Bilstein 7100 Valving

I'm going to buy some Bilstein 7100s and I want to know the correct valving people are running. Bilstein says to run 400/100 all around but some people on the board run 360/80s.

My set up: 3 inch RTE lift, RW bumper, winch, 3-link some of those awesome storage boxes that Troy makes in the back and a rear bench seat. Plus I will be getting a roof rack in the future. I do about 50% on road, 50% off road. I want a smooth ride when I'm on the road more, than a stiffer ride off road. Will 360/80 valving be the best bet? Or should I step it up to the 400/100? If I get the 360/80s and they are too soft is it easy to just revalve them to 400/100?

I know Bowtracer is running 400/100s but he has a D110. Anyone running 400/100 or 360/80 on their D90 and can tell me how the ride is? Thanks!

I'm running 360/80 with 3in RTE springs and 12'in SB's in the front and 14SB's in the rear with almost identical suspension setup you yours with minor tweaks. The truck drives great, if anything i wish it was a little softer with the RTE springs. You might check which springs you have from RTE being that they have stiffer springs for Hard tops on d-90's.

I have a POE top. So hard in the winter, soft in the summer. I called Steve at Rovertym and he said to go with the 275/78 valved shocks. I told him some guys run the 360/80 and he said since the Rovertym spring is a bit stiffer then i should go with the 275/78 valved shocks. Thanks for the input Anthony.

Anyone else have experience with these shocks?

I have that setup almost exactly. I run RTE 2 inch on my hardtop 90. 360/80 in the front (10 inch) and 400/100 in the rear (12 inch). I used to have 275/78 in the front and 360/80 in the back but it was too soft in my opinion. After I revalved them stiffer, the ride on the road improved. I have no sway bars and the stiffer settings provided more stability. If I recall the RTE springs are pretty stiff and when I first put them in and drove around on the trail i remember wishing I had more rebound dampening in the rear. I also remember on the softer setting bottoming out with a heavy load on sandy washes if there was a dip. My truck drives great now. I say go with the 400/100 in the back for sure. If you really think they are stiff then revalving them is a 20 minute job. Let me know if u have more questions.

Thanks Steve. I think im going to try 360/80s all around because my POE top is about 50 pounds heavier than the soft top and roll bar on i imagine. its quite light compared to an actual SW top. if the valving is too soft or too hard I can always change it.

That's true. Revalving is pretty simple but it's a real pain in the ass. I hear if you have the special Bilstien tool it's easier but I've never used it. A recomendation.. if you're doing a lot of off-roading with the car and traveling a lot of fire roads I recommend placing a spot of glue along the seam of where the gold dust shield meets the shock body. Fire roads rattled my dust shields loose in the front. Doesn't matter for the operation of the shock but rattles like hell on the road. Didn't happen in the rear only the front.
