Mishimoto Performance Aluminum Radiator for 2019-2026 Chevrolet Silverado / GMC Sierra 1500 (MMRAD-T1-19)

Fits 2019-2026 Chevrolet Silverado 1500 and GMC Sierra 1500 models, including Trail Boss, Denali, AT4, and ZR2 trims.

Built to handle the demands of heavy towing and off-road use, the Mishimoto Performance Aluminum Radiator replaces the failure-prone factory unit and its brittle plastic end tanks. This radiator features full TIG-welded aluminum construction with durable aluminum side brackets to eliminate the risk of leaks and cracks caused by heat cycling and chassis flex. The core provides a massive 119% increase in volume and a 31% increase in coolant capacity over the stock radiator, ensuring stable operating temperatures under heavy loads.

To support heavy-duty performance, Mishimoto engineered this radiator with strutted tubes along the top and bottom rows for superior structural rigidity. It also features an upgraded 7-row internal oil cooler, improving heat transfer efficiency compared to the standard 6-row OEM design. Each unit includes a magnetic drain plug to trap metallic debris and pre-applied foam for a complete fan shroud seal.
