5.7L Hemi V8 Passenger-Side Rebuilt Cylinder Head

The Mopar 53021616DG cylinder head is a professional-grade, remanufactured replacement component engineered for 5.7L Hemi engines produced from 2016 and up. This passenger-side assembly is thoroughly disassembled and hot-tank cleaned before being pressure-tested to confirm casting integrity. Each head receives a precise valve job with all required angles and vacuum-tested seals to restore factory-spec compression. Technical precision is maintained throughout the remanufacturing process, which meets AERA specifications. The head features new valve guides and valve stem seals, along with new valve seats installed where necessary. The mating surface is either PCD milled for aluminum components or CBN milled for cast-iron to ensure a perfectly smooth finish for reliable gasket sealing. Compatibility is determined by casting number; buyers must confirm that their existing head matches casting # 53021616DG before purchase, as improper part selection voids the warranty. This head is designed for various 5.7L applications, including Dodge Charger, Challenger, Durango, and Ram 1500/2500/3500 models from 2016 onward. It is critical to verify specific engine VIN and casting details to ensure correct fitment, as incorrect part installation is not covered under the included 90-day, unlimited-mileage warranty.
