According to the RAM Chief Engineer, it is.
It's also used in the 4500 and 5500 Chassis and cab models with the 6.4 engine.

I stand corrected
Thanks for the link. I'm going to check it out now.
When my dad bought his 2014 ram/Hemi I distinctly recall the salesman saying that MDS was only available on the 1500 series.
To be honest I think mds makes the engine most appealing.
My charger for example is an 06 and has mds. With low winds,cruise set at 60 and no traffic to brake for I can get 30mpg with premium
I have a diablosport running the 91 octane tune. I don't think the tune did much for top end hp however throttle response is so much better. Even light throttle inputs translate to significant speed increases.
I tried the mpg booster tune for 1000 miles and honestly the mileage decreased vs stock tuning.
The high octane tune netted the best mpg on the highway however I feel that city mileage got worse,not that it bothers me since the increased responsiveness more than makes up for it in smiles per gallon.
Anyway mds makes my car a gas miser while highway cruising yet downshift a couple gears and smash the gas and immediately realize 400 tq sounds amazing.
I'm a mustang guy. I truly love them however I find myself looking at challengers now instead of my beloved mustangs.
And I feel every engine make should incorporate some form of cylinder deactivation. To me it's a no brainer. Immediate power when you want it and incredible fuel efficiency when you don't.
When I think about just how much power these hemi engines are capable of,yet will sip fuel until that power is commanded for.
Fantastic feat of engineering.
And I've seen YouTube vids of hemi teardowns for various upgrades and there is no wear anomalies when the cylinders are measured for taper etc.
You'd think because these engines spend a significant portion of their lives only firing on 4 cylinders that those 4 cylinders will have more wear however that doesn't seem to be the case.
Sorry mustang. I love you but until ford can engineer cylinder deactivation into their engines I'm gonna be dodge friendly.
