Radiator w/Fans C-10 Trk LS 73-86 Trans Raw

The Radiator w/Fans C-10 Trk LS 73-86 Trans Raw is a specialized cooling solution engineered specifically for enthusiasts performing LSX conversions in 1973-1986 GM fullsize trucks. When swapping modern powerplants into classic Square Body chassis, managing thermal loads is a primary concern for long-term reliability. This DeWitts Radiator kit provides a purpose-built solution that replaces restrictive factory cooling components with a high-capacity aluminum unit designed to handle the increased heat output of high-performance LS engines.

This kit features a 32-inch wide by 21.5-inch high aluminum core, offering significantly more surface area for heat exchange than standard copper-brass replacements. The aluminum construction is critical for efficient heat transfer, while the natural raw finish provides a professional, clean aesthetic under the hood. For those looking to buy a complete system, this unit includes integrated electric fans, ensuring consistent airflow even at low speeds or during heavy idling—operating conditions where traditional mechanical fans often underperform in modified truck applications.

Engineering specifications for the Radiator w/Fans C-10 Trk LS 73-86 Trans Raw include a passenger-side inlet and outlet configuration, which aligns perfectly with modern LS-series water pump locations to simplify hose routing. The inclusion of an internal transmission cooler makes this an ideal choice for builds utilizing automatic transmissions, such as the 4L60E or 4L80E commonly paired with these swaps. By consolidating the cooling system into a single high-efficiency package, builders can maximize space within the engine bay while ensuring optimal thermal regulation.

Reviewing the dimensions of 32" W x 21.5" H x 6.75" D, it is clear this unit is built to utilize the full volume of the GM truck core support. Whether the goal is a reliable daily driver or a high-horsepower street machine, this DeWitts Radiator system provides the thermal stability required for modern engine performance. Investing in a purpose-built LS conversion radiator eliminates the guesswork of universal fitments and ensures the vehicle remains operational under demanding conditions. Specifications for this kit are designed for a direct-fit experience in the 1973-1986 GM truck platform.
