Dodge upgraded the 2003-2004 model year Cummins and covered up its major flaws. The truck became a reliable platform that's easy to modify. The fuel system benefited from the Bosh CP3 injection pump that's still often utilized today. HeavyWeight Diesel advises upgrading the air intake system with parts from AEM, aFe, or S&B, as well as the exhaust system with parts from Diamond Eye, Magnaflow, or MBRP. We also stock suspension parts and lift kits that would make your truck feel much more pleasant to drive. To top it all off, reprogramming the system with a tuner from Smarty, Edge, or EZ Lynk would make your truck an optimal, efficient powerhouse.
