    If you're talking about the MDS (multi-displacement system) I think they do. However, I don't think the 5.7L is available in 2500/3500 anymore.

    Kinda forgot about that, that sure wouldn't help the crappy gear ratio in mine.

    Not sure, ours will pull great, just doesn't have the low end torque I am used to. And when towing or if the plows are on, it is constantly hunting gears. Could be crappy gear ratio or because it's operating as a V6 or both.

    I am in the market for another truck, actually looked at a few that had 6.4s and ended up not even considering them.

    I said pulling, not towing.
    Noticed the difference when we had to move a dumpster, twice. Once i pulled it with the chebbie. A different time, he did with his ram. The ram didn't seem to have the torque it took to get it to move at low rpms. I would have expected more from the Cummins.

    When he moved it with the Cummins, i said how gutless it seemed. There happened to be a concrete truck driver there who said he's got a chebbie and a Cummins. He said the Cummins is a dog when stock. Not sure what modifications he was referring to.

    How does it compare?

    I have 2 6.4 trucks, both with 4.10 rears. Go that route. One runs a 2.5 yard salter plus a 8.5' HD2 with 6 speed auto. Other a 9.5' XV2 plus blower and usually 500 LBS of bag salt and 8 speed auto. Both pull great. I do notice with the 2019 [8 speed] it does hunt a bit with the mds when driving light. That hasn't happened with it loaded up. Love the hemi's.

    6.7 cummins is no 5.9 HO but at least I have the warranty-got the 4.10's in that too. No point in going with the 3.73's.
