LS and LT Swap Radiator for 1967-1987 C/K Series Trucks and SUVs
Swapping an LS or LT engine into your 1967-1987 C/K Series truck demands a cooling system that can handle modern output and our 20.75 inch tall radiator with dual electric fans is built to fill that role. With a core designed for manual transmission setups this radiator bolts in without extra modifications and ensures steady temperatures whether you are towing or cruising in traffic. Every unit is built from thickwall aluminum and includes a pair of efficient fans to prevent heat soak under load. Designed for wide fitment across C10, K10, Blazer and Suburban models this radiator offers reliable performance for your swap project.
High Quality Aluminum Core for Superior Heat Rejection
The 20.75 inch tall core is crafted from thickwall aluminum that excels at conducting and shedding heat rapidly under heavy loads. Aluminum's natural resistance to corrosion ensures the radiator maintains peak thermal performance over years of towing or spirited driving. Its lightweight construction also reduces front end weight, preserving handling characteristics on both road and track. Built in the USA, this core offers consistent wall thickness and reliable weld integrity for long term durability.
Dual Electric Fans Deliver Consistent Airflow Under Stress
Two high performance electric fans are pre installed to provide a continuous flow of air even when vehicle speed drops. This setup prevents heat soak during extended idles or traffic jams, keeping engine temperatures within the ideal range. By activating on demand, the fans reduce strain on the cooling system and improve fuel economy compared with belt driven units. Their efficient blade design and shroud integration also minimize noise while maximizing airflow across the entire core.
Precision Fit for Manual Transmissions in C/K Series Trucks
Designed specifically for 1967 to 1987 C10, K10, Blazer and Suburban models with manual transmissions, this radiator bolts in without frame modifications or custom spacing. The direct fit approach preserves original mounting points, lowering installation time and avoiding the need for shims or spacers. Its height and inlet outlet locations line up precisely with LS and LT engine swaps, ensuring proper hose routing and fan clearance. The result is a seamless blend of classic truck style and modern powertrain efficiency.
Custom Finish Options for Lasting Durability and Style
Choose between a polished bare aluminum look for a timeless engine bay presence or a black epoxy coating for a tough matte appearance. Both finishes enhance corrosion resistance by sealing the surface and guarding against road debris and moisture. The epoxy version also offers a uniform black finish that hides stains and makes maintenance easier. These coating choices ensure your radiator remains as striking in appearance as it is reliable in function.
