Mishimoto 67-72 GM C/K Truck X-Line Performance Aluminum Radiator

Upgrade your classic 1967-1972 Chevrolet and GMC C/K trucks, Blazers, and Suburbans with the Mishimoto X-Line Performance Aluminum Radiator. This direct-fit replacement features a high-efficiency 2-row core that handles increased heat from performance engines and transmissions like 4.1L, 4.8L, 5.0L, and 5.7L with 435GA, Powerglide, SM465, THM350, and THM400. Engineered for daily drivers and track use, it delivers reliable temperature control in demanding conditions.

Key Features

  • 1.5" Inlet/Outlet: Matches OEM hose routing for plug-and-play installation on manual and automatic transmissions.
  • Polished Finish: Mirror-polished tanks add underhood style while resisting corrosion for long-term durability.
