware. Install your steering linkage . Install your brake hardware. Install your new shocks.
Roll the truck forward and backward about 20 feet or so a couple times to center the axle. Now you can connect your track bar to your mount(axle side and frame side). I did NOT use a track bare drop bracket in fear for contact with the sway bar. I just used a SKY adjustable track bar and it works just fine.
Had to cut and weld the bumper brackets back on
If you notice, the mount is about flush with the front of the RSK crossmember. This will give you enough clearance to mount the bumper and NOT have it hit the crossmember. I notched my bumper to clear the actual spring hanger of the RSK. I cut 5"wide x 3"deep.(but i only needed about 1" deep)
As you can see, i cut too much out of my bumper
And you can see the mount(the flat piece that bolts to the bumper has about 1/2" clearance from the RSK crossmember
Next up was the rear. I bought a Ready lift 5" block kit for a 99-05 SD
Install is just a matter of swapping out the 2.5" blocks for 5" blocks. I cut about 2" off the u-bolts so i could tighten them with an impact wrench. Also intall new shocks at this time.
And here is the finished product. i gained 5" of lift in the front and 2.5" in the rear. Now i just need to get my new tires and wheels
The ride is better, but i cant really say how butch better. I wish i had another STOCK CCSB to hop into now that mine is done. But my back seat used to rattle going down the road now, it is quiet
You also have to take into effect, I took out original 148k shocks , springs and worn bushing and put in new front springs and 4 new shocks.
There is roof for an intercooler just in the fact that the RSK is pushed forward 3.5" when using the SD springs. The intercooler would mount behind the RSK crossmember.
Currently the truck has 285/75/16 on the 16x7 wheels. it will be getting 315/75/16 on 16x10 wheels
O yeah. Forgot. Here is a pic next to a STOCK f350. Mind you the CCSB has 285s and the yellow truck has 235s but you get the idea
A parts list for a Dana 60 swap into a F250
One of the following FORD Dana axles, it is your choice.
85.5-91 King Pin Dana 60
91-94 Ball Joint w pin on calipers
95-97 ball Joint w bolt on style calipers
The t-case yolk
if you have a 1356(80's-95) you will need a yolk from the same vintage f350 to use the F350 front drive shaft.
If you have a 4407(96/97) you will need a yolk from the same vintage f350 to us the f350 the front drive shaft
THEY ARE NOT INTERCHANGABLE
Next. A RSK. You can go with a SKY manufacturing or a ORU(off road unlimited). For the SD spring swap I used a SKY one, I would reccomend a I/C version even if not putting a I/C in for bumper mounting reasons.
Then you need a set of SD springs. casting numbers on the springs are not a big help. Your best bet is to look at the spring code sticker in the door jam of the truck they came out of.
I used "V code" springs part 2C3Z-5310-HA
An adjustable track bar is a good investment(especially if using a anti-swaybar) SKY sell this. And i use one instead of the Track bar drop bracket. I have Very little bump steer if any.
Shocks. It is up to you on what shocks you run but Bilstein shocks give the best ride.
Front 33-185552 / F4-BE5-6248-H5
Rear 33-185569 / F4-BE5-6249-H5
Stainless brake hoses(may be able to reuse your brake hoes but mine were 145k old so i bought new longer ones
Additional hardware you will need to buy because The SD springs have different spring eye diameters than the OBS springs(sky gives most of the necessary hardware to mount the RSK. ( I suggest all grade 8 and SAE washers) But if you plan on bolting it in(not welding at all) You need to buy
(4) 5/8" x 1.5" bolts, 8 flat washers and 4 nylock nuts
For the front spring eye you have 2 choices
1. go to for and pay about $25 each for the 18mm nut and bolt
2. go to a hardware store and buy store and buy (2) 3/4"x5.5" bolts with 4 flat washers and 2 nylock nuts(about $18 for it all)
For the back of the rear spring(where it attaches to the shackle)
You also will need (2) 5/8"x5.5" bolts with 4 flat washers and nylock nuts.
As long as you have 2 reusable bolts from the old springs you can reuse those to attach your new shackle to the hanger(the one under the front cab mount). If not you will need (2) 9/16" x 5.5" bolts with 4 flat washers and 2 nylock nuts
Next would be track Bar mounting bolts.(SKY kit comes with this but only grade 5)
(3) 1/2" x 2" bolts with 6 flat washers and 3 nylock nuts(you may have to trim the end of the far right bolt) it may be close the pan.(I trimmed about 3/8" off mine)
I bought 2 new bolts to mount the track bar. Axle side is 1/2" x 3" and truck side is 1/2" x3.5" Also get 4 flats and 4 nylock nuts.
If using a anti-swaybar you will need (6) 7/16"x 1.25" Bolts, 12 flats, and 6 nylock nuts to attache the brackets to the frame. You will also need (2) 1/2" x 2" bolts with 4 flats and 2 nylock lock nuts, to attach the endlinks. If you did not get the drivers side axle attaching hardware you will need (2) 1/2"x 1.5" bolts with 4 flats and 2 nylock nuts
U-BOLTS. Alot of people reuse u-bolts. They are NOT designed to be reused. You will need (4) 9/16 x8"x3" squares. Jeff's bronco Graveyard has a set for about $35 but you will want to trim about 1.25" off of them.
I believe that covers all the hardware, IF not please post up what i missed.
Rear 5" blocks. I bought Ready Lift ones, because they have the wing for the bumpstop built in like the factory.
The only real "speciality" tools i needed to buy was a 3/4" and 5/8" drill bits to enlarge the front spring hanger and eye(3/4) and the spring end of the shackle(5/8)
