High Efficiency Core
The SPELAB Cool Radiator is built with a high-efficiency core that has more fins per inch, and heavy-duty tubes to maximize cooling potential.
Internal Reinforcements
Manufactured using special aluminum brazing techniques, the SPELAB Cool Radiator Features internally reinforced end tubes that have additional strength at the outside corners where the core is most vulnerable.
Gasket Design
Using a proprietary rubber gasket to allow for expansion, contraction, and flex is one more reason the SPELAB Cool Radiators are built to last. The gasket is a common failure point in many OE radiator designs.
Revised End Tanks
For added strength and durability the SPELAB Cool Radiators feature revised end tanks. With reinforcement ribs added to weak points, the plastic mix includes a fiber reinforcement that is added during construction to increase longevity and help eliminate another failure point.
