TriFive LS LT Radiator Core for 1955-1957 Chevy 150/210/Bel Air/Delray

High-grade aluminum construction and precision machining deliver superior thermal efficiency and rapid heat rejection for LS and LT powerplants in your 1955 through 1957 TriFive 150, 210, Bel Air and Delray models. Manufactured in the USA with 100 percent TIG welded tanks and core, this radiator guarantees corrosion resistance, lightweight durability and a factory accurate fit that enhances long term performance and resale value.

LS and LT Swap Radiator for 1955-1957 Tri-Five Chevy 150/210/Bel Air/Delray Auto Trans

Swapping an LS or LT engine into a 1955 through 1957 Chevy 150, 210, Bel Air or Delray chassis makes reliable temperature control essential and the 1955-1957 Chevy Radiator (Auto Trans) is engineered to keep coolant temperatures steady without the need for custom supports. With its precision TIG welded aluminum construction, the core and tanks form a uniform assembly that resists leaks and corrosion while shedding unnecessary weight. By matching factory attachment points, installation remains straightforward and underhood authenticity is preserved for a clean, stock appearance.

Precision TIG Welding for Ultimate Leak Resistance

The 1955-1957 Chevy Radiator relies on a specialized TIG welding process that fuses the aluminum core and tanks with exceptional uniformity. By eliminating filler inconsistencies common in other joining methods, each seam forms a seamless bond that stands up to the constant vibration and heat cycles generated by LS and LT powerplants. Welds are meticulously inspected to ensure they meet stringent strength requirements, reducing the risk of coolant leaks over time. This construction not only preserves the integrity of coolant flow but also contributes to an overall lighter assembly. Technicians and fabricators benefit from a radiator that resists fatigue without bulky reinforcement plates or extra sealants. The result is a dependable cooling unit that remains robust mile after mile.

Optimized Aluminum Core for Rapid Heat Transfer

Crafted from premium aluminum, the radiator's core features thin-walled coolant passages designed to maximize surface contact with the liquid. This geometry accelerates heat rejection by channeling fluid evenly through every passage, preventing localized hot spots that could stress engine components. Aluminum's natural resistance to corrosion ensures the core maintains its thermal performance over years of use, even with varying coolant chemistries. A lower overall mass also helps reduce front-end weight, enhancing handling dynamics without compromising strength. Drivers will notice stable temperature readings during both casual cruising and spirited highway runs. Over time, consistent heat control can extend engine life by keeping cylinder heads and blocks within their ideal temperature band.

Custom Finish Choices for Corrosion Protection and Style

Owners can select a bare aluminum finish for a classic underhood look or choose the black epoxy option for additional surface protection. The epoxy coating provides a guard against road debris and moisture that can pit or discolor exposed metal over the years. Meanwhile, the uncoated aluminum variant invites custom polishing or paint treatments to match restoration themes or show-car standards. Both finishes are applied without adding significant mass, so thermal transfer remains virtually unchanged. Beyond aesthetics, these surface options help maintain a showroom appearance while shielding the core from environmental contaminants. The clean lines and factory-style appearance ensure the radiator complements any TriFive project.

Direct Bolt in Fit for TriFive LS and LT Installation

Designed specifically for 1955 through 1957 Chevy 150, 210, Bel Air and Delray models with automatic transmission, this radiator aligns precisely with original frame mounts and shroud brackets. Installers can avoid time-consuming bracket fabrication or frame modifications, speeding up the swap process and reducing the chance of fitment errors. By matching factory attachment points, the unit preserves the authentic underhood profile that collectors and restorers demand. This precise fit also simplifies hose routing and fan shroud alignment, so there is no need for custom supports or spacer plates. Quick bolt-in installation means the engine bay stays tidy and professional. In practical terms, reliable fitment translates to fewer post-install adjustments and a smoother path to road readiness.
