1973-1976 Chevy Corvette LS Swap Radiator 26 Inch Wide Core Manual Trans
If you are installing an LS engine in a 1973 to 1976 Chevy Corvette manual transmission chassis this 26 inch wide core radiator addresses the common issue of heat soak during heavy traffic or spirited cruising. By offering a broader coolant path and greater capacity the radiator maintains stable temperatures even under load. It is crafted from aluminum in the USA to resist corrosion and manage repeated heating cycles without fatigue. Precision mounting points align with the Y Body frame so installation fits without altering original provisions.
Extra Wide Core Enhancing LS Cooling Efficiency
The 26 inch core width of this radiator dramatically expands coolant volume and surface contact area for more effective heat exchange. In stop and go traffic or during spirited highway runs the broader passages reduce heat soak by allowing coolant to absorb and dissipate thermal energy at a higher rate. This design achieves more consistent temperature control under varying load conditions and protects vital engine components from thermal fatigue. As a result, drivers benefit from stable gauge readings during extended idling, steep climbs, or sustained high speed cruising.
Aluminum Structure Optimizing Weight and Heat Transfer
Crafted entirely from high quality aluminum, the radiator balances low mass with excellent thermal conductivity. Aluminum's inherent resistance to corrosion and fatigue ensures that repeated heating cycles will not lead to cracking or warping over time. The lighter construction also reduces stress on hoses and mounting brackets, contributing to a more reliable underhood assembly. Enhanced heat transfer away from the LS engine helps maintain ideal operating temperatures, supporting peak performance and extending component service life.
Corrosion Shield with Bare Aluminum or Epoxy Finish
Buyers can choose between a bare aluminum surface for maximum thermal conduction or a black epoxy coat that seals the metal against moisture and road contaminants. The uncoated option offers direct heat flow through the core, while the epoxy layer serves as a durable barrier to oxidation in harsh environments. Both finishes are applied in controlled conditions to ensure uniform thickness and adhesion. This flexibility allows owners to match the level of corrosion protection to their climate and driving habits without sacrificing cooling efficiency.
Precision Fitment to 1973–76 Corvette Manual Frame
Manufactured in the USA to precise tolerances, this radiator aligns perfectly with the Y Body frame of 1973 through 1976 Corvettes equipped with a manual transmission. Critical mounting points, inlet and outlet dimensions, and core height mirror the original design, eliminating the need for cutting or welding. This exact fit speeds installation and preserves factory chassis geometry. Local fabrication ensures consistent quality control so each unit delivers reliable performance and helps maintain resale value.
