OME 885s & Bilstein 5100s

[HokieRunner]

885s should be enough unless the OP is adding a lot of weight (bumpers winch etc).

Some folks who have installed the 886 with little to no added weight have found the ride to be harsh.

0 - .85 - 1.75 - 2.5

They don't get stiffer as you raise the height. That's actually a myth for a few reasons

How do you figure? when you preload the coil spring .85, 1.75, or 2.5 inches that will force the spring to always be more compressed than normal, giving you a stiffer ride. Take this guy for instance, high preload = no spring travel = stiff ride

I'm looking at running 285/70/17 duratracs seems it might be a little tight at that setting?

Might have to set it at .85

check my build thread. might answer some of your questions

thats the tire size I'm running.

From what I understand after reading the whole thread the OP was wrong. Most users who replied agreed that increasing the preload will in fact make your ride stiffer. I had to compress my 885s and barely could pry them in place, I can't imagine trying to install them with 2.5 inches more length. Let alone ride quality when the spring is already compressed that much. [MENTION=94545]MTD[/MENTION] said it pretty well here:

Actually perch height does matter. If you are loading the spring then you are increasing the amount of force required to further deform the spring. So say you preload the spring by 2 units then you just increased the amount of force needed to deform the spring by 2 times. Just graph it you can see it then. It has nothing to do with the dampening mechanism of the 5100. In a sense you just increased the activation energy required to compress the spring.
