26 Inch Wide Core LS Radiator for 1973-1976 Chevy Corvette Y-Body
For LS engine swaps into the 1973-1976 Corvette Y Body manual chassis, the 1973-1976 Corvette Radiator 26 inch Wide Core (Manual Trans) supplies a 26 inch wide core to boost coolant volume and air flow area, preventing temperature spikes during city use or highway cruising. Made in the USA from aluminum, this radiator mounts to original manual transmission points without altering frame geometry and aligns inlet and outlet tubes with factory hoses and brackets to reduce install time and leak risk. Available in bare aluminum or black epoxy finish, it offers corrosion protection in varied climates.
Core Specification and Cooling Capacity
The 1973 to 1976 Corvette radiator features a 26 inch wide core engineered to optimize coolant flow for LS engine installations paired with a manual transmission. This expanded width delivers an increased surface area for heat rejection, which directly enhances operating temperature stability under demanding driving conditions. By maintaining consistent coolant temperatures during highway cruising, spirited canyon runs or track sessions, the design minimizes the risk of thermal stress on critical engine components. The result is improved durability and sustained performance over extended use.
Aluminum Construction and Thermal Efficiency
Built entirely from high quality aluminum, this radiator combines light mass with superior conductivity to accelerate heat transfer away from the coolant. Aluminum's natural resistance to corrosion ensures the core remains free of rust and scale buildup, promoting long service life. Precision fin and tube layouts maximize airflow while minimizing pressure drop across the unit, preserving cooling system efficiency. Every joint is fusion welded to create a robust seal that withstands vibration and thermal cycling, delivering reliability session after session.
MuscleRods Mounting Integration
Designed to interface seamlessly with MuscleRods mounting platforms, this radiator aligns perfectly with existing support brackets and hood line clearances on 1973-1976 Corvette chassis. Proper engine placement and drivetrain angles are retained, ensuring that the radiator does not interfere with firewall clearance, belt drive assemblies or accessory pulleys. The bracket locations match factory points for straightforward installation, reducing the need for custom fab work and preserving chassis geometry and cooling line routing.
Craftsmanship in the USA
Assembled and tested in the United States, this Corvette radiator adheres to stringent quality control standards at every stage of production. Each unit undergoes pressure testing to confirm leak-free performance and is hand-inspected to verify weld integrity and core straightness. Domestic sourcing of aluminum stock and local manufacturing ensure consistent material properties and rapid fulfillment. Backed by dedicated customer support, this radiator offers peace of mind for enthusiasts who demand durable, American-made components.
