  • 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.
