I thought you already had that worked out otherwise...

 

Nope. Plan changed up a bit.

 

Well then, keep me in mind!

 

You know it!!

 

Bilstein makes a lot of different shocks... What is the part number?

From my RSK install I learned that this is the front Bilstein shock most people install:

The Bilstein part number for the front is:
33-185552
with expanded/compressed dimensions of
25.93"/15.91"
255/70 compression/expansion valving

Was told that the dampening number is means 2,550/700 newtons of force.

I wanted shocks with more rebound (expansion) dampening and am now using these:

Front shocks, Bilstein part number: 33-230344
15.91"/25.93" compressed/extended lengths
360/80 compression/expansion valving

 

Lolman I feel missed.... been working alot on a road job running a d8n. ... so not a lot of free time.... and to top it off girl friend has been looking at rings....:-( and a new house on a good note I did find two boxs of ps obs parts in the garage yesterday I got like 2 years ago....lol

 

I did the RSK a few years back when I switched from 2x4 to 4x4. No issues with clearing the IC. Can't really compare ride as I had coils in the front before. Rides like a brick now, but I've got old OBS springs. Need to get some SD springs and better shocks.

 

How do you like the new shocks? Compared to the old ones???

 

'Old ones' as in the factory ones or 'old ones' as in the first set of new Bilsteins?

The factory shocks had 160k miles on them. But, they were controlling front and rear leaf springs that were factory, stiff as an I-beam. So, overall the ride sucked.

The rear B codes and front U codes with the first set of Bilsteins was waterbed cushy.

In fairness I did not get the sway bars (dinked around with rear only, both, and rear) until after I got the newer stiffer shocks. Body sway is an issue as I (and the family) drive %99 on the street.


The new springs, added height and short wheelbase (of the F250) caused a kick up in the rear after the rear shocks compressed, and then extended. I'd hit a bump, and after them bump, the rear would kick up as the shock did not proved enough expansion or rebound resistance. I wanted a bigger second number and found catalog part numbers that met my needed compressed/extended dimensions. The second pair of Bilsteins stopped the kick, but are now a little too stiff on compression.

If I had all of my Bilstein money back, I could have bought custom valved shocks that had the compression of the first set, and the rebound of the second.

Not sure if I answered your question though?

 

I need shocks really bad and all this talk about valving has me thinking I should get a set of Rancho 9000s with the adjustable valving.

 

I was thinking as compared to the first set of bilstiens. You answered just fine. Thanks

 

I have these on the front 5125 series. F4-BE5-6248-H5 They are fine just driving but towing they suck and allow the front to bounce too much.

 

I found a 6249?

The F4-BE5-6249-H5 has 255/70 valving which is the same as my first set. Yes, with them the front moves a lot just daily driving, I can imagine with a trailer... I may go back with them though to see how they mix with the stiffer rears.

 

I was reading elsewhere that the pmf will not fit with a 6.0 ic..

I can't imagine that being the case.

Has anyone had any issue with that? I mounted mine with my sky installed long ago but the sky was bought with the ic option as I knew at some point it would get one.
