16 Row Core 5in. Tall -6an Inlets Trans/Oil Co

The DERALE 16 Row Core 5-inch Tall transmission and oil cooler with -6AN inlets (part number 51606) is a compact plate-type fluid cooler engineered for high-performance vehicles and custom builds requiring efficient thermal management. Featuring a 13 x 6.438 x 2-inch aluminum construction with black powder coat finish, this universal cooler integrates seamlessly into tight engine bays where space constraints demand a low-profile solution.

The 16-row core design maximizes heat dissipation surface area in a minimal footprint, critical for vehicles that see sustained high-load operation. The plate-type configuration offers superior flow characteristics compared to traditional tube-and-fin designs, reducing pressure drop while maintaining effective cooling capacity. Dual 10 AN female O-ring inlets and outlets provide secure, leak-proof connections, while the included 6 AN male adapters enable flexible plumbing configurations to match existing fuel or transmission line sizing. The aluminum core resists corrosion and weighs just 3.04 pounds, minimizing overall vehicle weight while delivering the thermal performance demand-heavy applications require.

This cooler addresses the needs of street rod builders, marine engine installations, high-output transmission rebuilds, and custom off-road platforms where OEM cooling infrastructure falls short. The universal mounting design and compact 5-inch height make it ideal for custom fabrication projects where engine bay real estate is limited. Professional builders and enthusiasts pursuing reliable long-term performance in modified vehicles depend on DERALE's thermal management expertise to prevent fluid degradation and extend component lifespan.

When selecting a transmission or oil cooler, the balance between core density, flow efficiency, and installation space determines whether cooling is adequate under peak demand. The 16-row configuration represents a proven middle ground—offering thermal capacity sufficient for most custom applications while maintaining the low-profile package height essential for tight engine compartments.
