Dual pass radiator designs force coolant to travel across the core twice before exiting, significantly increasing heat transfer efficiency under sustained load. The soldered core construction enhances thermal conductivity, while TIG welded aluminum tanks provide the structural integrity required for aggressive off-road environments.
The clamp-style shroud mounting system avoids traditional through-core mounting methods that can lead to failure in harsh vibration conditions. Combined with over 3700 CFM of SPAL airflow, this radiator combo unit is built to support high horsepower LS and LT-powered off-road builds. If your rig demands serious cooling capacity and reliability, this 31 dual pass combo unit delivers.
