1955-1957 TriFive Chevy Radiator for LS and LT Engine Swaps
When installing an LS or LT mill into a 1955 to 1957 Chevy 150, 210, Bel Air or Delray chassis, maintaining steady coolant temperatures is essential and this radiator is engineered to deliver just that. Equipped with a 100% TIG welded aluminum core and tanks, it resists corrosion and sheds weight for improved front end balance while matching factory mounting points for a direct fit. By combining high conductivity aluminum with precision fitment, it keeps coolant temps stable on both daily drives and spirited runs.
Expert TIG Welding for Leak Free Reliability
The radiator employs 100% TIG welded aluminum core and tanks to create seamless joints that resist leaks and fatigue. This precision method fuses aluminum surfaces with high consistency, ensuring each weld withstands vibration and thermal stress from LS and LT engines. By eliminating filler rod inconsistencies, the radiator maintains steady coolant flow under heavy loads. As a result, owners can trust its performance on both daily trips and spirited drives.
High Conductivity Aluminum Core for Rapid Heat Rejection
Constructed from high quality aluminum, the core maximizes thermal conductivity to draw heat away from the engine quickly. Aluminum's low density reduces underhood mass while still providing structural strength and natural corrosion resistance. The design channels coolant through compact passages, promoting uniform temperature distribution. Together these features keep operating temperatures stable, enhancing engine efficiency and longevity.
Direct Fitment Simplifies Installation on TriFive Chassis
Engineered for 1955 to 1957 Chevy 150, 210, Bel Air and Delray platforms, the radiator aligns exactly with factory mounting points for models with automatic transmissions. This direct fitment removes the need for custom brackets or frame alterations, cutting install time and labor costs. The result is a clean underhood appearance that honors the classic style while accommodating modern LS and LT engine packages. Enthusiasts appreciate how it preserves the vintage look without compromising on cooling capability.
