You can try increasing the suspension travel, or adding a negative yOffset to the two front wheel nodes. Or you can increase the rotation of the axle animation, but that will squish the front lift bags and plates, and they won't look right...
I would like to, but it's quite a bit of work to switch to the new material method, and there are a LOT of parts on that truck that would need it. I'm not sure I have the time or energy for it. Also the script I used/need for all the extra design configs hasn't been converted to FS25 afaik.
