Nerd’s Eye View: SEMA Edition 2012, Part II


Maybe it’s used to supply pressure to what looks like an actuator… (edit: nevermind, that looks like a small electric motor on the actuator, so….. what on the truck uses pressurized air?) 


Which allows the light bar to be angled up and down.



Everything on this truck is super strong.  Just check out the size of the trailing arms.  The wire diameter of the springs is pretty thick too.  I think that’s a rear sway bar attached at the end of the trailing arm.


The upper spring and damper mount look like they would be strong enough to support a building.  I imagine the cylinders are welded into the box sections to add stiffness while maintaining a relatively lightweight structure.
