Rancho 9000's might have been an oops
I installed Rancho 9000's on our Dodge 3500 about 12,000 miles ago. 4000 miles hauling our single slide 9ft camper / towing, 3000 other miles towing cargo/flatbeds, and about 800 miles towing our Car...

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.
