High-Flow Radiator for 1973-76 Chevy Corvette LS Swap

Engineered for your 1973 to 1976 Corvette LS swap, the 26 inch core width and premium aluminum design maximize coolant capacity, improve airflow, and reduce radiator weight. Built in the USA with corrosion resistant construction and precision fit mounts for Y-Body frames, this radiator maintains optimal engine temperatures in city traffic and highway cruising while supporting long term vehicle value.

26 Inch Wide Core Radiator for 1973-1976 Chevy Corvette LS Swap Manual Trans

Installing an LS powerplant into a 1973 to 1976 Corvette manual transmission chassis demands a cooling solution that outperforms the OE setup and this 1973-1976 Corvette Radiator 26" Wide Core meets that need. With its expanded core width it moves more coolant through the system and maintains stable engine temperatures even during stop and go traffic or spirited driving. Crafted from durable aluminum and assembled in the USA it provides efficient heat dissipation that helps protect internal components on every run.

26 Inch Core Optimized for LS Swap Cooling Efficiency

The 26 inch wide core expands the coolant volume and multiplies the contact surface area for the LS swap installation. By guiding coolant through a thicker and broader array of cooling channels, it maintains engine temperatures even during stop and go traffic or sustained highway runs. This design reduces the chance of heat soak and supports steady output under load. Enthusiasts will appreciate the stable thermal performance that protects internal components during spirited driving sessions.

Premium Aluminum Assembly for Rapid Heat Dispersion

Constructed from premium aluminum, this radiator combines low weight with high thermal conductivity to accelerate heat rejection from the engine block. Aluminum resists corrosion and tolerates repeated heating and cooling cycles without cracking or deforming. The overall reduction in mass compared to heavier alternatives also eases stress on radiator mounts and hoses. This material choice ensures that cooling demand from the LS engine is met with rapid temperature control and durable service.

Bare Metal or Black Epoxy Layer for Corrosion Defense

Buyers can choose between a classic bare metal finish or a black epoxy layer that adds a protective barrier against road salt and debris. The bare aluminum surface offers direct heat transfer and an authentic mechanical look, while the epoxy coating seals the core walls to prevent oxidation in harsh environments. Both finishes are applied to withstand daily driving or weekend track use. Each option preserves the integrity of the radiator and keeps it looking sharp over time.

USA Craftsmanship Delivering Exact Fitment and Durability

Made in the United States, this radiator benefits from local fabrication standards that target precise fitment within the 1973 to 1976 Corvette manual transmission chassis. Critical dimensions and mounting points align without the need for modification, reducing installation time and ensuring a seamless upgrade. This homegrown approach also supports consistent build quality and long term reliability. Owners find that the exact match to original mounting provisions helps maintain resale value while delivering improved cooling performance.
