Frame Rail Cooler 17in ( -6AN)

The DERALE Frame Rail Cooler 17in (-6AN) is a compact yet effective fluid cooling solution designed for custom and high-performance automotive builds where underhood space is limited. This cooler is essential for cooling transmission fluid, power steering fluid, or engine oil in tight installations where traditional large-core radiators won't fit.

Built to DERALE's proven standards, this 17-inch frame rail cooler features a core profile of 3 x 3 inches that maximizes cooling surface area without consuming precious engine bay real estate. The -6AN inlet and outlet ports are industry-standard for custom plumbing systems, allowing easy integration with braided stainless hose lines and quick-disconnect fittings common in modern street performance builds.

Weighing just 1.12 lbs, the aluminum construction provides excellent thermal conductivity while remaining lightweight—a critical consideration when fine-tuning vehicle weight distribution or optimizing suspension geometry. This cooler is ideal for builders tackling LS swaps, modern engine conversions, or retrofit projects where stock cooling systems don't match new hardware. Frame rail mounting keeps the cooler low and hidden from view while ensuring efficient airflow.
