Is the exhaust brake standard?

[telliott]

In the process of ordering a 2018 crew, Lb, SRW, Aisin. Can't seem to find the exhaust brake listed anywhere as an option or as standard. Anyone have insight? What about cruise control?

[Newsa]

Both standard with all transmission's

Good on the 3500/AISIN, now get the factory rear air ride.
