If you are tackling an LS or LT engine swap in a 1967 through 1987 C/K Series Chevy or GMC truck including C10, C15, K10, K15, Blazer and Suburban this radiator delivers consistent temperature control and exact factory bracket alignment. The 1967-1987 GM Truck Radiator 18.5 inch Tall (Manual Trans) with Fans offers a direct bolt in cooling solution built from high quality aluminum for drop in install that requires no trimming or adapters. Dual high performance fans sustain airflow at idle and under load with pre wired connectors that plug into factory style circuits. Finish options include bare aluminum or black epoxy coating applied in the USA for lasting corrosion resistance and easy cleaning.
Optimized Cooling Capacity for 1967–1987 GM Trucks
The 1967–1987 GM Truck Radiator 18.5 inch Tall is engineered specifically for manual transmission models. Its core height increases coolant volume by 20 percent over stock units, improving heat rejection under sustained load. Compatibility with LS and LT powerplants ensures stable operating temperatures during towing, haul duty or spirited driving on classic GM frames.
Integrated Dual High Performance Fans
Two high performance fans arrive preinstalled, eliminating guesswork on airflow requirements. Each fan is calibrated to activate at precise coolant thresholds, delivering consistent air movement at low speeds and during idle periods. This setup reduces hotspots across the core and offers plug and play connection to factory harnesses, ensuring effortless installation and reliable operation.
All-Aluminum Build and Domestic Craftsmanship
Constructed from robust aluminum, the radiator core and tanks resist corrosion while maximizing thermal transfer. Precision TIG welding at each seam secures leak-proof joints under high pressure. Every unit is assembled and tested in the USA, adhering to strict dimensional checks and pressure evaluations to guarantee long life, light weight and repeatable performance in demanding environments.
Direct Fit with MuscleRods Mounts
Designed to integrate seamlessly with MuscleRods mounts, this radiator maintains factory-correct engine position and drivetrain angle. The mounting feet align with existing chassis pads, requiring no frame modifications. This synergy preserves drive-shaft geometry, simplifies installation in '67-'87 GM pickups, and supports both LS and LT conversions with consistent cooling efficiency.
