Still no reply to my email as well - I've not had a chance to call them today but will follow up with them tomorrow if I don't hear from them.

 

Well, I got tired of waiting for a reply to my e-mail to Rancho Tech Support, so I called them.

They also confirmed over the phone that the correct P/N for my 05 Ex, 4x4 with factory stabilizer brackets is 5410.

Guess that's what I'll tell Summit to send me. I'll update once received and installed.

 

Glad I saw this post.

I had looked the other day on Oreilly's website to try and find a replacement steering stabilizer and was specifically looking for a rancho version without luck. Apparently if you enter 7.3L diesel that part number won't show up because it only lists it for the gas engines?

Oh well now I know what to get

 

Got the new Rancho stabilizer, PN 5410. Definitely the right application.

Now for the review:

I've been driving the truck for over a week now with NO stabilizer, and didn't really feel any major problems. I assumed that was because the old stabilizer seals were bad, so the damping was reduced. Truck handles pretty good, maybe just a little more play in the steering than I liked, but I haven't had a chance to do the adjustment to the gearbox yet (and I wanted to see what the new stabilizer would do).

So, after driving to work and back today (40 miles round trip, combination of highway--severely rutted--and in town driving--complete with potholes and sunken manhole covers) the verdict is: Save your $50. I don't notice any substantial difference between this nice, aftermarket stabilizer with much more damping to it than my stock takeoff, and no stabilizer at all.

I'm driving a stock height truck, with stock size rubber, and good suspension components. A lifted truck with bigger rubber might have more of a need, but IMHO, trucks like mine should be just fine without a stabilizer at all.

My $.02, but if I had it to do over again, I'd keep the $50 and use it for sexy V10 badges to make my truck look tougher.

 

Here is another one for you folks on this matter. Rancho list the 5413 for 2004-2005.

No way. Nada. Not a chance. It has no eyelets on the end, just threaded studs. Use the 5410 for ALL YEARS!!

 

So on a stock Excursion is there ANY advantage to going to a dual steering stabilizer over a single?

In my mind, as is, these are big heavy vehicles with good sized tires - and renowned wandering problems - so could more be better?

Note: I actually bought the dual unit months back since it wasn't all that much more money, but it's still sitting in the box as it turned out to be more than a simple bolt on task.

 

As I stated above, on my stock truck, I noticed very little, if any difference between my single Rancho and NO stabilizer; I certainly wouldn't spend money on a double. I would tend to believe that if you have problems with slop in your steering, the way to take it out is to make sure your linkage is good (ie, good ball joints, tie rod ends, etc), and your gearbox is good.

IMHO, using steering stabilizers to try to take out wander is merely masking the real problem. I see the stabilizer as a way to reduce some of the force applied to the steering by big tires, not to remove slop in the steering.
