High Performance Cooling

Looking for a lightweight aluminum radiator without the hassle of making brackets to fit your application? Griffin PerformanceFit radiators may just be the item for you! Featuring an exclusive MegaCool core that features oversized 1.25 inch wide tubes that offer an astounding 25 percent increase in cooling power. The added tube size is capable of cooling moderate to heavily modified engines. Griffin also offers an option for LS swap vehicles that will make an LS transplant even easier. Carefully designed to work with various makes and models, in some cases the factory fan shroud will need modifications for correct fitment. Available as a ComboUnit package which includes a factory mounted high performance electric fan with a custom fit aluminum shroud.

Strength and Reliability

The key to strength, durability, and performance comes from vacuum brazing. Vacuum brazing is a manufacturing process used to join all the components once assembled that requires the use of magnesium. Magnesium is found in aluminum alloys to give structural components strength when high strength is required. Griffin Thermal Products utilizes this process to offer one of the toughest aluminum radiators on the market today. By producing the tubes, fins, headers, side bands, tanks, and mounting brackets in house, every piece is performance matched for optimum cooling with unsurpassed quality.
