OE (Original Equipment) plastic tank radiators typically fail at the joint between the plastic tank and the “crimped” aluminum header/core. PDI’s Big Boss Radiators eliminate this failure mode by replacing the plastic tanks and aluminum core with either Bolt-On (steel) or Solder-On (brass) reinforced tanks and copper/brass core.

PDI’s radiator tanks and structure are made of high strength, heavy-gauge rust resistant steel or brass.

Our radiators are professionally engineered using the latest Solid Modeling CAD (Computer Aided Design) and FEA (Finite Element Analysis) software.

Design made for heavy hauling or big horsepower applications.

100% leak tested under water before leaving the factory

Wind tunnel tested to meet or exceed OE heat transfer performance.
