Aluminum Radiator 55-57 Chevy w/LS Engine

The Aluminum Radiator 55-57 Chevy w/LS Engine from Northern Radiator is designed specifically for hot rodders and resto-mod enthusiasts who are converting classic first-generation Chevrolets to modern LS powerplants. This radiator addresses the cooling needs that arise when upgrading to LS architecture, providing an effective solution for maintaining optimal engine temperatures.

Constructed with high-efficiency aluminum tubes and fins, this radiator maximizes heat dissipation while maintaining a compact footprint that fits within the original radiator cavity. The aluminum construction is approximately 40% lighter than traditional copper-brass designs, offering significant advantages in weight-sensitive applications. Additionally, the all-aluminum design resists corrosion, ensuring long-lasting performance.

This radiator is particularly beneficial for builders upgrading to LS1, LS2, LS3, or similar small-block LS variants in first-generation Chevys, where cooling demands are critical. With dimensions of 19 x 7.25 x 37.25 inches, it ensures a direct bolt-in fitment to 1955–1957 Chevrolet frames without the need for trimming or fabrication, preserving the vehicle's originality while optimizing engine bay space.
