Collection: 2019-2021 Cummins 6.7L

Navigate the high-pressure era of advanced CGI block design and sophisticated electronic integration. The 2019–2021 24-Valve Cummins brought massive structural revisions to the Ram heavy-duty lineup, transitioning to a high-strength Compacted Graphite Iron (CGI) engine block, moving to a maintenance-free hydraulic lifter system, and introducing a revised Bosch common-rail system running higher injection pressures. Paired with updated ECM strategies and refined emissions system mapping, this generation is a premier choice for extreme towing demand, fleet work, and high-efficiency performance calibrations.

Whether you are performing routine maintenance to safeguard your high-pressure common-rail components, optimizing airflow to drop EGTs, or upgrading your chassis for better towing manners, find everything you need here.
