Heavy Hauler Long Block Engine Dodge Ram 6.7L Cummins 2019-2020 BD Diesel

Built for towing and work

The Heavy Hauler is D&J Precision Machine's long block for 6.7L Cummins trucks that tow and work hard. BD rates it for up to 700 hp.

It pairs a D&J Stage 1 cylinder head with a street/towing camshaft that BD says lowers EGTs, plus custom ARP 9/16 head studs for head-to-block sealing under load.

On these later engines D&J goes back to the 2018-and-older valvetrain: solid flat tappets and adjustable rockers in place of the factory hydraulic roller lifters, for reliability.

Who it's for

Owners of 2019-2020 Ram 2500/3500 trucks replacing a tired or damaged engine who tow heavy or plan moderate power upgrades.
