Rancho 9000's might have been an oops

Thanks for the followup ticki2, and sorry I didn't respond sooner. Good to hear the Bilsteins are working for you!

On the 2500HD I replaced the OEM shocks at 17k , the back end unloaded was bouncing around like a yoyo , the Bilstein's cured it without being harsh . They seem to work equally well both loaded and unloaded . There are several GM forum sites that I've read where folks were giving away OEM shocks if that tells you anything .

I am running Bilstien 4600 series ( yellow and blue)on both my 2500 and 3500 GM's . The 3500 DRW gets to carry the camper . Very satisfied with both , whether loaded or not . If you have always used OEM I think you will see a big improvement with Bilstien , Rancho 9000 , or KYB ( especially during frost heave season ) .

Thought I would drag up this old Rancho thread instead of starting new...and yes I have "searched" also but could not find much on this specific question;

Will upgrade shocks soon, I know a lot of Folks like the R9000's as they are adjustable.
Problem is...here in New England...anything you our under your truck will be rusted over real soon.
So what would be the point in adjustable shocks if you can no longer adjust them?
Or is this a non-issue (are the adjusters made of non-rusting pixie dust?)

What would be a good alternative in a fixed (non-adjustable) shock and why?
R5000's?
KYB's?
Other brands?

Bill,
Our Minnesota roads are unfortunately heavily salted as well. In June 2006 I purchased front and rear Rancho 9000 shocks from Sams off road May of 2008 I noticed I could no longer adjust the rear shocks. I contacted Sam's off road and they sent me Rancho 9000XLs to replace the failed 9000s. The 9000XL model replaced the 9000 model and are a larger and seemingly better built shock. Today I am still running the original 9000s up front and the 9000XLs in the rear.

Increasing the shock damping up front will reduce fore to aft porpoising even if the front loses some weight.

yes...I got to thinking about this yesterday after I posted the question of why put the R9000 on front (versus the non-adjusting R5000)...I think this makes sense. Firm up all 4 corners.

Looks like R9000 will be on our to-do list.

Thanks all, Bill

Yes, to get full benefit, they need to be on all 4 corners. When the truck rocks from side to side, both the front and rear rock. Having stiffer dampening on both ends both contribute to controlling the side to side rocking.

I will say that the 9000's help is much more noticeable on SRW trucks than DRW truck. I assume that is mainly due to most SRW trucks being over their GVWR and most DRW trucks being significantly under. My testing was with the same camper on both the SRW and DRW.

I had to replace our Rancho 9000s under warranty-they were a little over 12 years old. I cant complain. Keep those receipts. Yes lower bushings on the Fords due to the U shaped mounts wont allow to snug the poly bushing, so it (too)freely moves and wallows out. But I get about 5 years on a set of bushings. Shocks should be able to pivot but not slide in mount-

While the weight doesn't change that much if I dont turn up the front shocks its noticeable as far as handling?

I love mine, hope they don't die on me but if they do I recently got them at my local 4-Wheel-Wrong-Parts, so I should be fine.
