1955-1957 Chevy TriFive Radiator for LS and LT Engine Swaps in 150/210/Bel Air/Delray
When you install an LS or LT powerplant into a TriFive chassis, coolant stability becomes critical and the 1955-1957 Chevy Radiator (Auto Trans) delivers reliable temperature control without the need for custom supports. Featuring TIG welded aluminum core and tanks that shed weight and resist corrosion, this radiator aligns with factory mounting points for a direct fit on Chevy 150, 210, Bel Air and Delray frames. Its design channels coolant evenly through compact passages to keep engine temperatures stable during daily driving or more spirited highway runs. Installation remains simple thanks to precise attachment points that eliminate custom brackets and maintain the classic underhood appearance.
Precision TIG Welding Ensures Leak Free Integrity
The radiator uses 100% TIG welded aluminum for both core and tanks to create uniform seams that resist fatigue and leaks. This welding method fuses material surfaces without filler rod inconsistencies, delivering a strong bond that endures vibration and thermal cycles produced by LS and LT powerplants. Each weld undergoes rigorous inspection to ensure maximum integrity under demanding conditions. By avoiding multi stage joining techniques, the design reduces potential weak points and ensures consistent coolant flow. This robust fabrication underpins dependable cooling in every driving scenario.
High Conductivity Aluminum Core for Fast Heat Transfer
The high quality aluminum core excels at drawing heat away from the engine and into the cooling medium quickly. Its thin walls and compact coolant passages promote uniform temperature distribution, improving thermal efficiency and fast heat rejection. Aluminum's natural corrosion resistance and low density reduce overall weight while preserving core strength and durability. Together these properties keep coolant temperatures stable under different driving conditions and help extend engine life by preventing hot spots and thermal stress.
Selectable Bare Aluminum or Black Epoxy Finish
Owners can choose between a classic bare aluminum or a black epoxy coating to match underhood style preferences. The epoxy finish adds a protective layer that guards against surface corrosion and road debris while retaining core performance. Bare aluminum offers a clean look and can be custom polished or painted to blend with restoration themes. Both finishes maintain low mass and allow superior heat transfer without sacrificing durability or visual appeal.
Direct Installation on 1955 to 1957 Chevy TriFive Chassis
This design fits Chevy 150, Chevy 210, Bel Air and Delray models from 1955 to 1957 with automatic transmission without the need for custom supports. Mounting points align precisely with factory locations, so the underhood area retains its vintage appearance. Installers avoid frame modifications or bracket fabrication, cutting labor time and reducing the chance for fitment errors. The result is reliable cooling performance with minimal effort and preserved resale appeal.
