Use your axle softness parameters (defaulted on all trucks)
You can also do the load on the front axle yourself by finding your truck, be it a mod or a def.track. I think everyone knows where and how to look.
If a very soft cabin seems to you, then with this line cabin_suspension_travel (in the main textbook of physics) you can correct it yourself.
For version 1.40
