1973-1976 Chevy Corvette LS Swap Radiator 26 Inch Wide Core Manual Trans
When dropping an LS engine into a 1973 to 1976 Corvette manual transmission chassis, the original radiator often fails to keep coolant temperatures in check during city driving or spirited highway sessions. This 26 inch wide core radiator expands both coolant capacity and contact surface to improve thermal management even under heavy load. Built in the USA from high quality aluminum, it resists corrosion and holds up to repeated heating cycles. Installation is straightforward thanks to precision mounting points that align with the Y Body frame without modification.
Expanded Core Design Enhancing LS Cooling Performance
The 26-inch core width significantly increases coolant capacity and surface contact area, ensuring the LS engine maintains stable temperatures even in heavy traffic or spirited runs. By channeling coolant through a broader array of passages, the radiator minimizes heat soak and sustains consistent thermal control under load. This expanded design supports rapid dissipation of engine heat, protecting critical components and reducing the risk of overheating during extended highway cruising or stop-and-go driving. Enthusiasts will notice improved temperature stability that preserves performance during demanding sessions.
Aluminum Construction Balancing Weight and Heat Rejection
Crafted entirely from high quality aluminum, this radiator offers an ideal combination of low mass and exceptional thermal conductivity. Aluminum's inherent resistance to corrosion and fatigue allows it to withstand repeated heating cycles without cracking or warping. The lighter structure also eases stress on mounting brackets and hoses, contributing to a more reliable underhood assembly. Overall, the choice of aluminum accelerates heat transfer away from the engine block, delivering swift temperature control for the LS swap setup.
Finish Options Delivering Long-Lasting Corrosion Protection
Buyers can select a bare aluminum finish for maximum heat transfer and a sleek mechanical look, or opt for a black epoxy coat that seals surfaces against road salt and debris. The uncoated version provides direct path for thermal conduction, while the epoxy layer offers a barrier to moisture and oxidation in harsh conditions. Both finishes are applied with precision to maintain the radiator's integrity and ensure service durability. This flexibility lets owners tailor corrosion defense to their driving environment without compromising performance.
United States Craftsmanship for Precise Fitment
Manufactured in the USA to exacting standards, this radiator aligns precisely with the 1973-1976 Corvette manual transmission Y-Body frame, eliminating the need for modifications. Critical mounting points and inlet/outlet dimensions match the original provisions, streamlining the installation process and reducing labor time. Local fabrication ensures consistent quality control, resulting in a dependable upgrade that maintains chassis geometry and resale appeal. The result is a seamless integration that upholds both form and function.
