If you use the f250 or 350 springs from an obs it will still ride like crap. use SD "v" code springs for a much better ride

1 Buy a SKY manufacturing RSK, it is about 200 cheaper than ORU
2 a RSK with stock 350 springs is all you need to fit 35s
3 If you want a better ride do the RSK and "V"code superduty springs
4 if you use the F250 springs it will ride worse than your buddys F350 w add-a-leafs

Here is my 97 F350 w a RSK, stock F350 OBS springs and 315/75/16(35")on 16x10 wheels

 

3" shackle reversal kit, SD springs front and rear, OBS F350 stock anti sway bars front and rear. I opted to use air bags on the rear for carry capacity rather than over spring pack overloads. Handles and rides wickedly....also should speak with OBSWIZ, CaryT and get special valved Bilsteins shocks too....

IIRC 42" from ground to center of fender arch (measured vertically though center of hub) on the front and about 41" on the rear on sig truck below..

Anyone go t a PN for the V code springs?

 

I have EVERYTHING needed to do this mod..FYI I developed this 8-9 years ago and have helped countless OBS owners get the best possible ride quality from their trucks.

PM me if I can help.

Sky rsk kit is the best. Real good thick shackles and easy to put in. I didnt do the SD springs but to me it was a big difference in the ride. I have an F350 and all i did was the rsk in the front and it sits pretty much level. I also an running 305s but you could easly run 315s no problem.

 

to make use sd v code springs, do you need to do any mods or do they bolt right up?

 

Need to push the spring eyen on the RSK approx 4" forward due to the fact SD springs are 4" longer

 

i juSt got done with mine, D60 with superduty springs, "v" and "b" codes, 4" rear blocks, and 35" tires. The OBSWIZ SUPER DUTY CONVERSION.

 

You notch the bumper?

 

4DOORSHORTBOX you need to fix your bumperoke:

 

Just a FYI its not 4" so please contact me first to learn the correct procedure for the RS-V code installation.

 

So I'm gonna have to keep my 4" blocks eh to keep it 4".....

I was under the impression the rears would be tall enough with B-Code springs. I don't wanna be half ass clearing 35's, I need the articulation out here and I don't like the look.

 

V and B codes 3" rs kit and 3.5" blocks clear 35" and is level!

You don't have to keep your blocks we can set you up with Deaver rear mini spring packs..ride great and then just use a F250 block. Or use X codes with a 5" Icon rear and no blocks...

 

Billy, he knows..FYI I drove mine for 150k with the springs on backwards.

 

Ok, so i know my bumper is not straight, I fixed it, and yes I notched the bumper around the spring hangers. I will be mounting a Reunel bumper on the front with a 12,000 winch, they are not to far from me, and they will have to make custom mounts to work around the RSK. As far as the springs, yes I know they are backwards, there were a lot of colorful words being yelled in the shop when i realized i had done it :doh:. I call the expert, Cary, and he said I would be OK. I ordered new shackles and will be doing the flip here shortly, I am just enjoying the smooth ride in my truck too much.

 

Does it shove the axle too far ahead?

 

Properly installed the axle stays in the orginal location.

 

Yeah but the springs are installed backwards. The centering pin is not centered if i am not mistaken

 

Brad I give up, hope you like your suspension.

 

I get what you are saying Cary, i guess i just dint get my thoughts across in type quite to well:doh:

 

Wow you guys don't get it! :doh:If the springs are 4" inches longer, they are 4" longer. You have to move the hanger forward to make them fit.

 

I had this conversation with a friend the other day and he couldn't figure out how I could put longer springs in without moving the axle or the rear hanger:doh:

After what I found to be a way to long conversation, I had to draw him a pictureoke: he finally got it.

I guess some people have a hard time with our OBS springs having a "center pin" thats not in the center of the spring

 

what for tires are those? Dunlop Maxx traction. They are quiet going down the road, no noise at all.

 

I just looked at SKY Man. there are two options on the site. Can someone please point me in the right decision???

First Option, $270.00
www.sky-manufacturing.com - 9297F250F350FordOBSSuperdutyAxleLeafConversion

Second Option, $369.00
www.sky-manufacturing.com - 9297F2503503inch4x4FrontShackleReversal

They look the same to me, the front end parts that is...

I think I will do the SD rear swap later on...

 

Check out Precision Metal Fab, he has a bolt-on RSK that the guys like. It was developed after this thread started.

 

:whs:

Go with the PMF one. it is FAR superior to the SKY part

 

Looks like that is the route I will take. I will have to get the D60 swap done then do the SD swap later on. My TTB is getting worse by the day!
