    Default Chrysler MDS (AFM)

    Chrysler calls it multi-displacement system. It’s like GM’s AFM where it drops from V8 to V4

    2013 Ram 1500 5.7

    Lifter collapsed, didn’t pump up and took the cam out. The ridge on cam was cut down so much that it was sharp as a razor.

    So just like GM, I can disable the MDS for 200.00

    This is no range device in the obd connector that stops the v8 light from flipping to v4. I go into the ECM and flash it with no foot print.

    We have not had near the failures on Chrysler like we have GM.... but the MDS lifters and cam is about 4200.00 because of the parts cost is double what GM kits are. The LS stuff is so popular the cost has come down due to sheer competition.

    Food for thought....

    The Ford 6.4’s have put a fair amount of groceries on the table. Love these front cover jobs. Ignore that coolant additive warning and you’ll be replacing the front timing cover before you know it.

    Is the 5.0 the most reliable out?

    Hands down for Ford, especially with the 6 speed behind it.

    My opinion on Ford overall yes

    Far as manufactures go that would be tough and matter of opinion. I said I’d never buy a Toyota, but all we do is maintenance on the Tundras. Some 5.7’s the cam towers leak oil but they don’t have turbo’s with direct injection or AFM/MDS issues.
