I've not checked my tool pouch under the passenger seat but I do have two sets of different sizes from other vehicles with adjustable preload. I'm not sure if they will work but I will check this weekend!
I used a brass punch to knock the lock ring loose, then jacked it up and they move by hand, dont need any other tools than that to adjust. So far I've went one full turn up front and 1 clicker harder on Compression and rebound, seems to ride a bit higher in the front which I noticed it sagged a bit after I got it broke in.
I did go up 1 click in the high speed compression for both front shocks. After the adjustment, no more of that feeling of a jolt. The trails have these big humps and on the other side they get eaten out by people gassing it while going over and digging in on the other side. That makes for some pretty hard hits on the front suspension when you land in those dugouts. So glad it's adjustable
