Question Best way to tune adjustable shocks?

So after a lot of messing around, i finally have my new Fox 2.5" DSC's installed and on the rig. I now need to start the process of tuning (i.e. adjustment via clickers) them to where i want them.

As i have no idea what Fox ships them as, nor is there a way to tell this as far as i can tell, wondering how others would suggest that i start on this. For those not familiar with the DSC system, per the website - here is what i have to work with:

"two adjuster knobs allows 10 separate low-speed and 12 high-speed compression levels"

For those who haven't been following my build and starting new on this, my original problem statement which has been evolving over time is that i was getting what i thought was the shocks blowing through the stroke and bottoming out when i was hitting bumps / air at speed (20ish MPH).

What we learned through a lot of trial and error is that this was only part of the problem, and I've had to do body trimming to get rid of the body tub smacking the tires as well. There is also is some thought that the bump stops are not set up correctly, but i wanted to get shocks installed and body done before i go down that road.

All details are located in build string, with cross reference to individual posts on each item in detail.

TIA for any / inputs as usual

This is totally going to be trial and error on your part. Low speed and high speed adjustment are in relation to how fast the shock moves. If it where me I would start on good roads. Set both high speed and low speed to 0 then dial in your you low speed adjustment till you get the firmness you like in the ride. Dialing in the high speed adjustment is a lot harder. Do you set it for the average or the extreme. If you set it for the extreme then you will be to stiff most of the time and control can become an issue. Also remember that front and rear shocks will probably be adjusted slightly different. Keep records of where you are in your adjustments.

FYI I have not experience setting up this shock or and shock on a Jeep. But I have set them up on my dirt bikes and Corvette. There is no doubt someone may have setting that you like but what I found is was better to start from scratch and find what I liked.

Thanks for jumping in Terry.

The points you are making around what set for are interesting. I also have done this previously on ATV, UTV, and MC - but never on a Jeep. The hard part for me to wrap my head around is the street vs. dirt issue. I've never had that dynamic on any of the previous platforms, which is a new and relevant wrinkle as the rig stays on the road 90% of the time.

My thought process there is that HS will end up being stiffer than LS, and the rear will be stiffer than front (this is where i ended up on UTV, which is similar to the JK).

I did also keep a notebook on my settings for UTV and documented where i ended up, so sounds like that method is directionally correct here as well

Thnx!
