Shock Valving

I'm moving forward with a long-arm upgrade with 3-link rear through RK, also going with a front coilover conversion. "Off the shelf" valving for all of their shocks is a 60/40, which I don't think is what I'm really going to want for rock crawling. I know ideally I'm going to want a firmer rebound than compression, but I'm a bit up in the air about what to run. While just about all of my offroad activities are rock crawling, it's no trailer queen. I drive it to the trail, and quite a bit in DD situations, so I need to find a happy medium between the two.

Front coilovers are 2 5/8" with remote reservoir, I am considering a 40/60 valve job there. Thoughts?

Rear shocks are a 2" with remote reservoir, due to the smaller diameter I'm thinking of going a bit stiffer, say 50/70 there. Again, thoughts?

Would you think going further apart on compression/rebound might not be best for the DD situations? Example: a 40/70 for the coilovers and 50/80 for the rear shocks.

Rig weighs in at a bit over 5,000 pounds when full of trail gear.

Why not contact the company that builds the shocks to see what they say?

Jeebus. Maybe some of the coil spring dudes might be able to chime in. I think I changed to my Heckethorns about 12 years ago and they've worked well everywhere.

I wouldn't worry too much about the "rock crawling" around our neck of the woods as it is typically much faster due to being slippery than, say out in Moab.

I would call Rock Krawler and get their opinion with the setup you have.

Agreed the skinny pedal definitely is in play a lot here with the slick rock, still fairly certain I'll be wanting a stiffer rebound than compression, yes? Still waiting to hear back from RK, their shock guy was out at EJS and then down at Jeep Beach so apparently has a lot of catching up to do.

Wondering if a stiffer overall configuration is not a bad way to go considering we're pretty quick over the rocks.
40 being "Light-Medium" 60 being "Medium-Firm" 80 being "Extra-Firm"
Maybe being a little closer to balanced on compression/rebound wouldn't be a bad idea, say a 50/60 on the larger coilover and 60/70 for the rear shocks.

Yeah so it looks like there was a typo on their website, the 60/40 that was listed as their stock valving is supposed to read 40/60, and this will be the ideal setup for me unless I want to firm up to 50/70. Thinking I'll go ahead with the 40/60 for starters, a revalve job is pretty cheap, if I feel like I'm hammering on it too hard I can always bump to the 50/70 configuration.

I don't think you're going to even notice the difference between a 40/60 or a 60/40. It simply won't matter on the trails you're going to run here, especially if you plan to roll on 40's.
