So i went to pick up a transfer case for the womans jeep today. And when i got to the guys place he had a few stroke parts. I saw a set of leaf springs and asked him about them. He said they were from his 03 F350 diesel. So i offered him 50$ and he took it. without knowing if they'd evern fit lol. Any idea what code they are? And if they will work? They V's? I want to do a RSK. I have 4" F350 rear blocks, and these springs. And ofcourse the d60. So what will my height be? Here's a pic of the spring code.

 

I think with the RSK and SD leafs the front will rise 4.5" then you have to add the hight the D60 will add. When I didn't my D60 swap IT added around 1.5-2 inches in the front. so you are looking at about 6 inches from stock f250 ride height. make sure you look up what needs to be done when you use the SD springs on a OBS and RSK. Im not sure what all is needed but I know there are a couple of minor differences.

 

Ugh..i really dont want 6 inches lift lol..now i dont think have to run SD springs in the rear also. I just see it as 6 inches upfront, and 4 inch blocks out back. lol reverse rake... Maybe ill stick with the SD springs and not do the RSK.

 

With a SKY 3" RSK, the D60, and those springs & 4" blocks your truck should sit perfectly level. Those are V codes... $50 is a good price!

You need the RSK to use SD springs. The SD springs are 3 5/8" longer than the OBS springs, and when mounting the RSK you need to move the
RSK hanger forward that amount.

Best thing to do is measure your stock wheel base and ensure you maintain that distance when installing your RSK.

If you havn't already bought your RSK, I highly recommend Cary @ CT Performance. He's the one that developed the RSK/SD spring mod and a bunch of other suspension mods for the OBS, SD, & Excursions. He's a good guy to do business with. He goes by Caryt or OBSWIZ on the forums.

 

Just what i wanted to hear! thanks man. Ill deff order from him! When you move the RSK forward do you have to mod the bumper?

 

Yes, you have to grind off the bumper mounting tabs & reinstall them after the RSK hanger is installed. You'll need to either shim the bumper out using big washers or notch it to clear the RSK hanger. I did a little of both so it would clear my 35's but still look fairly stock.

 

any chance i could get some pics?

 

I'm not 100% on this but I think the truck will only sit level if there are no blocks in the rear already. My truck had 2 inch blocks in the rear and when I did the dana 60 swap I put the 4 inch blocks from the f350 in and it sat level.

 

 

Thanks for the pics. that second one helped me. It looks like I need to make a Trac-Bar drop bracket.
