Hyper-Cool Trans Cooler Kit -8an

The DERALE Hyper-Cool Trans Cooler Kit -8an is engineered for serious automotive enthusiasts and mechanics who demand precise transmission temperature management in modified or high-performance vehicles. Transmission fluid degradation accelerates exponentially above 200°F, causing viscosity breakdown, seal failure, and catastrophic gearbox damage—especially under load or during sustained driving. This dedicated cooler kit addresses that critical gap by managing heat before it compromises your transmission's integrity and longevity.

The -8an line size designation indicates this kit uses 8 AN (AN8) hose fittings and connections, delivering significantly larger flow passages than OEM or -6an setups. DERALE's aluminum core radiator design maximizes surface area for efficient heat rejection while minimizing pressure drop—critical when routing transmission fluid through external circuits. The modular assembly allows flexible mounting in confined engine bays, with compact overall dimensions (12.5 × 6.85 × 17.85 inches) that accommodate domestic and import platforms. Stainless steel braided hoses resist abrasion and ozone degradation, and heavy-duty brackets ensure vibration isolation and durability through thousands of thermal cycles.

This cooler excels in vehicles running higher stall converters, custom transmissions, towing applications, or street/strip duty where stock thermal management falls short. Installation requires basic line routing from the transmission to the cooler and return, with the -8an fittings ensuring compatibility with modern high-flow transmission circuits. Whether you're protecting a freshly built transmission or preventing failure in a heavily modified engine bay, the DERALE Hyper-Cool Trans Cooler Kit -8an delivers the flow capacity and reliability that professionals and enthusiasts trust.
