I've got the KYB Monomaxs on all four corners and it drives noticeably different than the previous Rancho 9000XL's. --The Ranchos had a total of 30,000 miles on them when they came off the truck and all 4 were set to position 9 and came off in good shape.
My perception is the ride with the Monomax is stiffer (in a good way) and more controlled than the Ranchos 9000XL's. Whether they stay this way remains to be seen (In my large amount of research on the Monomax, found a few comments of them being too stiff initially and then getting better). The only additional comment (speculation) I can provide is that possibly if you're not constantly carrying the 5000lb+ load in the bed that I am, maybe the Monomax's would be too stiff. ??
Due to time and other issues (wrenching burnout) I did not put the Bilstein 4600's on the front and then try to compare them to the Monomaxes. I can say from examining the two (Bilstein 4600 and KYB Monomax) side by side, the Bilsteins seemed to have a better fit/finish to them.
So, someone else I guess needs to compare the KYB Monomax to the Bilstein 4600. Any takers?
And FWIW, also let me add I'm extremely suspicious of anecdotal, testimonial type, one data point opinions --like the one I'm providing here. As humans, we make terrible data taking devices and are better served by testing in controlled conditions with a large set of data points; without that, almost anything can be claimed via testimony.
Yes, I see your point. What we really need is a large number of testers who will volunteer to compare the KYB Monomax to the Bilstein 4600.
If there are any volunteers who are willing to take part in this project, please identify yourselves.
