LS LT Swap Radiator with Fans for 1967-87 SquareBody Trucks

Superior thermal management arrives with this 18.5 inch tall aluminum radiator and dual fans custom sized for LS and LT swaps, maintaining stable engine temperatures in city traffic and on the track. Engineered for a drop in fit on 1967 to 1987 C/KSeries trucks without fabrication, its corrosion resistant aluminum construction delivers fast heat rejection and lasting reliability while built in the USA for consistent quality.

1967-1987 GM SquareBody C/K Truck Radiator for LS/LT Engine Swaps

If your project involves swapping an LS or LT motor into a 1967-1987 SquareBody C/K truck, the 1967-1987 GM Truck Radiator 18.5" Tall (Auto Transmission) with Fans is designed to maintain consistent engine temperatures in street and off-road driving. Engineered from US-made aluminum for efficient heat rejection, this radiator drops into C10, C15, K10, K15, Blazer and Suburban frames with minimal modifications. With dual high performance cooling fans preinstalled and a precision fit for automatic transmission setups, it delivers reliable temperature control without extra fabrication.

Seamless Cooling Upgrade for C/K Series Trucks

This 18.5 inch tall radiator is engineered to match the factory mounting points of 1967 through 1987 C10, C15, K10, K15, Blazer and Suburban frames with automatic transmission setups. By aligning with the original core height and inlet locations, it installs without cutting or custom brackets, saving valuable time during LS or LT engine conversions. The precision fit maintains proper hood clearance and preserves front end geometry, allowing builders to focus on performance tuning rather than fabrication hurdles. Preinstalled dual fans further streamline the upgrade by delivering ready-to-run cooling straight from the crate.

High Quality Aluminum Design for Fast Heat Rejection

Constructed from US made aluminum, the radiator core and tanks leverage the metal's excellent thermal conductivity to move heat from engine coolant to incoming air quickly. Its lightweight structure reduces front end mass while still providing the mechanical strength needed to resist vibration and road impacts. Aluminum also offers superior resistance to corrosion compared to traditional copper-brass designs, ensuring stable performance over many seasons. For street or off road use, this material choice delivers consistent temperature control under demanding conditions.

Dual Fan Setup for Consistent Airflow Management

Featuring two high flow electric cooling fans mounted directly to the radiator face, this system ensures continuous air movement even when the truck is stationary or crawling at low speed. The twin-fan array increases total air volume compared to a single-fan design, reducing risk of heat soak in traffic or on steep grades. Each fan is calibrated to balance airflow and electrical draw, preventing alternator overload while maintaining peak cooling capacity. The result is a more stable under hood environment, which supports optimal engine performance and longevity.

Classic Aluminum Finish or Black Epoxy for Style and Protection

Owners can choose the raw aluminum variant to highlight polished welds and buffer marks or select a durable black epoxy coating for added surface protection. Both finishes are applied in the USA using processes that bond tightly to the substrate, guarding against chips and moisture infiltration. The epoxy option helps conceal any under hood stains while offering a subtle contrast against engine components. Finish choice allows each build to reflect personal taste without compromising thermal efficiency or structural integrity.
