Hey guys, I am getting a 3inch RSK kit for my truck and am wonder what I absolutely need?

They recommend longer shocks, but I just got new KBY's and they are pretty good. Do I absolutely NEED longer shocks?

How about the drop pitman arm, can I get away without that?

Thanks!

 

Did you Dana 60 it?

 

Nope, I don't have 1K laying around for that.

 

Don't think the rsk will work very well then ? I think one guy here was trying to do it on a TTB but wasn't going very well and never finished ?

 

Here is a write up on it here.

Reverse Shackle

I just need to get a drop bar, oh well, the sky guy said I won't need the shock or pitman arm.

 

Sure enough lol I wonder how it will ride? Better or worse then lift springs you think?

 

Dunno,

I also need drop bracket which are a extra $200. Arggg.

 

If all goes well tomorrow, I will have a rebuilt D60(balljoint), steering links, 350 leaf springs, brake hardware, from a 97. everything for $375.....we will see.

 

i think youll be better off with the d60 instead of the RSK for the TTB!

 

Ok, thanks coal. any idea on how much lift a D60 gives?

 

Wasn't it like 4" minimum to clear the oil pan? Or something like that....

 

When I put the n d60 in mine this past summer I didn't have to lift it at all. Otahyoni came and got the d50 ttb front. I still haven't figured out why everyone says it needs to be lifted to clear the axle. I also used the f350 springs so maybe that made the difference idk. But I do know that those springs didn't lift me up another 4"s lol.

 

Not how much lift I need, how much lift will the swap give me versus the d50?

 

I think the D60 raises the truck about 2",being the 350 takes 4" blocks in the rear, compaired to a 2" block in the 250s with the TTB.

 

From what I've heard (which might be wrong) the larger blocks in the F350 are only larger so the truck squats less with the larger payload. 2wd F350 and F250 have the same front suspension, the only difference is the lift blocks in the rear. Rear springs are possibly the same. Can't remember if I actually measured it or not, but I'd think the D50 TTB axle housing would be thicker at the spring mount than a D60 straight axle. Thicker being the TTB would actually be lifted more with the same springs. But maybe its just the way it looks squared off. I should go out and measure, but its damn cold out right now.
Once again, thats only what I've read on here and other places online, I might be incorrect in that assumption.

No lift is needed to clear the oil pan. If anything, the crossmember would be in the way, not the oil pan. F350 front springs are arced differently in the front and have a slight smile to them while F250 springs tend to be flat or slightly frowning. I believe the difference has to do with the way each end of a TTB allows more twist on the springs than a solid axle does. Again thats just what I've read online...

As far as the ride goes, I really don't know. I rolled my own reverse shackle kit when I put in my D60. Unfortunately, I used gasser F250 springs off a worn out plow truck. They ride like **** and are frowning. I have a set of newer (2000ish?) Superduty springs that supposedly ride real nice, except they're 4 inches longer in the front so I have to redo all the front mounts before I can put them in. Don't know when I'll have the time

I just used the stock F250 2wd pitman arm and it seems to be working ok. However, when I was replacing the steering pump and greasing stuff last week, it seemed like the steering box ran out before the axle hit the stops. Looks like the pitman arm on the F350 I just picked up is an inch longer, I'm going to swap it over when I get a chance and see what happens. I'm not convinced a drop arm is needed. BTW, the front of my truck went up almost 5 inches when I put the D60 in, thats coming from a coil spring 2wd suspension though. Didn't at all look like I needed a drop pitman arm so I never bothered.

Also when I put mine in, I used stock rear shackles. They fit just fine, and are cheap. But the way they're setup is upside down from the rear, so I think the bushing is squished all wrong and at the least the passenger side seems to be bottomed out
