OK...I have an '05 F-350 PSD 4WD Crew Cab Long Bed w/FX4 (w/Rancho "branded" shocks) and Camper Pkg.

Not only a major stiff ride unloaded (I expected that), but it sort of loses its directional stability when it hits a pothole, etc., (I don't expect that). Overall, don't like the ride very much. I know it's a truck and it does its trucking job very well, but I'm shooting for a smoother, more controllable ride in between its jobs.

So, it looks like replacement time. I'm seeing availabilities with Bilstein which are sounding like they're stiffer yet and Edelbrock IAS. I've had very good luck with Bilsteins on other vehicles which needed stiffer rides. I'll never buy the Edelbrock's again...blew both the rears on a 4WD Durango in less than 10K miles for no apparent reason. Edelbrock offered replacements but, they weren't worth the slightest sweat to put them on. I consider them junk. I replaced them with Bilsteins and never looked back.

I think the "real" Rancho RS9000 adjustables are the way to go but...after looking at their online catalog, they don't have a listing for my application. The closest they come is the RS99042/RS99047 combo for 0" lift. It could be that the Camper Pkg is considered a lift. The listing for the combo above says:

2005 4WD F-350 SuperDuty (1 Ton) w/ Single Rear Wheels except Chassis Cab

What's a Chassis Cab...are they talking about Crew Cab? BTW, they look like they have another combo, but it states that it's applicable to trucks with a Rancho Leveling System. What's that?

Bottom line: Has anyone out there in SuperDuty land put the RS9000 on a package like mine? If so, what the heck are the model numbers?

TIA

journeydog,

Yes others on this board have installed RS9000, i don't remember the model numbers but they should be along shortly.

No the camper package is not considered a lift, it just increases the spring rate, adds overload springs if they weren't already in the build, adds rear sway bar and the loading sheet.

You need the shocks for a 0 lift application, i believe the numbers you found on the Rancho application sheet are what you need.

A chassis cab is a truck that comes from the factory with no bed, usually is always a dually and is designed to go from the factory to an upfitter who finishes the final build by adding some kind of work body (ie, cargo box, flat bed, ambulance package etc).

Hope this helps

 

Good info...thanks!

I should have thought more about the "chassis cab" definition. I have a motorhome and that's essentially what they build most of them on.

All I need now is a verification that my numbers have been proven and I'm ready to go.

I just put the 9000s on our truck (love 'em) and it is the same as yours other than it's a Supercab (yes we have the camper pkg too), so it should be the same shocks for you. Mine are numbered: RS99042 and RS99254 and they fit perfectly.

Found mine brand new from a dealer on eBay for $300 delivered and no tax.

Good luck!

 

I have an '01, but the RS9000x's are definitely a 1000% improvement over the stock shocks.

The "branded" Ranchos from the FX4 package don't seem to be anything special. Maybe white paint?

 

Thanks for the good replies! I think I'm going to end up doing what one of the guys did in a much earlier thread...use the stiffer Bilsteins in the front and RS9000s in the rear. His rationale was that the loading on the front end isn't going to vary, while its desireable to have the adjustable option in the rear for different loads. Sounds like good advice.

BTW, the Rancho rear shock for this application is now listed as the RS99047 - a new addition to their catalog. They're still not available at a lot of the locations I checked, but they can be had at a few. Until recently, Rancho had no direct catalog fit for a SRW, so folks were advising installation of the RS99254, which is now listed under the dually application.

Since "diesel_dan" is using the 99254 in a camper application, maybe that's the way to go. I'm planning on eventually using my F350 for a camper load also. Wish I knew the spec difference between a 99047 and a 99254, but maybe its insignificant. Same price, probably pretty much same everything else. At least they're real and not just white paint.

BTW...how do I get my signature thingy working again? Used to be OK, but now the option to turn it on/off is long gone.

 

The F350 DRW has 2-inch blocks under the rear springs and the F350 SRW has 4-inch blocks so probably the only difference is a little bit of length.

Signature works if you have paid to be a "supporter" or if you have enough "reputation" points.

 

I've often changed the settings on my FRONT rs9000x's....

Highway driving, off-road, or just toolin' around the countryside, I adjust them for each.
